RINA is a Recursive InterNetwork Architecture that uses a single consistent layering model and API. ARCFIRE aims to demonstrate the benefits of RINA technology at large scale using the FIRE+ experimental infrastructure. Over 100 nodes and 10s-100s of DIFs will be used in a week long experiment examining DDoS attacks, multi-layer management, and heterogeneous access networks. Results will provide compelling cases for RINA deployment by converging operators, application developers, and end users.
