+
+This is an extra tool, not bundled with the default waf binary.
+To add the boost tool to the waf file:
+$ ./waf-light --tools=compat15,boost
+	or, if you have waf >= 1.6.2
+$ ./waf update --files=boost
+
+When using this tool, the wscript will look like:
+
+	def options(opt):
+		opt.load('compiler_cxx boost')
+
+	def configure(conf):
+		conf.load('compiler_cxx boost')
+		conf.check_boost(lib='system filesystem')
+
+	def build(bld):
+		bld(source='main.cpp', target='app', use='BOOST')
+
+Options are generated, in order to specify the location of boost includes/libraries.
+The `check_boost` configuration function allows to specify the used boost libraries.
+It can also provide default arguments to the --boost-static and --boost-mt command-line arguments.
+Everything will be packaged together in a BOOST component that you can use.
+
+When using MSVC, a lot of compilation flags need to match your BOOST build configuration:
+ - you may have to add /EHsc to your CXXFLAGS or define boost::throw_exception if BOOST_NO_EXCEPTIONS is defined.
+   Errors: C4530
+ - boost libraries will try to be smart and use the (pretty but often not useful) auto-linking feature of MSVC
+   So before calling `conf.check_boost` you might want to disabling by adding:
+   	conf.env.DEFINES_BOOST += ['BOOST_ALL_NO_LIB']
+   Errors:
+ - boost might also be compiled with /MT, which links the runtime statically.
+   If you have problems with redefined symbols,
+		self.env['DEFINES_%s' % var] += ['BOOST_ALL_NO_LIB']
+		self.env['CXXFLAGS_%s' % var] += ['/MD', '/EHsc']
+Passing `--boost-linkage_autodetect` might help ensuring having a correct linkage in some basic cases.

+GNU GENERAL PUBLIC LICENSE
+==========================
+Version 3, 29 June 2007
+=======================
+
+> Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+  Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
+
+# Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+# TERMS AND CONDITIONS
+
+## 0. Definitions.
+
+  _"This License"_ refers to version 3 of the GNU General Public License.
+
+  _"Copyright"_ also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  _"The Program"_ refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as _"you"_.  _"Licensees"_ and
+"recipients" may be individuals or organizations.
+
+  To _"modify"_ a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a _"modified version"_ of the
+earlier work or a work _"based on"_ the earlier work.
+
+  A _"covered work"_ means either the unmodified Program or a work based
+on the Program.
+
+  To _"propagate"_ a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To _"convey"_ a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+## 1. Source Code.
+
+  The _"source code"_ for a work means the preferred form of the work
+for making modifications to it. _"Object code"_ means any non-source
+form of a work.
+
+  A _"Standard Interface"_ means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The _"System Libraries"_ of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The _"Corresponding Source"_ for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+## 2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+## 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+## 4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+## 5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+## 6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A _"User Product"_ is either (1) a _"consumer product"_, which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  _"Installation Information"_ for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+## 7. Additional Terms.
+
+  _"Additional permissions"_ are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+## 8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+## 9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+## 10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An _"entity transaction"_ is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+## 11. Patents.
+
+  A _"contributor"_ is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's _"essential patent claims"_ are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+## 12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+## 13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+## 14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+## 15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+## 16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+## 17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+# END OF TERMS AND CONDITIONS
+--------------------------------------------------------------------------
+
+
+# How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type 'show c' for details.
+
+  The hypothetical commands _'show w'_ and _'show c'_ should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+NLSR - Named Data Link State Routing Protocol
+=============================================
+
+## Overview
+
+NLSR is a routing protocol in NDN that populates NDN's Routing Information Base. NLSR
+will continue to evolve alongside the Named Data Networking [protocol](http://named-data.net/doc/ndn-tlv/).
+
+NLSR is an open and free software package licensed under the GPL 3.0 license and free to all
+Internet users and developers.  For more information about the licensing details and
+limitations, refer to [COPYING.md](https://github.com/named-data/NLSR/blob/master/COPYING.md).
+
+NLSR is developed by the members of the [NSF-sponsored NDN project team](http://named-data.net/project/participants/).
+For more details, please refer to [AUTHORS.md](https://github.com/named-data/NLSR/blob/master/AUTHORS.md).
+Bug reports and feedback are highly appreciated and can be made through the
+[Redmine site](http://redmine.named-data.net/projects/nlsr).
+
+The main design goal of NLSR is to provide a routing protocol to populate NDN's FIB.
+NLSR calculates the routing table using link-state or hyperbolic routing and produces
+multiple faces for each reachable name prefix in a single authoritative domain. NLSR
+will continue to evolve over time to include neighbor discovery and to become a full
+fledged inter-domain routing protocol for NDN.
+

