NFD version 0.4.0
|
|
-----------------
|
|
|
|
Release date: TBD
|
|
|
|
.. note::
|
|
Version 0.4.0 introduces several breaking changes to API and wire format of management protocols
|
|
|
|
Changes since version 0.3.4:
|
|
|
|
New features:
|
|
^^^^^^^^^^^^^
|
|
|
|
- **(breaking change)** Refactored implementation of face system (:issue:`3088`,
|
|
:issue:`3104`, :issue:`3165`, :issue:`3168`, :issue:`3225`, :issue:`3226`, :issue:`3253`)
|
|
|
|
The abstraction to send/receive NDN packets has been split into Transport, LinkService, and Face:
|
|
|
|
* *Transport* provides delivery of the data blocks over specific underlying channels
|
|
(raw ethernet packets, unicast/multicast UDP datagrams, TCP and WebSocket streams)
|
|
|
|
Implemented: :NFD:`UnixStreamTransport`, :NFD:`UnicastUdpTransport`, :NFD:`MulticastUdpTransport`,
|
|
:NFD:`InternalForwarderTransport`
|
|
|
|
* *LinkService* provides an "adaptation" layer to translate between NDN packets and data
|
|
blocks communicated through Transport. For example, LinkService can provide packet
|
|
fragmentation and reassembly services.
|
|
|
|
Implemented: :NFD:`GenericLinkService`
|
|
|
|
* *Face* provides combines Transport and LinkServices, providing high-level interface to work
|
|
with Interest/Data/Nack packets inside NFD.
|
|
|
|
.. note::
|
|
This feature replaces support for signaling between local applications and NFD from
|
|
LocalControlHeader with NDNLPv2 protocol. If your application uses
|
|
LocalControlHeader features, it must be updated to use the new protocol (e.g., update
|
|
to use ndn-cxx >= 0.4.0)
|
|
|
|
- Support for NDNLPv2 (http://redmine.named-data.net/projects/nfd/wiki/NDNLPv2,
|
|
:issue:`2520`, :issue:`2763`, :issue:`2841`)
|
|
|
|
* Network NACK (:issue:`2883`)
|
|
|
|
- Networking NACK in pipelines and best-route strategy (:issue:`3156`)
|
|
|
|
- Refactored implementation of NFD management (:issue:`2200`, :issue:`2107`)
|
|
|
|
- Interest forwarding processes Link included in interest packets (:issue:`3034`)
|
|
|
|
.. note::
|
|
This feature requires proper defintion of new ``tables.network_region`` section in
|
|
the NFD config file (:issue:`3159`)
|
|
|
|
- Full support for UDP permanent faces (:issue:`2993`, :issue:`2989`, :issue:`3018`)
|
|
|
|
Updates and bug fixes:
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- **(breaking change)** Redesign of automatic prefix propagation, formerly known as remote
|
|
prefix registration (:issue:`3211`, :issue:`2413`)
|
|
|
|
This includes a backward-incompatible change to NFD's configuration file:
|
|
|
|
* ``rib.remote_register`` section has been removed and, if present, will cause failure for NFD to start
|
|
* ``rib.auto_prefix_propagate`` section has been added to control automatic prefix propagation feature
|
|
|
|
- Fix memory leak in PriorityFifoPolicy (:issue:`3236`)
|
|
|
|
- Display extended information for fatal NFD errors (:issue:`2541`)
|
|
|
|
- Compilation fixes for clang-700.0.72 (Apple LLVM 7.0.0) (:issue:`3209`)
|
|
|
|
- Properly handle exception from NetworkMonitor when the platform doesn't support it
|
|
(:issue:`3195`)
|
|
|
|
Deprecated:
|
|
^^^^^^^^^^^
|
|
|
|
- BroadcastStrategy (``/localhost/nfd/strategy/broadcast``) renamed as MulticastStrategy
|
|
(``/localhost/nfd/strategy/multicast``) (:issue:`3011`)
|
|
|
|
Deleted:
|
|
^^^^^^^^
|
|
|
|
- NotificationStream, replaced by the version in ndn-cxx library (:issue:`2144`)
|
|
|
|
|
|
Planned features for future releases:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- Improvements and extension of NDNLPv2 support
|
|
|
|
* New transports
|
|
* New link service implementation, including support for fragmentation and assembly
|
|
|
|
- Improved support for automatic prefix propagation (:issue:`3211`, :issue:`2413`)
