Mini-NDN Installation Instructions
|
||||
================================
|
||||
|
||||
### What equipment will I need?
|
||||
|
||||
For this guide, you will need a laptop/desktop with a recent version
|
||||
of a Linux distro such as Ubuntu or any of its variants. Fedora is not
|
||||
officially supported but has also been reported to work for some
|
||||
users. For this guide, the _Ubuntu 18.04 LTS_ release was used.
|
||||
Also, note that you'll need administrative privileges in order to
|
||||
download and install extra packages and also to execute **Mini-NDN**.
|
||||
|
||||
### Installing **Mini-NDN**
|
||||
|
||||
NOTE: Mini-NDN, while providing a high level of emulation of hosts,
|
||||
requires programs to be installed onto your computer. It will not work
|
||||
if they are not installed. If you do not want NDN software installed
|
||||
onto your computer, you can use a virtual machine, which can be quite
|
||||
simply set up with the provided vagrantfile.
|
||||
|
||||
If you have all the dependencies (see sections below) installed simply clone this repository and run:
|
||||
|
||||
./install.sh -i
|
||||
|
||||
else if you don't have the dependencies, the following command will install them from source along with Mini-NDN:
|
||||
|
||||
./install.sh -a
|
||||
|
||||
If you want to install the dependencies manually or from the Named Data PPA, follow the instructions below:
|
||||
|
||||
### Installing NDN
|
||||
|
||||
Each node in **Mini-NDN** will run the official implementation of NDN installed on your system. The following dependencies are needed:
|
||||
|
||||
Mini-NDN uses NFD, NLSR, and ndn-tools.
|
||||
|
||||
To install NFD:
|
||||
https://named-data.net/doc/NFD/current/INSTALL.html
|
||||
|
||||
To install NLSR:
|
||||
https://named-data.net/doc/NLSR/current/INSTALL.html
|
||||
|
||||
To install ndn-tools:
|
||||
https://github.com/named-data/ndn-tools
|
||||
|
||||
Note that all three of these can be installed from the Named Data PPA. Instructions for setting it up can
|
||||
be found in the NFD insallation instructions. Note that PPA and installs from source **cannot** be mixed.
|
||||
|
||||
###Special Instructions for PPA Installs
|
||||
|
||||
If you are using a custom nfd.conf file in an experiment, you should place it in /usr/local/etc/ndn/
|
||||
rather than /etc/ndn/. This is to avoid a bug from the default configuration file for the PPA, which
|
||||
is incompatiable with Mini-NDN.
|
||||
|
||||
### Installing Mininet
|
||||
|
||||
**Mini-NDN** is based on Mininet. To install Mininet:
|
||||
|
||||
First, clone Mininet from github:
|
||||
|
||||
git clone --depth 1 https://github.com/mininet/mininet.git
|
||||
|
||||
After Mininet source is on your system, run the following command to
|
||||
install Mininet core dependencies and Open vSwitch:
|
||||
|
||||
./util/install.sh -nv
|
||||
|
||||
To check if Mininet is working correctly, run this test:
|
||||
|
||||
sudo mn --test pingall
|
||||
|
||||
This will print out a series of statements that show the test setup
|
||||
and the results of the test. Look for `Results:` two-thirds of the way
|
||||
down where it will indicate the percentage of dropped packets.
|
||||
Your results should show "0% dropped (2/2 received)".
|
||||
|
||||
### Installing Infoedit
|
||||
|
||||
Infoedit is used to edit configuration files such as NFD configuration
|
||||
file.
|
||||
|
||||
To install infoedit:
|
||||
https://github.com/NDN-Routing/infoedit
|
||||
|
||||
### Verification
|
||||
|
||||
You can use these steps to verify your installation:
|
||||
|
||||
1. Issue the command: `sudo minindn --experiment=pingall --nPings=50`
|
||||
2. When the `mini-ndn>` CLI prompt appears, the experiment has finished. On the Mini-NDN CLI, issue the command `exit` to exit the experiment.
|
||||
3. Issue the command: `grep -c content /tmp/minindn/*/ping-data/*.txt`. Each file should report a count of 50.
|
||||
4. Issue the command: `grep -c timeout /tmp/minindn/*/ping-data/*.txt`. Each file should report a count of 0.

research on the NDN platform. Based on [Mini-CCNx](https://github.com/chesteve/mn-ccnx) which
|
||||
is a fork of [Mininet](https://github.com/mininet/mininet), Mini-NDN uses the NDN libraries,

Mini-NDN cluster edition
|
||||
========================
|
||||
|
||||
Mini-NDN cluster edition uses the experimental Mininet cluster edition.
|
||||
**Make sure that you can run the Mininet cluster edition by following
|
||||
[these instructions](https://github.com/mininet/mininet/wiki/Cluster-Edition-Prototype)**.
|
||||
Mini-NDN will use the "mininet" username created in Mininet cluster edition setup.
|
||||
|
||||
## Mini-NDN cluster options
|
||||
|
||||
To run Mini-NDN cluster on `localhost` and another server `server1` with
|
||||
the guided node placement strategy (default), the following command can be used:
|
||||
|
||||
sudo minindn --cluster=localhost,server1 --place-list=1,3
|
||||
|
||||
Note that `place-list` specifies the number of nodes to be placed on the corresponding servers
|
||||
of the cluster.
|
||||
In the example, one node will be placed on `localhost` and three nodes on `server1`.
|
||||
Unless specified, the default 4 node topology is used.
|
||||
Another placement can be `roundRobin` placement algorithm from Mininet.
|
||||
This does not require a place-list.
|
||||
|
||||
sudo minindn --cluster=localhost,server1 --placement roundRobin
|
||||
|
||||
By default the tunnel type used is SSH, but GRE tunnel can be specified by `--tunnel-type=gre`