-\section{Configuration File}
-\label{sec:configuration}
-
-NLSR's configuration file contains numerous parameters to control the behavior and performance of NLSR.
-The configuration file also includes the trust schema used by NLSR to verify LSA Data, Hello Data, and prefix update command Interests.
-
-\subsection{Naming Conventions}
-The NLSR naming convention is mostly arbitrary. For example, a router's name, maybe \texttt{\%C1.Router/router1}, is composed of two parts. \texttt{\%C1.Router} is the router ``tag'', and \texttt{router1} is the name or label of the router. Different entities are given different tags, depending on the context.
-
-\subsection{General Section}
-
-The \texttt{general} section in the configuration file includes parameters which deal with the general setup of the router, the behavior of the LSDB, and logging configuration.
-
-There are three parameters used to configure the router prefix of the router.
-The router prefix is the name that other routers in the network know this router by.
-\begin{itemize}
-\item \texttt{network} - the name of the network to which the router belongs; e.g., \texttt{/ndn}.
-\item \texttt{site} - the name of the site to which the router belongs; e.g., \texttt{/edu/memphis}.
-\item \texttt{router} - the name to identify the router; e.g., \texttt{/\%C1.Router/cs/pollux}.t
-\end{itemize}
-The router prefix is constructed by combining the three parameters following the format: \texttt{/<network>/<site>/<router>}.
-
-There are three parameters which affect the behavior of the LSDB.
-\begin{itemize}
-\item \texttt{lsa-refresh-time} - the time in seconds the router will wait before refreshing its LSAs (Default value: 1800; Valid values: 240 - 7200).
-\item \texttt{router-dead-interval} - the time in seconds after which an inactive router's LSAs are removed.
-The configured value for this parameter must be greater than \texttt{lsa-refresh-time}. (Default value: two times the value configured in \texttt{lsa-refresh-time}).
-\item \texttt{lsa-interest-lifetime} - the interest lifetime used for LSA Interests (Default value: 4; Valid values: 1 - 60).
-\end{itemize}
-
-The \texttt{log-level} parameter configures the verbosity of NLSR's logging.
-The possible \texttt{log-level} values are listed in increasing verbosity. That is, the value all the way to the left includes the values all the way to the right.
-\begin{verbatim}
-NONE < ERROR < WARN < INFO (Default) < DEBUG < TRACE < ALL
-\end{verbatim}
-
-Note that a log level also enables all log levels to its left. That is, setting log level to \texttt{TRACE} causes \texttt{ERROR, WARN, INFO} and \texttt{DEBUG} messages. to also be logged.
-
-The \texttt{general} configuration section also includes parameters to choose where the NLSR log file and the NLSR sequence number file are stored.
-The \texttt{log-dir} parameter is an absolute path to the directory where the NLSR log file should be written, and \texttt{seq-dir} is an absolute path to the directory where the NLSR sequence number should be written. The log directory must exist and be writable, or else NLSR will fail to start.
-
-\subsection{Neighbors Section}
-
-The \texttt{neighbors} section in the configuration file contains parameters that define the behavior of the Hello Protocol and the neighboring routers of the router.
-\begin{itemize}
-\item \texttt{hello-retries} - the number of times to retry a Hello Interest before deciding the neighbor is down (Default value: 3; Valid values: 1 - 10).
-\item \texttt{hello-timeout} - the interest lifetime for Hello Interests in seconds (Default value: 1, Valid values: 1 - 15).
-\item \texttt{hello-interval} - the time in seconds between sending each Hello Interest to a neighbor. (Default value: 60; Valid values: 30 - 90).
-\item \texttt{adj-lsa-build-interval} - when the Hello Protocol triggers an Adjacency LSA build, the LSDB will wait this amount of time in seconds before performing the Adjacency LSA build. This parameter is intended to allow for Adjacency LSA build requests to be aggregated and the build can then be performed once. (Default value: 5; Valid values: 0 - 5)
-\item \texttt{first-hello-interval} -  the time to wait in seconds before sending the first Hello Interests (Default value: 10; Valid values: 0 - 10).
-\item \texttt{face-dataset-fetch-tries} - how many times to re-fetch
-  the Face status dataset from NFD. (Default value: 3; Valid values: 1 - 10)
-\item \texttt{face-dataset-fetch-interval} - how often to fetch the
-  Face status dataset from NFD. This dataset is needed to communicate
-  with neighbors, but Face events are considered the main source of
-  this information. This dataset is intended as a backup to that
-  mechanism, so the interval is very long. (Default value: 3600. 
-  Valid values: 1800 - 5400)
-\end{itemize}
-
-The \texttt{neighbors} section also includes multiple \texttt{neighbor} subsections, each of which configures a neighbor of the router.
-The \texttt{neighbor} subsection includes:
-\begin{itemize}
-\item \texttt{name} - the router prefix of the neighboring router
-\item \texttt{face-uri} - the face that should be used to connect to the neighboring router
-\item \texttt{link-cost} - the cost metric for the link connecting this router to the neighbor router.
-\end{itemize}
-
-\emph{NB: NLSR no longer creates and configures Faces in NFD!} NLSR
-periodically fetches from NFD a dataset containing information about
-all of NFD's Faces. NLSR scans this information and internally
-configures neighbors with that information. Additionally, NLSR listens
-to activity from NFD concerning Faces. These two sources of
-information should cover all Faces; any neighbor not represented in
-these two sources of information will be assumed inactive or
-inaccessible, and will not be contacted.
-
-\subsection{Hyperbolic Section}
-
-Hyperbolic Routing is a greedy geometric routing technique available in NLSR. The best resource to understand how it works is its white paper. \cite{HyperbolicASF}
-
-The \texttt{hyperbolic} section in the configuration file is used to enable/disable hyperbolic routing and to specify the hyperbolic coordinates of the router.
-
-The \texttt{state} parameter indicates whether or not hyperbolic routing should be enabled. There are three possible values for this parameter: \texttt{on}, \texttt{off}, and \texttt{dry-run}. \texttt{on} enables hyperbolic routing; \texttt{off} disables hyperbolic routing (link-state routing is used); \texttt{dry-run} uses link-state routing to populate NFD's FIB, but will also perform the hyperbolic routing calculations and write them to the log file for debugging purposes.
-
-The \texttt{radius} parameter defines the router's radius in the hyperbolic coordinate system and \texttt{angle} defines the router's angle(s) in the hyperbolic coordinate system. There can be (d-1) angular coordinates in d-dimensional hyperbolic routing. Currently the testbed uses 2-dimensional hyperbolic routing with one radial and one angular coordinate.
-
-\subsection{FIB Section}
-
-The \texttt{fib} section in the configuration file contains two parameters: one to limit the number of next hops registered for each name prefix, and the amount of time to wait before calculating the routing table after a request is made.
-
-\texttt{max-faces-per-prefix} defines the maximum number of next hops that can be registered for a name prefix.
-This value is intended to reduce the FIB size for routers with a large number of neighbors.
-The default value for \texttt{max-faces-per-prefix} is \texttt{0} which indicates that all available next hops may be added to each name prefix. \texttt{max-faces-per-prefix} allows values between 0 and 60.
-
-\texttt{routing-calc-interval} is the time to wait in seconds after a routing table calculation is requested before actually performing the routing table calculation.
-This parameter is intended to limit the number of routing table calculations, which may be performance intensive on some systems.
-The default value for \texttt{routing-calc-interval} is 15 seconds and can be configured to be in the range of 0 to 15 seconds.
-
-\subsection{Advertising Section}
-
-The \texttt{advertising} section includes a list of name prefixes that the router should advertise as reachable through itself.
-Each name prefix that should be advertised should be in the following format: \texttt{prefix /name/to/advertise}.
-This section allows for static configuration of the advertised prefixes, but prefixes can be dynamically advertised and withdrawn using the Prefix Update Processor.
-
-\subsection{Security Section}
-
-The \texttt{security} section of the configuration file includes the configuration for NLSR's validators and the locations of certificates that should be published by the router.
-
-The \texttt{validator} subsection includes the configuration for the validator used by NLSR to verify the signatures of Hello Data and LSA Data.
-
-The \texttt{prefix-update-validator} configures the validator used by the Prefix Update Processor to verify that prefix update command Interests are signed by the operator of the router.
-
-The \texttt{security} section also allows configuration of which certificates should be published by the router using the \texttt{cert-to-publish} keyword.
-If the router should publish a certificate, the absolute path for the certificate file can be configured as \texttt{cert-to-publish} value.

