ARCFIRE researchers were present at the 3rd Fed4FIRE conference to give a demo of Rumba, the framework in Python developed in Work Package 3 of ARCFIRE which allows a user to write a Python script to define a RINA network. A 5,5 hour demonstration of RINA and Rumba was given in the poster and demo session of the conference.  There were 24 other demonstrations happening at the same time. Many people were interested in Rumba, and a lot of positive feedback was received, mainly on the fact that RINA (and Rumba) simplifies networking management tremendously.