|
||||
Configuration
|
||||
=============
|
||||
|
||||
Mini-NDN uses a configuration file describing the topology and its parameters to setup a network.
|
||||
It can be generated by the GUI or written by hand or scripts.
|
||||
|
||||
## Configuration file format:
|
||||
|
||||
### The [nodes] section:
|
||||
|
||||
At the bare minimum, the node section describes the nodes present in the topology.
|
||||
|
||||
[nodes]
|
||||
a: _
|
||||
b: _
|
||||
|
||||
Additionally each node can take the following parameters:
|
||||
|
||||
* app : Default application(s) to be started on a node (specify '_' if no app needs to be started - required).
|
||||
The app is the only parameter which needs double quotes (see example below).
|
||||
|
||||
* cpu : Amount of cpu available to a node (0.00 - 1.00), optional
|
||||
|
||||
* mem : Amount of memory available to a node in KB
|
||||
|
||||
* cache : Amount of cache memory available to a node in KB
|
||||
|
||||
* nfd-log-level: Set the log level of the NFD running on the node (ex: DEBUG). For finer control,
|
||||
nfd.conf or nfd.conf.sample needs to be modified in /usr/local/etc/ndn/
|
||||
|
||||
* nlsr-log-level: Set the log level of the NLSR running on the node (ex: DEBUG).
|
||||
|
||||
e.g.)
|
||||
|
||||
[nodes]
|
||||
a: _ cpu=0.3 nfd-log-level=TRACE nlsr-log-level=NONE
|
||||
b: app="sample app 1; sampleapp2.sh" cpu=0.3
|
||||
|
||||
### The [links] section:
|
||||
|
||||
The links section describes the links in the topology.
|
||||
|
||||
e.g.)
|
||||
|
||||
[links]
|
||||
a:b delay=10ms
|
||||
|
||||
This would create a link between a and b. 'b:a' would also result in the same.
|
||||
The following parameters can be configured for a node:
|
||||
|
||||
* delay : Delay parameter is a required parameter which defines the delay of the link (1-1000ms)
|
||||
|
||||
* bw : Bandwidth of a link (<1-1000> Mbps)
|
||||
|
||||
* loss : Percentage of packet loss (<1-100>)
|
||||
|
||||
### Example configuration file
|
||||
|
||||
[nodes]
|
||||
a: _ cpu=0.3
|
||||
b: app="sampleApp1; ./sampleApp2.sh" cpu=0.3
|
||||
[links]
|
||||
a:b delay=10ms bw=100
|
||||
|
||||
Note that `sampleApp1` and `sampleApp2` must be either installed in the system (ex: /usr/bin)
|
||||
or an absolute path needs to be given.
|
||||