+Release Notes
+=============
+
+NLSR version 0.1.0 (initial release)
+++++++++++++++++++++++++++++++++++++
+
+Release date: August 25, 2014
+
+The main design goal of NLSR is to provide a routing protocol to populate `NFD's
+<http://named-data.net/doc/NFD/current/>`_ RIB.  NLSR calculates the routing table using
+link-state or hyperbolic routing and produces multiple faces for each reachable name
+prefix in a single authoritative domain.
+
+**Included features**:
+
+- Produce a list of ranked forwarding options for each name prefix to facilitate NDN's adaptive forwarding strategies
+
+- Name Prefix advertisement
+
+  + Advertise availability of content through the configured router
+
+- Use `ChronoSync <https://github.com/named-data/ChronoSync>`_ to synchronize routers' LSA sequence numbers and Interest/Data to retrieve LSAs
+
+- Limit faces per prefix
+
+  + Configure maximum number of faces per prefix in NFD's RIB
+
+- Automatic NFD tunnel configuration and maintenance to neighbors
+
+- Routing protocol
+
+  + Link State routing
+  + Hyperbolic routing
+
+    + Calculates route cost based on a node's polar coordinates
+
+- Use a hierarchical trust model for routing within a single administrative domain
+
+- NFD Routing Information Base (RIB) consistency
+
+  + Provides shortest path next hops for efficient forwarding
+  + Keeps NFD's RIB updated on node failure and recovery

+Router Configuration
+====================
+
+.. toctree::
+..
+
+Example network and sample configuration
+----------------------------------------
+
+Assume that three routers in the same network, but at three different sites
+(``memphis.edu``, ``arizona.edu``, and ``colostate.edu``), are connected to each other to
+construct the following topology:
+
+::
+
+                        +-------------------------------------+
+                        | /ndn/edu/memphis/%C1.Router/router1 |
+                        +-------------------------------------+
+                            / 11                      12\
+                           /                             \
+          route-cost = 25 /                               \ route-cost = 30
+                         /                                 \
+                     17 /                                   \ 13
+    +-----------------------------------+ 7              10 +-------------------------------------+
+    |/ndn/edu/arizona/%C1.Router/router3|-------------------|/ndn/edu/colostate/%C1.Router/router2|
+    +-----------------------------------+   route-cost = 28 +-------------------------------------+
+
+                          Figure: Network Topology
+
+The number represents the connecting face id. For example,
+``/ndn/edu/memphis/%C1.Router/router1`` is connected to
+``/ndn/edu/arizona/%C1.Router/router3`` via face 11 and the route cost is 25. To reach
+``/ndn/edu/colostate/%C1.Router/router2`` via face 12, the route cost is 30.
+
+We will walk through setting up the faces and creating the configuration file for
+``/ndn/edu/memphis/%C1.Router/router1``.
+
+Step 1. Ensuring nfd is running
+-------------------------------
+
+Type the following in the terminal:
+
+::
+
+    nfd-status -f
+
+If you see ``ERROR: error while connecting to the forwarder (No such file or directory)``,
+``nfd`` is not running. Follow the instructions in `Getting started with NFD
+<http://named-data.net/doc/NFD/current/INSTALL.html>`_ to run nfd.
+
+Step 2. Determining FaceUri
+---------------------------
+
+Assume that ``/ndn/edu/arizona/%C1.Router/router3`` has hostname ``router3.arizona.edu``,
+``/ndn/edu/colostate/%C1.Router/router2`` has IP address ``79.123.10.145``, and that all
+routers in the network have agreed to sync data with name prefix ``/ndn/nlsr/sync``.
+``/ndn/edu/memphis/%C1.Router/router1`` will consider FaceUri
+``udp4://router3.arizona.edu`` for router ``/ndn/edu/arizona/%C1.Router/router3`` and face
+uri ``udp4://79.123.10.145`` for router ``/ndn/edu/colostate/%C1.Router/router2``.
+
+Step 3: Creating configuration file
+-----------------------------------
+
+Now, assume that ``/ndn/memphis.edu/router1`` wants to advertise three name prefixes
+(``/ndn/memphis/sports/basketball/grizzlies``, ``/ndn/memphis/entertainment/blues``,
+``/ndn/news/memphis/politics/lutherking``). The configuration file with the necessary
+configuration commands follows:
+
+::
+
+    ; nlsr.conf starts here
+    ; the general section contains all the general settings for router
+

+        prefix /ndn/memphis/sports/basketball/grizzlies
+        prefix /ndn/memphis/entertainment/blues
+        prefix /ndn/news/memphis/politics/lutherking
+    }
+
+.. note::
+
+    Security configuration is discussed in :doc:`SECURITY-CONFIG`, which will be also part
+    of this configuration file
+
+Step 4: Running NLSR on /ndn/memphis.edu/router1
+-------------------------------------------------
+
+Assuming the configuration file is saved as ``nlsr.conf``, type the following to run nlsr:
+
+::
+
+    $ nlsr -f nlsr.conf
+
+NLSR will look for nlsr.conf in the current directory. If nlsr.conf is not in the current
+directory, please provide the absolute path with the file name as the value. If
+``nlsr.conf`` resides in ``/home/ndnuser/configuration`` directory, type ``nlsr -f
+/home/ndnuser/configuration/nlsr.conf`` to run nlsr.
+
+The same process needs to be followed for ``/ndn/arizona.edu/router3`` and
+``/ndn/colostate.edu/router2`` to run NLSR on these routers.
+
+Expected Output
+----------------
+
+Assuming that all three routers are configured correctly and routing has converged, ``nfd-status`` in
+``/ndn/edu/colostate/%C1.Router/router2`` will have the following entries for the name
+advertised by ``/ndn/edu/memphis/%C1.Router/router1``:
+
+RIB:
+
+::
+
+    /ndn/memphis/entertainment/blues route={faceid=17 (origin=128 cost=25 ChildInherit), faceid=7 (origin=128 cost=58 ChildInherit)}
+    /ndn/memphis/sports/basketball/grizzlies route={faceid=17 (origin=128 cost=25 ChildInherit), faceid=7 (origin=128 cost=58 ChildInherit)}
+    /ndn/news/memphis/politics/lutherking route={faceid=17 (origin=128 cost=25 ChildInherit, faceid=7 (origin=128 cost=58 ChildInherit)}
+
+This output can be seen by typing ``nfd-status -r`` in the terminal.  Please refer to the
+network figure for face IDs.

