# Rumba: A framework to install, bootstrap a RINA network
Rumba is part of ARCFIRE 2020, Work Package 3. It is a framework in
Python which allows user to write a Python script to define a RINA
network. The physical graph needed for this RINA network is then
calculated and realised on one of the supported testbeds. Next, one of
the supported RINA prototypes is installed. After installation, the
network is bootstrapped. For an example of such a Python script, have
a look at the examples/ folder.
## Workflow, both external and internal:
1. User defines the network graph, creating instances of model.Node
and model.DIF classes
2. User creates an instance of a Testbed class
3. User creates an instance of prototype.Experiment class, passing
the testbed instance and a list of Node instances
1. At the end of the base Experiment constructor, the
generate function is called to generate information about
per-node IPCPs, registrations and enrollment, ready to be
used by the plugins
4. User calls run() on the prototype.Experiment instance:
1. run() calls Testbed.swap_in(), passing the Experiment, and
filling in the missing information
2. run() calls a prototype-specific setup function, to create the
required IPCPs, perform registrations, enrollments, etc.
3. Perform tests (TODO)
4. run() calls Testbed.swap_out()
## Installation
Rumba can be found on the
[PyPi](https://pypi.python.org/pypi/Rumba) and can thus be
installed through pip, by using `pip install rumba`. However, to
install the latest version, after cloning the repository, a user
can also issue `python setup.py install`.
## Supported prototypes
* [IRATI](https://github.com/IRATI/stack) is an open source
implementation of the RINA architecture targeted at the OS/Linux
system, initially developed by the FP7-IRATI project.
* [rlite](https://github.com/vmaffione/rlite) is a lightweight Free
and Open Source implementation of the Recursive InterNetwork
Architecture (RINA) for GNU/Linux operating systems.
* Ouroboros is a user-space implementation of RINA with a focus on
portability. It is written in C89 and works on any POSIX.1-2008
enabled system.
## Supported testbeds
* [QEMU](http://wiki.qemu-project.org/Main_Page) is a generic and
open source machine emulator and virtualizer.
* [Emulab](https://www.emulab.net/) is a network testbed, giving
researchers a wide range of environments in which to develop,
debug, and evaluate their systems.
* [jFed](http://jfed.iminds.be/) is a Java-based framework for
testbed federation.
In order to use the jFed testbed, a user first needs to download
his/her key from
[https://authority.ilabt.iminds.be/](https://authority.ilabt.iminds.be/)
After logging in, click on *Download your certificate*. Save the
contents in a file (for example cert.pem). A jFed testbed instance
is defined as follows:
tb = jfed.Testbed(exp_name = "rochefort10",
username = "ricksanchez",
cert_file = "/home/morty/cert.pem")
Here the experiment name is rochefort10, the user's name is
ricksanchez, and the certificate can be found in
/home/morty/cert.pem. An absolute path must be used for cert_file.
Before running the rumba you must run an SSH agent in same terminal.
This will also avoid you having to enter the passphrase for every
login to a node by the framework if you are not on an IPv6 enabled network.
(Apart from asking for the passphrase to login to the nodes, the framework
will always ask for the passphrase since it is needed by the jFed
CLI as well.) In order to start an SSH agent and to add the
certificate, type the following commands:
$ eval `ssh-agent`
$ ssh-add /home/morty/cert.pem
To access a node once the experiment swapped in, use the following
command (in the same terminal where ssh-agent was run):
$ ssh -A -oProxyCommand="ssh -i $CERTPATH
-o StrictHostKeyChecking=no $USER@bastion.test.iminds.be
nc $NODENAME.$EXP.wall2-ilabt-iminds-be.wall2.ilabt.iminds.be 22"
$USER@$NODENAME.$EXP.wall2-ilabt-iminds-be.wall2.ilabt.iminds.be
where $CERTPATH is the absolute path of the certificate (e.g.
/home/morty/cert.pem), $USER is the jFed username (e.g. "ricksanchez"),
$NODENAME is the name of the node you want to access (e.g. "a"),
and $EXP is the name of the experiment (e.g. "rochefort10").