||||

Experiments
|
||||
===========
|
||||
|
||||
Mini-NDN includes an experimentation framework which allows a user to create and automate
|
||||
networking experiments. Users can run existing experiments, included with Mini-NDN, or define
|
||||
their own custom experiment.
|
||||
|
||||
## Running existing experiments
|
||||
|
||||
Mini-NDN includes three example experiments that can be used to test the network or as reference
|
||||
for custom experiment implementations. `ndn-tools` must be installed to run the example
|
||||
experiments as each experiment uses both `ndnpingserver` and `ndnping`. Please see
|
||||
[INSTALL.md](../INSTALL.md) for instructions on installing `ndn-tools`.
|
||||
|
||||
To see a list of the available experiments, run Mini-NDN using the `--list-experiments` parameter:
|
||||
|
||||
minindn --list-experiments
|
||||
|
||||
To run an experiment, provide the experiment name as an argument to the `--experiment` parameter:
|
||||
|
||||
sudo minindn --experiment=pingall
|
||||
|
||||
Each experiment will run until completion or exit if there is an error setting up the
|
||||
test environment.
|
||||
|
||||
The three included experiments are set up using the same starting
|
||||
configuration. Each node runs NFD, NLSR, and an ndnpingserver which advertises the node's
|
||||
site name. After a waiting period to allow the network to converge (default is 60 seconds),
|
||||
the convergence status of the network is checked. If each node's FIB does not have an entry
|
||||
for every other node's router name and advertised prefix, the experiment is aborted and an error
|
||||
is reported.
|
||||
|
||||
#### Common experiment parameters
|
||||
|
||||
The time allowed for convergence (in seconds) can be configured using the `--ctime` parameter:
|
||||
|
||||
sudo minindn --ctime=30 ...
|
||||
|
||||
After the experiment has finished running, the command-line interface (CLI) will be launched and the
|
||||
user can then interact with the test environment. To disable the CLI and instead exit Mini-NDN
|
||||
as soon as the experiment has finished, use the `--no-cli` parameter:
|
||||
|
||||
sudo minindn --no-cli ...
|
||||
|
||||
To ping only a percentage of nodes `--pct-traffic` can be set.
|
||||
|
||||
sudo minindn --pct-traffic=0.5 ...
|
||||
|
||||
The above command will ping only 50% of other nodes from each node.
|
||||
The default value is 1 i.e. ping every other node.
|
||||
|
||||
To move the experiment results to a results directory from the working directory
|
||||
after the experiment is complete (either --no-cli or quit) the following option
|
||||
can be used:
|
||||
|
||||
sudo minindn --result-dir /home/mydir/result-dir ...
|
||||
|
||||
The included experiments are described in detail below along with additional
|
||||
parameters that can be provided to modify the execution of the experiments.
|
||||
|
||||
### Pingall experiment
|
||||
|
||||
**Scenario**: Each node in the network simultaneously pings every other node in the network at a
|
||||
one second interval.
|
||||
|
||||
**Experiment ID**: `--pingall`
|
||||
|
||||
The number of pings sent in the experiment can be configured using the `--nPings` parameter:
|
||||
|
||||
sudo minindn --experiment=pingall --nPings=120
|
||||
|
||||
By default, `--nPings` is 300 for the Pingall experiment.
|
||||
|
||||
### Failure experiment
|
||||
|
||||
**Scenario**: Each node in the network simultaneously pings every other node in the network at a
|
||||
one second interval. After 60 seconds, the node with the name "csu" is brought down. The node is
|
||||
left in a failed state for 120 seconds while the other nodes continue pinging. After this period,
|
||||
the failed node is recovered and pings are collected for an additional 90 seconds.
|
||||
|
||||
**Experiment ID**: `--failure`
|
||||
|
||||
`--nPings` is 300 for the Failure experiment and cannot be modified.
|
||||
|
||||
### Multiple failure experiment
|
||||
|
||||
**Scenario**: Each node in the network simultaneously pings every other node in the network at a
|
||||
one second interval. After 60 seconds, the first node in the network will be brought down and remain
|
||||
in failed state for 60 seconds. After the failure period, the node is recovered and the network
|
||||
is allowed to recover for 60 seconds. After the recovery period, the next node will go through this
|
||||
failure and recovery process. Once every node in the network has gone through the failure and
|
||||
recovery process, the experiment will end.
|
||||
|
||||
**Experiment ID**: `--multiple-failure`
|
||||
|
||||
`--nPings` is dependent on the size of the topology being tested. 120 pings are scheduled for
|
||||
each node's failure/recovery period as well as an additional 60 pings for the initial collection
|
||||
period.
|
||||
|
||||
### MCN failure experiment
|
||||
|
||||
**Scenario**: This is exactly like the failure experiment but instead of failing the node named "csu" it fails the most connected node (MCN) i.e the node with the most links.
|
||||
|
||||
Experiment ID: `--mcn-failure`
|
||||
|
||||
### Experiment data
|
||||
|
||||
The ping data is stored at `/tmp/minindn/node-name/ping-data`.
|
||||
|
||||
The ping server log is stored at `/tmp/minindn/node-name/ping-server`
|
||||
|
||||
## Creating custom experiments
|
||||
|
||||
Mini-NDN provides a simple Python based framework which allows a user to define their own experiment
|
||||
and run it from the command line.
|
||||
|
||||
To create an experiment, follow these steps:
|
||||
|
||||
1. Create a Python source file for the experiment in the `ndn/experiments` directory.
|
||||
|
||||
e.g.) `ndn/experiments/example.py`
|
||||
|
||||
2. Derive the experiment from the `Experiment` base class defined in
|
||||
`ndn/experiments/experiment.py`.
|
||||
|
||||
#!/usr/bin/python
|
||||
|
||||
from ndn.experiments.experiment import Experiment
|
||||
|
||||
class ExampleExperiment(Experiment):
|
||||
def __init__(self, args):
|
||||
Experiment.__init__(self, args)
|
||||
|
||||
3. Override `start()` if the experiments want to override NLSR setup and skip `setup()` and `run()`
|
||||
as described below. `start()` is the entry point for an experiment.
|
||||
|
||||
4. Override the `setup()` method to define how the experiment should be initialized
|
||||
|
||||
e.g.) Run an ndnping server in the background on each node
|
||||
|
||||
def setup(self):
|
||||
for host in self.net.hosts:
|
||||
host.cmd("ndnpingserver host.name &")
|
||||
|
||||
|
||||
5. Override the `run()` method to define how the experiment should behave
|
||||
|
||||
e.g.) Obtain the NFD status of each node and save it to file
|
||||
|
||||
def run(self):
|
||||
for host in self.net.hosts:
|
||||
host.cmd("nfdc status report > status.txt")
|
||||
|
||||
6. Register the experiment with the `ExperimentManager` to make the experiment runnable from the
|
||||
command line.
|
||||
|
||||
Experiment.register("example-name", ExampleExperiment)
|
||||
|
||||
The experiment can then be run from the command-line using the name registered.
|
||||
"example-name" in the above example:
|
||||
|
||||
sudo minindn --experiment=example-name
|
||||
|
||||

## Passing arguments to experiments
|
||||
|
||||
Mini-NDN has the capacity to pass arguments to experiments, insofar
|
||||
as they do not clash with those of Mini-NDN. This feature
|
||||
allows users to pass arguments to Mini-NDN and process them in an
|
||||
experiment without having to rewrite Mini-NDN's core.
|
||||
|
||||
An example of an experiment implementing this functionality is given in
|
||||
`ndn/experiments/arguments_experiment.py`, which demonstrates how to
|
||||
write code which handles arguments. Documentation for these arguments
|
||||
appears when called with `sudo minindn -h`, as does documentation for
|
||||
fixed arguments defined in core code, so it is strongly recommended to
|
||||
differentiate those you write yourself. Note that Bash and Zsh users
|
||||
can make use of autocomplete functionality when calling these arguments.
|
||||
|
||||
To run the experiment:
|
||||
|
||||
sudo minindn --experiment arg-exp --ds 226 --logging
|
||||
|
||||
The experiment will print out the supplied value for --ds and a boolean
|
||||
value for the presence of --logging. --experiment is a fixed argument of
|
||||
Mini-NDN.