+
+Certificate Publishing
+----------------------
+
+In a network, every router should have the root certificate configured as a trust
+anchor. For each site, at least one router should publish the site certificate, and at
+least one router should publish the certificate of the site operator. Each router should
+publish its own certificate. All this information should be explicitly specified in the
+nlsr.conf file. For example, the following configuration file indicates that NLSR should
+publish the site certificate and the router certificate:
+
+::
+
+    ...
+    security
+    {
+      validator
+      {
+        ...
+      }
+      cert-to-publish "site.cert"   ; name of the file which contains the site certificate (optional).
+      cert-to-publish "router.cert" ; name of the file which contains the router certificate (required).
+      ...
+    }

+NLSR - Named Data Link State Routing Protocol
+=============================================
+
+NLSR is a routing protocol in NDN that populates NDN's Routing Information Base. NLSR will
+continue to evolve alongside the Named Data Networking `protocol
+<http://named-data.net/doc/ndn-tlv/>`_.
+
+NLSR is an open and free software package licensed under the GPL 3.0 license and free to
+all Internet users and developers. For more information about the licensing details and
+limitations, refer to `COPYING.md
+<https://github.com/named-data/NLSR/blob/master/COPYING.md>`_.
+
+NLSR is developed by the members of the `NSF-sponsored NDN project team
+<http://named-data.net/project/participants/>`_. For more details, please refer to
+`AUTHORS.md <https://github.com/named-data/NLSR/blob/master/AUTHORS.md>`_. Bug reports and
+feedback are highly appreciated and can be made through the `NLSR Wiki`_.
+
+The main design goal of NLSR is to provide a routing protocol to populate NDN's FIB. NLSR
+calculates the routing table using link-state or hyperbolic routing and produces multiple
+faces for each reachable name prefix in a single authoritative domain. NLSR will continue
+to evolve over time to include neighbor discovery and to become a full fledged
+inter-domain routing protocol for NDN.  The project design is presented in full detail in
+the `NLSR Paper`_.

-\section{FIB Interaction}
-\label{sec:fib}
-
-The FIB module interacts with NFD to perform registrations and
-unregistrations of routes. By registration, what is meant is the
-submission of a RIB route to the local NFD, which includes a name
-prefix, the Face ID of the nexthop, an expiration time, and the
-calculated cost from the Routing Table calculation. Additionally, NLSR
-sets a field to tell NFD that the route originates from NLSR, and sets
-a route inheritance flag.
-
-The expiration time for a route is pegged at double the value of the
-LSA refresh time, which is defined by \texttt{lsa-refresh-time} in the
-configuration file. The route inheritance flag is set to capture,
-which forbids NFD from using a shorter prefix of the name prefix for
-forwarding.
-
-More information about NFD's RIB can be found on the
-\href{https://redmine.named-data.net/projects/nfd/wiki/RibMgmt}{Redmine
-  wiki}. An important thing to note is that NFD has a module called
-the FIB. Anywhere in this guide, the word ``FIB'' refers to the NLSR
-FIB, which models NLSR's expectation of how NFD would forward packets.
-
-The FIB is directed by the Name Prefix Table, which registers and
-unregisters routes based on calculations by the Routing Table and
-advertisements from LSAs. The connection between the FIB and the NPT
-is through the \texttt{Fib::update()} method.
-
-\subsection{Updating the FIB}
-Generally, updating the FIB looks like this:
-\begin{itemize}
-\item Sort the list of next hops for the prefix, by cost.
-\item Take the cheapest \texttt{max-faces-per-prefix} hops. This can be set to have no limit, so all next hops are registered.
-\item Send a RIB route registration command for each next hop.
-\item Send a RIB route unregistration command for any next hops that
-  have dropped out of the list. This includes next hops that became
-  invalid since the last Routing Table calculation, as well as valid
-  hops that are no longer in the top \texttt{max-faces-per-prefix}
-  next hops.
-\end{itemize}
-
-If there are more passed next hops than the
-\texttt{max-faces-per-prefix}, the FIB module will only use the first
-\texttt{max-faces-per-prefix} number of next hops from the sorted
-list.  If there are less passed next hops than
-\texttt{max-faces-per-prefix}, the FIB module will use all of the next hops.
-Specifically, when the NPT updates the FIB, the FIB creates entries so
-that it can compute the difference between the set of new next hops,
-and the set of old next hops that were registered at the last update.
-These entries are unique on the destination name prefix. The FIB will
-update an existing entry instead of creating a new one, which may
-involve unregistering old next hops, as mentioned above.

-The Hello Protocol module periodically sends Hello Interests to learn the activity status of the router's neighbors.
-Hello Interests' names are constructed in the form: \texttt{/<neighbor's-router-prefix>/NLSR/INFO/<this-router's-prefix>}.
-If a neighbor responds to a Hello Interest, the neighbor is considered to be up and \texttt{ACTIVE}.
-A Hello Data's name is constructed using the following convention: \texttt{/<neighbor's-router-prefix>/NLSR/INFO/<this-router's-prefix>/<version>}.
-If a neighbor fails to respond to a configurable number of Hello Interests (\texttt{hello-retries}), the neighbors is considered to be down and \texttt{INACTIVE}.
-The Hello Protocol continues to send these periodic Hello Interests to each of its neighbors every \texttt{hello-interval} seconds.
-If the Hello Protocol detects a change in a neighbors status
-(i.e. a router that was previously \texttt{ACTIVE} is not responding to Hello Interests or a router that was previously \texttt{INACTIVE} responds to a Hello Interest),
-it will notify the LSDB (Section~\ref{sec:lsdb}) to schedule a new Adjacency LSA build to include the updated neighbor information.

