Workflow
************************
1. Define the network graph, creating instances of model.Node and
model.DIF classes. Experiments can import rumba.model to obtain all
Rumba classes needed to run an experiment.
2. Create an instance of a specific model.Testbed class (QEMU, Docker,
Local, Emulab or jFed).
3. Create an instance of the selected prototype.Experiment class
(Ouroboros, rlite, IRATI), passing the testbed instance and a list
of Node instances.
* 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 prototype plugins.
4. Call methods on the prototype.Experiment instance:
* swap_in() swaps the experiment in on the testbed, and fills in
the missing information in the model.
* install_prototype() installs the chosen prototype on the testbed
(if necessary). Currently an Ubuntu image is assumed.
* bootstrap_prototype() calls a prototype-specific setup function,
to create the required IPCPs, perform registrations,
enrollments, etc.
* swap_out() swaps the experiment out of the testbed.
5. Optionally run a Storyboard to emulate real network traffic.
Accessing nodes after swap-in
-----------------------------
To access a node once the experiment is swapped in, use the following
command (in the same terminal where ssh-agent was run in case of jFed): ::
$ rumba-access $NODE_NAME
Where $NODE_NAME is the name of the node to access.