Getting Started
|
||||
===============
|
||||
|
||||
## Installation
|
||||
Please see [INSTALL.md](../INSTALL.md) for instructions on installing Mini-NDN and its dependencies.
|
||||
|
||||
## Running Mini-NDN
|
||||
|
||||
To run Mini-NDN with the default topology, `ndn_utils/topologies/default-topology.conf`, type:
|
||||
|
||||
sudo minindn
|
||||
|
||||
A full list of options can be printed by using:
|
||||
|
||||
sudo minindn --help
|
||||
|
||||
To run Mini-NDN with a topology file, provide the filename as the first argument:
|
||||
|
||||
sudo minindn my-topology.conf
|
||||
|
||||
During set up, the list of nodes in the network will be listed as they are initialized:
|
||||
|
||||
*** Adding hosts:
|
||||
a b c d
|
||||
|
||||
After set up, the command-line interface (CLI) will display a prompt.
|
||||
|
||||
mini-ndn>
|
||||
|
||||
To interact with a node, first type the node's name and then the command to be executed:
|
||||
|
||||
mini-ndn> a echo "Hello, world!"
|
||||
Hello, world!
|
||||
|
||||
To see the status of the forwarder on the node:
|
||||
|
||||
mini-ndn> a nfdc status report
|
||||
|
||||
To see the status of routing on the node:
|
||||
|
||||
mini-ndn> a nlsrc status
|
||||
|
||||
To exit Mini-NDN, type `quit` in the CLI:
|
||||
|
||||
mini-ndn> quit
|
||||
|
||||
Another option to quit Mini-NDN is sending a SIGQUIT (ctrl+\). SIGINT (ctrl+c)
|
||||
is reserved for the purpose of stopping applications initiated on the minindn command
|
||||
line.
|
||||
|
||||
For a more in depth explanation of the CLI, please see the
|
||||
[Mininet Walkthrough](http://mininet.org/walkthrough/).
|
||||
|
||||
## Command-line options
|
||||
|
||||
To run Mini-NDN with a replica of the NDN testbed, use the `--testbed` parameter:
|
||||
|
||||
sudo minindn --testbed
|
||||
|
||||
To change the working directory from default `/tmp/minindn` following option can be used:
|
||||
|
||||
sudo minindn --work-dir /home/mydir/test
|
||||
|
||||
Autocomplete of command-line options is available for users of Bash and Zsh.
|
||||
|
||||
#### Routing options
|
||||
|
||||
To run minindn without NLSR, use the `--no-nlsr` parameter:
|
||||
|
||||
sudo minindn --no-nlsr
|
||||
|
||||
To run NLSR with hyperbolic routing enabled, use the `--routing` parameter:
|
||||
|
||||
sudo minindn --routing hr
|
||||
|
||||
Topology files given under ndn_utils/topologies/minindn* have hyperbolic coordinates configured
|
||||
and can be used with this option.
|
||||
|
||||
To run NLSR in dry-run mode, use the `--routing` parameter:
|
||||
|
||||
sudo minindn --routing dry
|
||||
|
||||
To configure the max number of faces added by NLSR to reach each name prefix, use the `--faces`
|
||||
parameter:
|
||||
|
||||
sudo minindn --faces 3
|
||||
|
||||
`--faces` can be an integer from 0 to 60; 0 indicates NLSR can add all available faces.
|
||||
|
||||
To run Mini-NDN with NLSR security configured
|
||||
|
||||
sudo minindn --nlsr-security
|
||||
|
||||
## Working Directory Structure
|
||||
|
||||
Currently Mini-NDN uses /tmp/minindn as the working directory if not specified otherwise by using
|
||||
the option --work-dir.
|
||||
|
||||
Each node is given a HOME directory under /tmp/minindn/node-name
|
||||
where node-name is the name of the node specified in the [nodes] section of the conf file.
|
||||
|
||||
### NFD
|
||||
NFD conf file is stored at `/tmp/minindn/node-name/node-name.conf`
|
||||
|
||||
NFD log file is stored at `/tmp/minindn/node-name/node-name.log`
|
||||
|
||||
`.ndn` folder is stored at `/tmp/minindn/node-name/.ndn`
|
||||
|
||||
### NLSR
|
||||
NLSR conf file is stored at `/tmp/minindn/node-name/nlsr.conf`
|
||||
|
||||
NLSR log file is stored at `/tmp/minindn/node-name/log/nlsr.log`
|
||||
|
||||
When security is enabled, NLSR security certificates are stored in: `/tmp/minindn/node-name/security`
|
||||
Note that no NLSR publishes the root certificate, Mini-NDN installs root.cert in security folder for each NLSR.