-\caption{Router A determines the initial status of Router B}
-\end{figure}
-
-The Hello Protocol begins by scheduling Hello Interests to be sent to each neighbor of the router after \texttt{first-hello-interval} seconds.
-When the scheduled event is triggered, the Hello Protocol iterates through the list of neighbors first checking if there is already a Face to the neighbor.
-If there is a Face that has already been created, the Hello Protocol will construct and send a Hello Interest to the neighbor.
-If a Face has not been created for the neighbor, the Hello Protocol will attempt to create a Face to the neighbor and register the neighbor's router prefix.
-If the Face is created successfully, the Hello Protocol registers the Sync prefix, LSA prefix, and Key prefix using the Face ID returned by the Face creation command and sends out the Hello Interest.
-If the Face cannot be created, the Hello Protocol considers the failure as a Hello Interest timeout.
-
-If the Hello Protocol receives Data in response to its Hello Interest, it will first ask the Validator module to verify that the Data is valid. Data is valid if the Data is legitimately signed (in the ordinary cryptographic way) and if the key name and Data name are of a certain format.
-If the Data is valid, the corresponding neighbor is set as \texttt{ACTIVE} and its timeout count is reset to zero.
-If the neighbor was previously \texttt{INACTIVE}, an Adjacency LSA build is scheduled to include the newly \texttt{ACTIVE} neighbor.
-If the Data is not valid, the packet is dropped.
-
-If the Hello Interest sent to the neighbor times out, the corresponding neighbor's timed-out count is incremented.
-If the neighbor's timed-out count is less than \texttt{hello-retries} in the configuration file, the Hello Protocol will send another Hello Interest after \texttt{hello-timeout} seconds.
-If the neighbor's timed-out count equals the \texttt{hello-retries} value and the neighbor is currently marked as \texttt{ACTIVE}, the neighbor's status is set to \texttt{INACTIVE} and an Adjacency LSA build is scheduled.
-
-\subsection{Responding to Hello Interests}
-\label{sec:respond-to-hello}
-
-If the Hello Protocol receives a Hello Interest from another router, it will first verify that the Hello Interest came from one of its configured neighbors.
-If so, the Hello Protocol responds to the Interest with Hello Data.
-To optimize the time to respond to link recoveries, the Hello Protocol will then immediately send a Hello Interest to the neighbor if the neighbor is currently marked as \texttt{INACTIVE}.
-
-\subsection{Failure and Recovery Detection}

-
-\begin{figure}
-\center
-\includegraphics[width=0.5\textwidth]{figures/hello-protocol-timeout}
-\caption{Router A determines that Router B has failed}
-\end{figure}
-
-The Hello Protocol will consider a neighbor as failed if the neighbor is currently \texttt{ACTIVE}, but Hello Interests sent to the neighbor have timed-out \texttt{hello-retries} number of times.
-A failure can also be detected if a FaceEventNotification is received with the information that a Face to the neighbor has been destroyed.
-The event is handled by the \texttt{Nlsr} class, but the triggered events simulate the actions of the Hello Protocol.
-If the neighbor was currently \texttt{ACTIVE}, the neighbor will be set to \texttt{INACTIVE}, the neighbor's timed-out count will be set to \texttt{hello-retries}, and an Adjacency LSA build will be scheduled.
-
-The Hello Protocol will consider a neighbor as recovered if the neighbor is currently \texttt{INACTIVE}, but the Hello Protocol has received valid Data in response to a Hello Interest sent to the neighbor.

