Rumba is a Python framework that allows users to write Python scripts to define RINA networks and run scripted experiments. First, Rumba, creates a physical network on one of the selected testbed. If needed, Rumba can do an installation of the RINA prototype on the testbed machines. The RINA network is then bootstrapped on the available nodes. Finally, the experiment can be swapped out of the testbed.