Mini-NDN Edit
|
||||
=============
|
||||
|
||||
Mini-NDN Edit is a GUI program designed to simplify the creation of Mini-NDN topology
|
||||
configuration files. Mini-NDN Edit allows the user to build a topology, configure the hosts and
|
||||
links, and generate a topology file that can be used by Mini-NDN.
|
||||
|
||||
|
||||
|
||||
## Working with topology files
|
||||
|
||||
#### File formats
|
||||
|
||||
There are two file formats used by Mini-NDN edit.
|
||||
|
||||
* `.mnndn` files store topology information used by the GUI. Mini-NDN Edit can open and
|
||||
save `.mnndn` files.
|
||||
|
||||
* `.conf` files are used by Mini-NDN to create and run topologies. Mini-NDN Edit can generate a
|
||||
`.conf` file from a `.mnndn` file. Mini-NDN edit cannot open `.conf` files. Please see
|
||||
[CONFIG-FILE.md](CONFIG.md) for more information on the content and format of `.conf` files.
|
||||
|
||||
#### File menu
|
||||
|
||||
|
||||
|
||||
* **New** - Erase the current canvas and provide a new empty topology
|
||||
* **Open** - Open a `.mnndn` topology file
|
||||
* **Save** - Save the current topology as a `.mnndn` topology file
|
||||
* **Generate** - Convert the current topology to a `.conf` file runnable by Mini-NDN
|
||||
* **Run** - Run the current topology in Mini-NDN. The GUI will disappear and Mini-NDN will run on
|
||||
the command-line.
|
||||
* **Quit** - Exit Mini-NDN edit
|
||||
|
||||
## Tools
|
||||
|
||||
### Cursor tool
|
||||
|
||||
|
||||
The *cursor tool* is used to select and move nodes in the topology. A selected node or link can be
|
||||
removed from the topology using the `backspace` key or by selecting `edit/cut`.
|
||||
|
||||
### Host tool
|
||||
|
||||
|
||||
The *host tool* is used to add a host node to the topology. Click on the canvas to create a new host
|
||||
node at the mouse cursor's position.
|
||||
|
||||
### Switch tool
|
||||
|
||||
|
||||
The *switch tool* is used to add a switch to the topology. Click on the canvas to create a new
|
||||
switch at the mouse cursor's position.
|
||||
|
||||
### Link tool
|
||||
|
||||
|
||||
The *link tool* is used to connect two nodes with a network link. Click on a node and drag the mouse
|
||||
cursor to another node to create a link between the two nodes.
|
||||
|
||||
## Configuration
|
||||
|
||||
#### Editing host information
|
||||
|
||||
To edit a host's information and configuration, right-click on the desired node and select
|
||||
`Host Options`.
|
||||
|
||||
The *Host Options* window will include tabs to modify the node's properties as well as the
|
||||
configuration files for NFD and NLSR on that node.
|
||||
|
||||
*Note: Network, Site, and Router in the NLSR tab are unused in v0.1.0*
|
||||
|
||||
|
||||
|
||||
#### Editing link configuration
|
||||
|
||||
To edit a link's configuration, right-click on the desired link and select `Link Options`.
|
||||
|
||||
The *Link Options* window will allow configuration of the link's bandwidth, delay, and loss rate.

Experiment
|
||||
==========
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
Mini-NDN uses a configuration file describing the topology and its parameters to setup a network.
|
||||
|
||||
The [nodes] section:
|
||||
|
||||
At the bare minimum, the node section describes the nodes present in the
|
||||
topology.
|
||||
|
||||
::
|
||||
|
||||
[nodes]
|
||||
a: key1=value1 key2=value2
|
||||
b: key1=value1
|
||||
|
||||
Any key and value passed here is accessible in Mini-NDN as:
|
||||
|
||||
::
|
||||
|
||||
ndn = Minindn(...)
|
||||
value = ndn.net.hosts[0].params['params'].get('key1', "defaultValue")
|
||||
|
||||
One can specify log levels for each node's NFD and NLSR using this key-value system:
|
||||
|
||||
::
|
||||
|
||||
[nodes]
|
||||
a: nfd-log-level=DEBUG nlsr-log-level=DEBUG
|
||||
b: nfd-log-level=INFO
|
||||
|
||||
To specify a log level for certain modules of NFD, the following line can be added to `nfd.py`:
|
||||
|
||||
::
|
||||
|
||||
node.cmd('infoedit -f {} -s log.Forwarder -v {}'.format(self.confFile, 'INFO'))
|
||||
|
||||
This will turn on FORWARDER logging to INFO for all nodes.
|
||||
|
||||
.. Todo: Add switch section
|
||||
|
||||
The [links] section:
|
||||
|
||||
The links section describes the links in the topology.
|
||||
|
||||
::
|
||||
|
||||
e.g.)
|
||||
|
||||
[links]
|
||||
a:b delay=10ms
|
||||
|
||||
This would create a link between a and b. 'b:a' would also result in the
|
||||
same. The following parameters can be configured for a node:
|
||||
|
||||
- delay : Delay parameter is a required parameter which defines the
|
||||
delay of the link (1-1000ms)
|
||||
|
||||
- bw : Bandwidth of a link (<1-1000> Mbps)
|
||||