-\section{Introduction}
-\label{sec:intro}
-
-The Named-data Link State Routing protocol (NLSR) is an intra-domain routing protocol for Named Data Networking (NDN).
-It is an application level protocol similar to many IP routing protocols, but NLSR uses NDN's Interest/Data packets to disseminate routing updates.
-Although NLSR is designed in the context of a single domain, its design patterns may offer a useful reference for future development of inter-domain routing protocols.
-
-NLSR supports name-based routing in NDN, computes routing ranks for all policy-compliant next-hops which provides a name-based multi-path routing table for NDN's forwarding strategy,
-and ensures that routers can originate only their own routing updates using a hierarchical trust model.
-
-\subsection{NLSR Modules and Data Structures}
-\label{sec:modules}
-NLSR contains multiple modules that each contribute to the total realization of the protocol.
-Many of the modules interact with one another to trigger some behavior or to modify information in data structures.
-NLSR uses the following modules:
-\begin{itemize}
-\item \textbf{Hello Protocol} (Section~\ref{sec:hello-protocol}) - determines the status of neighboring routers using periodic Hello Interests and notifies other modules when neighbors' statuses change.
-\item \textbf{ChronoSync} - provides network-wide synchronization of NLSR LSDBs.~\cite{chronosync}
-\item \textbf{Sync Logic Handler} (Section~\ref{sec:sync-logic}) - handles sync update notifications from NSync by retrieving updated LSAs.
-\item \textbf{LSAs} (Section~\ref{sec:lsas}) - represent routing information published by the router.
-\item \textbf{LSDB} (Section~\ref{sec:lsdb}) - stores the LSA information distributed by other routers in the network.
-\item \textbf{Routing Table} (Section~\ref{sec:routing-table}) - calculates and maintains a list of next hops for each router in the network.
-\item \textbf{Name Prefix Table} (Section~\ref{sec:npt}) - stores all advertised name prefixes and their next hops.
-\item \textbf{FIB} (Section~\ref{sec:fib}) - maintains a shadow FIB which represents the intended state of NFD's FIB~\cite{NFD}.
-\item \textbf{Prefix Update Processor} (Section~\ref{sec:prefix-update}) - listens for dynamic prefix announcements to advertise or withdraw name prefixes.
-\item \textbf{NFD RIB Command Processor} (Section~\ref{sec:nfd-rib-commands}) - listens for readvertise-to-NLSR commands to advertise or withdraw name prefixes that were inserted into NFD.
-\end{itemize}
-
-\subsection{Protocol Overview}
-\label{sec:protocol-overview}
-
-NLSR is designed to accomplish three main tasks: (1) discover adjacent
-neighbors; (2) disseminate and synchronize topology, name prefix, and
-hyperbolic routing information; and (3) calculate a routing table and
-populate NFD's FIB.  The entire protocol is described in detail in the
-NLSR paper~\cite{NlsrTr}.
-
-\subsubsection{Discovering Neighbors}
-
-NLSR determines the adjacency status of neighboring routers using the Hello Protocol module (Section~\ref{sec:hello-protocol}).
-When the Hello Protocol detects a status change for a neighbor, it will ask the LSDB module (Section~\ref{sec:lsdb}) to update the router's advertised adjacency information.
-
-Additionally, NLSR discovers the infrastructure for communicating with
-neighbors by querying NFD, which maintains a dataset of all
-information for its Faces.
-
-\subsubsection{Disseminating Routing Information}
-
-When a router's LSAs (Section~\ref{sec:lsas}) changes, the information of this change should be distributed to every other router in the network.
-The Sync Logic Handler module (Section~\ref{sec:sync-logic}) is used to notify the synchronization protocol of changes to the router's own LSAs as well as to learn of LSA changes from other routers in the network;
-the Sync Logic Handler module interfaces with ChronoSync to perform the two tasks.
-
-When the Sync Logic Handler module learns of a new LSA, it will inform the LSDB module.
-The LSDB module will attempt to fetch the new LSA and will store it in the LSDB module's database if it can be retrieved.
-If the newly fetched LSA informs the router of previously unknown routing information, the LSDB module will inform other modules depending on the type of routing information:
-\begin{itemize}
-  \item \textbf{Change in network topology} - the LSDB module will ask the Routing Table module (Section~\ref{sec:routing-table}) to recalculate paths in the network
-\item \textbf{Change in name prefix advertisement} - the LSDB module will inform the Name Prefix Table module (Section~\ref{sec:npt}), which will in turn notify the FIB module (Section~\ref{sec:fib}) in order to add or remove the changed name prefixes.
-\item \textbf{Change in hyperbolic coordinates} - the LSDB module will inform the Routing Table module (Section~\ref{sec:routing-table}), so the Routing Table module can calculate an up-to-date routing table.
-\end{itemize}
-
-\subsubsection{Calculating the Routing Table and Populating NFD's FIB}
-
-When the routing table is calculated by the Routing Table module, the computed next hops are passed to the Name Prefix Table module.
-The Name Prefix Table module will then further pass the next hops to the FIB module to update NLSR's expected state of NFD's FIB.
-The FIB module will then perform the registrations or unregistrations with NFD's FIB.\\
-
-A simplified diagram of NLSR's actions when receiving new routing information is shown in Figure~\ref{fig:system-interaction}.
-The remainder of this documentation will describe the purpose of and interaction between each module in more detail.

-\end{figure}

-\subsection{Dispatcher}
-\label{sec:dispatcher}
-
-NLSR takes advantage of a variety of ndn-cxx convenience
-mechanisms. Among these is the dispatcher. The dispatcher provides
-facilities for receiving and decoding ControlCommands, which
-simplifies the processing workflow. The dispatcher itself is
-\href{http://named-data.net/doc/ndn-cxx/current/doxygen/de/d34/classndn_1_1mgmt_1_1Dispatcher.html}{well-documented},
-so we will only give a brief overview here.
-
-\begin{itemize}
-\item Any prefixes that are registered, such as ``prefix/register'',
-  \emph{must} be registered before top-level prefixes. All prefix
-  registrations should go in \texttt{Nlsr::registerLocalhostPrefix}.
-\item The dispatcher can be used to accept incoming ControlCommands
-  and respond to requests for datasets. Currently NLSR uses the
-  dispatcher only for accepting incoming ControlCommands.
-\item Top-level prefixes cannot overlap. For example, you cannot
-  register ``/localhost/nlsr'' and then ``/localhost/nlsr/fib''. The
-  second registration must be done as a sub-prefix of the first,
-  i.e. the first prefix, and then ``fib''.

-\section{Link-State Advertisements}
-\label{sec:lsas}
-
-Link-State Advertisements (LSAs) represent pieces of routing information distributed by routers.
-
-\subsection{LSA Base Class}
-\label{sec:lsa-base-class}
-
-All three LSA implementations inherit from an LSA Base class, \texttt{Lsa}, which maintains information that is included in each LSA.
-The \texttt{LSA} class contains the following member variables:
-\begin{itemize}
-\item \textbf{Origin Router} - the router that advertised the LSA. Specifically, this is a name prefix that follows the NLSR convention of router naming.
-\item \textbf{Sequence Number} - a number used to indicate the LSA's version. Because sequence numbers are preserved between NLSR restarts, a higher sequence number also always indicates a \emph{newer} LSA.
-\item \textbf{Expiration Time Point} - a time point indicating when the LSA is no longer valid. This currently is represented as a Unix timestamp (i.e. seconds since Jan 1, 1970).
-\end{itemize}
-
-\subsection{Adjacency LSAs}
-\label{sec:adjacency-lsas}
-
-Adjacency LSAs maintain an \texttt{AdjacencyList} which contains information about all the currently \texttt{ACTIVE} neighbors of the origin router. It also includes the number of active routers, not just the list itself. This aids in serialization.
-
-\subsection{Coordinate LSAs}
-\label{sec:coordinate-lsas}
-
-Coordinate LSAs maintain the hyperbolic angle(s) and hyperbolic radius of the origin router.
-
-\subsection{Name LSAs}
-\label{sec:name-lsas}
-
-Name LSAs maintain a \texttt{NamePrefixList} which contains the name prefixes that are reachable at the origin router.

-\section{LSDB Status Dataset}
-\label{sec:lsdb-status-dataset}
-
-NLSR makes available the entire contents of the LSDB upon request. A
-command can request LSAs of just a specific type, or request the
-collection of all LSAs. Unlike the Prefix Update and NFD RIB command
-processors, the LSDB Status dataset is available over \emph{both} the
-\texttt{/localhost} and regular router prefixes. That is, you can
-request an arbitrary router's LSDB contents.
-
-\subsection{Requesting the dataset}
-\begin{itemize}
-\item To request the local dataset, simply send an Interest of the
-  form \texttt{/localhost/nlsr/lsdb/<dataset type>}.
-\item To request a remote dataset, send an Interest of the form
-  \texttt{/<router name>/lsdb/<dataset type>}, where \texttt{<router
-    name>} is whatever the router's name is. This is usually
-  \texttt{general.network + general.site + general.router} from the
-  configuration file.
-\end{itemize}
-
-Where \texttt{<dataset type>} is one of \texttt{names, adjacencies, coordinates} or \texttt{list}.