Sample experiment may written as follows:
|
||||
|
||||
.. code:: python
|
||||
|
||||
from mininet.log import setLogLevel, info
|
||||
|

||||
|
||||
if __name__ == '__main__':
|
||||
setLogLevel('info')
|
||||
|
||||
Minindn.cleanUp()
|
||||
Minindn.verifyDependencies()
|
||||
|
||||
# Can pass a custom parser, custom topology, or any Mininet params here
|
||||
ndn = Minindn()
|
||||
|
||||

||||
# IPRoutingHelper.calcAllRoutes(ndn.net)
|
||||
# info("IP routes configured, start ping\n")
|
||||
# ndn.net.pingAll()
|
||||
|
||||
# Start apps with AppManager which registers a clean up function with ndn
|
||||
info('Starting NFD on nodes\n')
|
||||
nfds = AppManager(ndn, ndn.net.hosts, Nfd)
|
||||
info('Starting NLSR on nodes\n')
|
||||
nlsrs = AppManager(ndn, ndn.net.hosts, Nlsr)
|
||||
|
||||
# or can not start NLSRs with some delay in between:
|
||||
# nlsrs = AppManager(ndn, ndn.net.hosts, Nlsr)
|
||||
# for host in ndn.net.hosts:
|
||||
# nlsrs.startOnNode(host)
|
||||
# time.sleep(30)
|
||||
|
||||

|
||||
|
||||
# Calls the clean up functions registered via AppManager
|

ndn.stop()
|
||||
|
||||
Users may look at how the NFD and NLSR applications are written as a sub class of Application
|
||||
in the ``minindn/apps`` folder. Or users may choose to directly run their application on nodes
|
||||
such as ndnpingserver is run in ``minindn/helpers/experiment.py``.
|
||||
|
||||
Execution
|
||||
---------
|
||||
|
||||
To run Mini-NDN with the default topology,
|
||||
``ndn_utils/topologies/default-topology.conf``, type:
|
||||
|
||||
::
|
||||
|
||||
sudo python examples/minindn.py
|
||||
|
||||
To run Mini-NDN with a topology file, provide the filename as the first
|
||||
argument:
|
||||
|
||||
::
|
||||
|
||||
sudo python examples/minindn.py my-topology.conf
|
||||
|
||||
After Mini-NDN is installed, users can run examples from anywhere with python directly as follows:
|
||||
|
||||
::
|
||||
|
||||
sudo python /path/to/myexample.py
|
||||
|
||||
The user no longer needs to create an experiment in the old Mini-NDN way, then install it to the system before executing it via the minindn binary. The new examples can be separate from the Mini-NDN folder if the core is not being modified.
|
||||
|
||||
CLI Interface
|
||||
_____________
|
||||
|
||||
During set up, the list of nodes in the network will be listed as they
|
||||
are initialized:
|
||||
|
||||
::
|
||||
|
||||
*** Adding hosts:
|
||||
a b c d
|
||||
|
||||
After set up, the command-line interface (CLI) will display a prompt.
|
||||
|
||||
::
|
||||
|
||||
mini-ndn>
|
||||
|
||||
To interact with a node, first type the node's name and then the command
|
||||
to be executed:
|
||||
|
||||
::
|
||||
|
||||
mini-ndn> a echo "Hello, world!"
|
||||
Hello, world!
|
||||
|
||||
To see the status of the forwarder on the node:
|
||||
|
||||
::
|
||||
|
||||
mini-ndn> a nfdc status report
|
||||
|
||||
To see the status of routing on the node:
|
||||
|
||||
::
|
||||
|
||||
mini-ndn> a nlsrc status
|
||||
|
||||
To exit Mini-NDN, type ``quit`` in the CLI or use ``ctrl + D``:
|
||||
|
||||
::
|
||||
|
||||
mini-ndn> quit
|
||||
|
||||
``Ctrl + C`` is used to quit an application run in the foreground of the command line.
|
||||
|
||||
For a more in depth explanation of the CLI, please see the `Mininet
|
||||
Walkthrough <http://mininet.org/walkthrough/>`__.
|
||||
|
||||
To run NDN commands from the outside the command line user can also open a new terminal
|
||||
and export the HOME folder of a node ``export HOME=/tmp/minindn/a && cd ~``
|
||||
|
||||
Working Directory Structure
|
||||
---------------------------
|
||||
|
||||
Currently Mini-NDN uses /tmp/minindn as the working directory if not
|
||||
specified otherwise by using the option --work-dir.
|
||||
|
||||
Each node is given a HOME directory under /tmp/minindn/<node-name> where
|
||||
<node-name> is the name of the node specified in the [nodes] section of
|
||||
the conf file.
|
||||
|
||||
NFD
|
||||
___
|
||||
|
||||
- NFD conf file is stored at ``/tmp/minindn/<node-name>/nfd.conf``
|
||||
|
||||
- NFD log file is stored at ``/tmp/minindn/<node-name>/log/nfd.log``
|
||||
|
||||
- ``.ndn`` folder is stored at ``/tmp/minindn/<node-name>/.ndn``
|
||||
|
||||
NLSR
|
||||
____
|
||||
|
||||
- NLSR conf file is stored at ``/tmp/minindn/<node-name>/nlsr.conf``
|
||||
- NLSR log file is stored at ``/tmp/minindn/<node-name>/log/nlsr.log``
|
||||
|
||||
When security is enabled, NLSR security certificates are stored in:
|
||||
``/tmp/minindn/<node-name>/security`` Note that no NLSR publishes the root
|
||||
certificate, Mini-NDN installs root.cert in security folder for each
|
||||
NLSR.