-\section{Link-State Database}
-\label{sec:lsdb}
-
-The Link-State Database (LSDB) holds LSA information distributed by
-other routers in the network.  The LSDB stores all types of LSAs and
-will trigger events when a new LSA is added, updated, or expires.  The
-LSDB also handles LSA retrieval, performs LSA builds, and triggers
-routing table calculations.
-
-\subsection{Retrieving an LSA}
-
-The LSDB provides the \texttt{Lsdb::expressInterest()} method as a
-public interface to retrieve an LSA from the network.  If LSA Data is
-returned, the LSDB will validate the Data using the Validator
-module. Then, it will perform the necessary LSDB modifications.  If
-the LSA Interest times out, the LSDB will retry until it reaches a
-configurable maximum number of tries, or a configurable deadline
-passes.
-
-The LSDB uses the SegmentFetcher system to retrieve LSAs. LSAs very
-often will exceed the maximum NDN packet size. In these cases, the LSA
-needs to be split into segments to be sent, so the LSDB uses the
-SegmentFetcher to send all LSAs. The SegmentFetcher can decide if the
-data actually needs to be split.
-
-\subsection{General Procedure}
-
-The LSDB is responsible for building, installing, and publishing
-NLSR's LSAs, as well as for installing and processing LSAs from other
-NSLRs. Generally, the functions of the LSDB are:
-\begin{itemize}
-\item Schedule the building of an LSA.
-\item Building the LSA.
-\item Installing the LSA into the LSDB.
-\end{itemize}
-
-\subsection{Scheduling LSA Builds}
-LSAs need to be rebuilt whenever the routing information NLSR has
-changes. This includes events like neighbors becoming active, or when
-a prefix for advertisement is inserted by the Prefix Update Processor,
-which would cause an adjacency LSA or a name LSA rebuild,
-respectively. To improve performance, instead of directly building
-adjacency LSAs the first request schedules the build, and build requests
-that occur after the scheduling but before the actual event are
-aggregated (in other words, ignored), because they will be satisfied
-by the already-scheduled build. Some specifics are shown below.
-below.
-\begin{itemize}
-\item \textbf{Adjacency LSAs} -- will only be scheduled if link-state
-  routing is enabled. In particular, this means Adjacency LSA builds
-  will \emph{not} occur if hyperbolic routing is enabled. Note that
-  adjacency LSAs will be built if dry-run hyperbolic routing is
-  enabled, as the network is still using link-state routing to
-  calculate paths.
-\end{itemize}
-
-\subsection{Building LSAs}
-Building LSAs has a part common to all LSAs and a part specific to
-each LSA type. For example, all LSA types increment sequence number
-and have the same expiration length, and of course come from the same
-router. Additionally, all LSA builds cause a sync update
-publishing. However, each type of LSA includes different data, to
-represent different kinds of information that NLSR
-has. (Section~\ref{sec:lsas}) In particular:
-\begin{itemize}
-  \item \textbf{Adjacency LSAs} -- the number and a list of active
-    neighbors is included.
-  \item \textbf{Coordinate LSAs} -- the hyperbolic radius and all
-    hyperbolic angles are included.
-  \item \textbf{Name LSAs} -- the list of name prefixes that are
-    accessible at this router is included.
-\end{itemize}
-
-\subsection{Installing and Processing LSAs}
-LSA installation procedure is mostly the same across any type of LSA,
-but each type also has installation behavior specific to that type,
-too. For any LSA type, we need to schedule an expiration event, and we
-need to update several fields in the LSA. However, installing an
-adjacency or coordinate LSA causes a Routing Table calculation, but a
-name LSA does not, for example.
-%%| Not yet true, but it should be true!
-Additionally, the name of the origin router is added as a ``routable prefix'' in the NPT. (Section~\ref{sec:npt}).
-\begin{itemize}
-  \item \textbf{Adjacency LSAs} -- each adjacency in the LSA will be
-    added as a ``routable prefix'' to the NPT. If the adjacencies have
-    changed since the last version of this LSA, a Routing Table
-    calculation needs to be scheduled, because the state of the
-    network has changed. Of course, this is necessarily true if the
-    LSA is new to us. Important to note is that we will also install
-    and process \emph{our own} adjacency LSA in this way.
-  \item \textbf{Coordinate LSAs} -- the router that the LSA is from
-    will be added as a ``routable prefix'' to the NPT. If the radius
-    and coordinates have changed since the last version of this LSA, a
-    Routing Table calculation needs to be scheduled, because the state
-    of the network has changed. As above, this is true for a new
-    LSA. This is only done if the LSA is from a foreign router.
-  \item \textbf{Name LSAs} -- each name prefix in the LSA will be
-    added to our NPT. This is only done if the LSA is from a foreign
-    router.
-\end{itemize}
-
-\subsection{LSA Expiration}
-LSAs expire so that the network can clean up when a router
-crashes. The amount of time an LSA lasts is configurable. When an LSA
-expires, we refresh it if it's our LSA, and remove it from the LSDB if
-not. There is a ``grace period'' window that is appended to the end of
-the expiration period of all LSAs, to provide time for the originating
-router to refresh the LSA and for it to propagate back to us. In all
-expiration cases, the name of the origin router will be removed from
-the NPT. What happens when an LSA is removed from the LSDB differs
-based on the type of LSA:
-\begin{itemize}
-  \item \textbf{Adjacency LSAs} -- a Routing Table calculation needs to occur,
-    since the state of the network has changed, at least from our
-    perspective.
-  \item \textbf{Coordinate LSAs} -- a Routing Table calculation needs to occur,
-    since the state of the network has changed, at least from our
-    perspective.
-  \item \textbf{Name LSAs} -- the name prefixes in the LSA are removed from the
-    NPT.
-\end{itemize}
-
-\subsection{LSA Refreshment}
-NLSR will only refresh its own LSAs. Additionally, the procedure for refreshing an LSA is the same for all types:
-\begin{itemize}
-\item Increment the LSA sequence number
-\item Schedule another expiration event. The length of time to wait
-  until refreshing is configurable, but it should probably be lower
-  than the expiration time that was set when building the LSA
-  initially. This prevents other routers from deleting our LSAs
-  because the network is slow, for instance. The length of time is set
-  by \texttt{lsa-refresh-time} in the configuration file.
-\item Publish an update to sync
-\end{itemize}

-
-The NFD RIB Command Processor allows modification of NLSR's advertised
-name prefixes using NFD's RibMgmt commands. Such commands may

-routes inserted in NFD to be propagated through to NLSR, so that NLSR
-can provide routing support for them.