FAQ
|
||||
=========
|
||||
|
||||
* ``How does Mini-NDN work?``
|
||||
|
||||
Mini-NDN's principles of operation most heavily rely on the underlying Mininet code it relies on.
|
||||
Mininet uses a combination of limited containerization via network namespaces (which give processes
|
||||
isolated interfaces and routing tables) and emulated ethernet connections via veth connections.
|
||||
In practical terms, Mini-NDN ensures that processes running on distinct nodes will run seperately
|
||||
and without interfering with each other.
|
||||
|
||||
* ``How does Mini-NDN apply link loss/delay/etc.?``
|
||||
|
||||
Mini-NDN relies on Mininet's code, which in turn uses the Linux tc utility on a stations' virtualized
|
||||
interfaces to apply configurations known as qdiscs to these links. Note that these will only be applied
|
||||
on egress packets from a station where it's applied.
|
||||
For more information on qdiscs and tc, view the information `here <http://wiki.linuxwall.info/doku.php/en%3aressources%3adossiers%3anetworking%3atraffic_control>`_.
|
||||
|
||||
* ``Why use Mini-NDN rather than a simulator such as ndnSIM?``
|
||||
|
||||
Mini-NDN is easier and faster to use because, rather than serving as a mathematical model of a network,
|
||||
it is instead running real NDN code on a real Linux kernel. This also means it's quite useful for testing code changes, as it can more accurately test the interaction of software componenents.

||||
For this simple example, we use the default topology:
|
||||
For this simple example, we can use a single node topology with node 'a'
|
||||
|
||||
c----a----b----d
|
||||
If we want node 'a' to connect to the host machine, we need to add a
|
||||
"root" node which has a link with node "a."
|
||||
|
||||
If we want node "a" to connect to the host machine, we need to add a "root" node which has a link with node "a."
|
||||
Then the following code can be used:
|
||||
|
||||
To do so, we need to add the following import statement at the top of `bin/minindn`:
|
||||
.. code:: python
|
||||
|
||||
```python
|
||||
from mininet.node import Node
|
||||
```
|
||||
topo = Topo()
|
||||
root = topo.addHost('root', inNamespace=False)
|
||||
a = topo.addHost('a')
|
||||
topo.addLink(root, a, delay='10ms')
|
||||
|
||||
Then the following lines can be added to `bin/minindn` before net.start():
|
||||
ndn = Minindn(topo=topo)
|
||||
|
||||
```python
|
||||
root = Node( 'root', inNamespace=False )
|
||||
net.addLink(root, 'a')
|
||||
```
|
||||
...
|
||||
|
||||
Adding these before net.start() is important as node "root" would then be assigned an IP automatically.

Install
|

=======
|
||||
|
||||
Prerequisites
|
||||
-------------
|
||||
|
||||
For this guide, you will need a laptop/desktop with a recent version of
|
||||
a Linux distro that is supported by Mininet. For this guide, the *Ubuntu 18.04 LTS* release was used.
|
||||
Some tweaks maybe required to Mini-NDN's install.sh file for other distros.
|
||||
Note that you'll need administrative privileges in order to download and install
|
||||
extra packages and also to execute **Mini-NDN**.
|
||||
|
||||
Using Vagrantfile
|
||||
-----------------
|
||||
|
||||
With Vagrant installed, simply do ``vagrant up`` which will bring up an Ubuntu 18.04 virtual machine
|
||||
and install Mini-NDN and all its dependencies on it. Please make sure to tweak the CPU core count
|
||||
(default 4 cores) and RAM (default 4GB) according to your needs before doing vagrant up. Mini-NDN
|
||||
can be found in /home/vagrant/mini-ndn which is a symlink to /vagrant if Vagrantfile was used from within mini-ndn cloned on the host. Otherwise it is an actual clone of mini-ndn.
|
||||
|
||||
Using install.sh
|
||||
----------------
|
||||
|
||||
Mini-NDN depends on Mininet and NDN software to be installed in the system.
|
||||
If you have all the dependencies (see sections below) **installed in the system** simply
|
||||
clone this repository and run:
|
||||
|
||||
::
|
||||
|
||||
./install.sh -i
|
||||
|
||||
The ``-i`` option uses ``setup.py develop`` to point the system install
|
||||
to the current directory. So any changes made to the cloned ``mini-ndn``
|
||||
folder will be used without having to install it again to the system.
|
||||
If you do not need to modify the core of Mini-NDN, then setup.py install (or pip install .)
|
||||
can be used directly. See :doc:`experiment <experiment>` for more information on running.
|
||||
|
||||
If you don't have the dependencies, the following command will
|
||||
install them from source along with Mini-NDN. The dependencies include
|
||||
Mininet, NDN core (ndn-cxx, NFD, Chronosync, PSync, NLSR), Infoedit,
|
||||
and NDN Common Client Libraries (CCL). If you do not wish to install
|
||||
the master versions of the NDN core or want to switch to specific versions,
|
||||
you can edit the install.sh with release tags/specific versions.
|
||||
|
||||
.. _scaling-note:
|
||||
.. important::
|
||||
If you wish to scale Mini-NDN experiments and do not have use for security extensions
|
||||
in your emulations, you should apply the ndn-cxx patch given in the ``patches`` folder
|
||||
using ``./install.sh -p`` before running the following commands. The ndn-cxx patch is
|
||||
taken from ndnSIM which provides an in-memory dummy KeyChain to reduce CPU computations.
|
||||
After these patches are applied sleep time after NFD, nfdc, NLSR, etc. is not required
|
||||
making the startup **MUCH** faster and scaling of Mini-NDN **MUCH** better.
|
||||
|
||||
::
|
||||
|
||||
./install.sh -a
|
||||
|
||||
This pulls the NDN software from Github to ``ndn-src`` folder under the project.
|
||||
|
||||
.. note::
|
||||
If any changes are made to ``ndn-src`` folder, please don't forgot to re-install
|
||||
the sources to the system.
|
||||
|
||||
To install without CCL, use:
|
||||
|
||||
::
|
||||
|
||||
./install.sh -mni
|
||||
|
||||
See ``install.sh -h`` for detailed options.
|
||||
|
||||
Installing Dependencies
|
||||
-----------------------
|
||||
|
||||
Mininet
|
||||
_______
|
||||
|
||||
Mini-NDN is based on Mininet. To install Mininet:
|
||||
|
||||
::
|
||||
|
||||
git clone --depth 1 https://github.com/mininet/mininet.git
|
||||
|
||||
After Mininet source is on your system, run the following command to
|
||||
install Mininet core dependencies and Open vSwitch:
|
||||
|
||||
::
|
||||
|
||||
./util/install.sh -nv
|
||||
|
||||
To check if Mininet is working correctly, run this test:
|
||||
|
||||
::
|
||||
|
||||
sudo mn --test pingall
|
||||
|
||||
This will print out a series of statements that show the test setup and
|
||||
the results of the test. Look for ``Results:`` two-thirds of the way
|
||||
down where it will indicate the percentage of dropped packets. Your
|
||||
results should show "0% dropped (2/2 received)".
|
||||
|
||||
NOTE: Mini-NDN, while providing a high level of emulation of hosts,
|
||||
requires programs to be installed onto your computer. It will not work
|
||||
if they are not installed. If you do not want NDN software installed
|
||||
onto your computer, you can use a virtual machine, which can be quite
|
||||
simply set up with the provided Vagrantfile.
|
||||
|
||||
NDN dependencies
|
||||
________________
|
||||
|
||||
Each node in Mini-NDN will run the official implementation of NDN
|
||||
installed on your system. The following dependencies are needed:
|
||||
|
||||
Mini-NDN uses NFD, NLSR, and ndn-tools.
|
||||
|
||||
- To install NFD: https://named-data.net/doc/NFD/current/INSTALL.html
|
||||
- To install NLSR: https://named-data.net/doc/NLSR/current/INSTALL.html
|
||||
- To install ndn-tools: https://github.com/named-data/ndn-tools
|
||||
|
||||
.. warning::
|
||||
Please do not try to install NDN software from both the source (GitHub) and PPA (apt).
|
||||
It will not work in most cases! If you used ./install.sh -a in the past but now want
|
||||
to use apt, please run ``sudo ./waf uninstall`` in all the NDN projects before proceeding
|
||||
with apt. Similarly, remove from apt if switching to source.
|
||||
|
||||
Please see the :ref:`scaling-note <scaling-note>` to learn about disabling
|
||||
security for better scalability.
|
||||
|
||||
Note that all three of these can be installed from the Named Data PPA.
|
||||
Instructions for setting it up can be found in the NFD installation
|
||||
instructions. Note that PPA and installs from source **cannot** be
|
||||
mixed. You must completely remove PPA installs from the system if switching
|
||||
to source and vice-versa.
|
||||
|
||||
For PPA installs, if you are using a custom nfd.conf file in an experiment, you should
|
||||
place it in /usr/local/etc/ndn/ rather than /etc/ndn/. This is to avoid
|
||||
a bug from the default configuration file for the PPA, which is
|
||||
incompatible with Mini-NDN.
|
||||
|
||||
Infoedit
|
||||
________
|
||||
|
||||
Infoedit is used to edit configuration files for NFD and NLSR.
|
||||
To install infoedit:
|
||||
|
||||
::
|
||||
|
||||
git clone --depth 1 https://github.com/NDN-Routing/infoedit
|
||||
cd infoedit
|
||||
make
|
||||
sudo make install
|
||||
|
||||
Verification
|
||||
------------
|
||||
|
||||
You can execute the following example to bring up the Mini-NDN command line
|
||||
with NFD and NLSR running on each node:
|
||||
|
||||
::
|
||||
|
||||
sudo python examples/mnndn.py
|
||||
|
||||
You can use these steps to run the sample pingall experiment:
|
||||
|
||||
1. Issue the command: ``sudo python examples/nlsr/pingall.py``
|
||||
2. When the ``mini-ndn>`` CLI prompt appears, the experiment has
|
||||
finished. On the Mini-NDN CLI, issue the command ``exit`` to exit the
|
||||
experiment.
|
||||
3. Issue the command:
|
||||
``grep -c content /tmp/minindn/*/ping-data/*.txt``. Each file should
|
||||
report a count of 50.
|
||||
4. Issue the command:
|
||||
``grep -c timeout /tmp/minindn/*/ping-data/*.txt``. Each file should
|
||||
report a count of 0.

Introduction
|
||||
=================
|
||||
|
||||
If you are new to the NDN community of software generally, read the
|
||||
`Contributor's Guide <https://github.com/named-data/NFD/blob/master/CONTRIBUTING.md>`_.
|
||||
|
||||
What is Mini-NDN?
|
||||
-----------------
|
||||
|
||||
Mini-NDN is a lightweight networking emulation tool that enables testing, experimentation, and
|
||||
research on the NDN platform. It was initially based on `Mini-CCNx <https://github.com/chesteve/mn-ccnx>`_ which was a fork of `Mininet <https://github.com/mininet/mininet>`_. Mini-NDN uses the NDN libraries, NFD, NLSR, and tools released by the `NDN project <http://named-data.net/codebase/platform/>`_ to emulate an NDN network on a single system.
|
||||
|
||||
The first release of Mini-NDN is developed by members of the NSF-sponsored NDN project team.
|
||||
Mini-NDN is open to contribution from the public.