-\subsection{Advertising and Withdrawing Routes}
-The processor accepts valid RibMgmt commands that have the name prefix
-to manipulate the origin of the route specified. No other validation
-is performed, as stated below.
-
-The processor does not send any kind of response to commands.
-
-\subsection{Security}
-Any RibMgmt commands received on the \texttt{/localhost/nlsr/rib}
-prefix are considered secure, and are processed. This introduces a
-security hole because anyone who can send a RibMgmt command on this
-prefix can arbitrarily manipulate NLSR's advertised prefixes. However,
-because sending commands to this prefix requires root access, a
-would-be attacker will already have root access locally.

-The Named Data Link-State Routing Protocol (NLSR) is a Named Data Networking (NDN) routing protocol that populates NDN Forwarding Daemon's (NFD) Routing Information Base (RIB).
-The main design goal of NLSR is to provide a routing protocol to populate NFD's RIB and Forwarding Information Base (FIB).
-NLSR calculates the routing table using link-state or hyperbolic routing and produces multiple faces for each reachable name prefix in a single authoritative domain.
-NLSR will continue to evolve alongside the NDN protocol, NFD, and ndn-cxx.
-This document is meant to explain the design of NLSR including major module and data structures descriptions and the interactions between those components.

-    A diagram of the NPT and Routing Table.

-      The ``wire'' arrows represent references (i.e. ``x has y''),
-      whereas the ``solid'' arrows represent inheritance (i.e. ``y subclasses x''). \\

-\end{figure}
-
-The Name Prefix Table (NPT) is used by NLSR to maintain a list of all known name prefixes advertised by other routers, including router names.
-The NPT maintains a collection of NPT entries, where each entry represents a name prefix and all of its associated routing table entries.
-Additionally, to optimize the storage and association of the routing table entries, the NPT also maintains a collection of duplicated routing table entries, called routing table pool entries, which have an additional use count attribute.
-The NPT entries keep shared pointers to the appropriate routing table pool entries.
-If a name prefix is advertised by multiple routers, the name prefix will be represented by only one Name Prefix Table Entry, but will have multiple routing table pool entries  which correspond with each origin router.
-
-If a Name LSA exists with some advertised name prefix, then that prefix must have an entry in the NPT. So, if two routers advertise the same name prefix, i.e. their name LSAs contain a common name prefix, even if one router withdraws that common name prefix, the entry must remain in the NPT, because the other router still advertises it.
-
-If any type of LSA for a remote router exists in the LSDB, the remote router's name prefix must be in the NPT.
-An NPT Entry for a router name can only be removed when there are no more LSAs in the LSDB from the origin router. Note, even if some NPT entry nas no next hops, it will \emph{not} be removed from the NPT; it may later become possible to route to this prefix. These prefixes will be removed from the FIB, however.
-
-\subsection{Adding an NPT Entry}
-\label{sec:npt-add}
-The \texttt{NamePrefixTable::addEntry()} method is the public
-interface for name prefixes to be added to the NPT.
-The name prefix as well as the router's prefix which originates the
-name prefix are passed as parameters to the method.
-
-If the name prefix is new, there will be no NPT entry for it, so one
-will be created. If the name prefix is not new, the existing entry
-will be updated, so the existing entry will also store this new origin
-router's prefix, too. If after updating, the NPT entry has any next
-hops, which are associated to each of the origin router prefixes, the
-NPT will update the FIB to include that prefix and its next hops. The
-next hop list is sorted and truncated to be only as long as the
-\texttt{max-faces-per-prefix} variable.
-n
-\subsection{Removing an NPT Entry}
-\label{sec:npt-del}
-The \texttt{NamePrefixTable::removeEntry()} method is the public
-interface for name prefixes to be removed from the NPT.
-The name prefix as well as the router's prefix which originates the
-name prefix are passed as parameters to the interface.
-
-This method removes an origin router prefix from some advertised name
-prefix. After this, there may be other origin routers that serve this
-name prefix, so this does not guarantee that the NPT entry will be
-deleted. If after updating the entry has any next hops, the NPT will
-update the FIB to reflect the change. Since the next hop list is
-sorted by ascending cost and its length truncated to
-\texttt{max-faces-per-prefix}, the contents of next hop list will not
-change if the removed origin router prefix was not already in the list
-passed to the FIB.
-
-Note that even if the entry no longer has any next hops, it will be retained. All FIB entries for this prefix will be removed from the FIB, which will result in unregistrations from NFD, but the NPT entry will be retained. This is because it may become possible later to route to these origin routers again.
-
-\subsection{Updating an NPT Entry with New Routing Table Entries}
-\label{sec:npt-update-with-new-route}
-When the Routing Table module has finished calculating, it will notify
-the NPT using the \texttt{NamePrefixTable::updateWithNewRoute()}
-method.
-The NPT will then make approximately $m \times n$ calls to
-\texttt{addEntry}, where $m$ is the number of NPT entries and $n$ is
-the number of origin routers for each m. That is, $n$ will vary from
-one NPT entry to the next in most cases.
-
-\subsection{Routing Table Entry Pool}
-The Name Prefix Table has an internal data structure to help
-de-duplicate Routing Table information. Without this, each Routing
-Table entry has to be stored $n$ times, if $n$ is the number of
-prefixes that origin router advertises. Instead, each time a Routing
-Table entry would be fetched, the NPT first checks its internal data
-structure to see if that Routing Table entry is being used by another
-NPT entry. In that case those two NPT entries can share a pointer to
-that cached copy of the Routing Table entry.
-
-This internal cache is smart, and will clean up from the cache unused
-entries when they are removed from the last NPT entry.
