he RARE (Router for Academia, Research & Education) project (https://wiki.geant.org/display/RARE/) has been successful in the first two years of the GÉANT GN4-3 project in creating a new, performant and feature rich open routing platform. It combines the FreeRouter control plane and a P4/DPDK data plane. Running on a 32 x 100G Wedge with the Tofino forwarding chipset it can deliver Terabits/s of networking at line rate.
The coupling of RARE + FreeRouter gave birth to ROS (the RARE Operating System), which provides an impressive list of feature (see the complete feature list athttps://wiki.geant.org/display/RARE/) that supports various data centre architectures. ROS provides also all the management requirements (TACACS, configuration management, monitoring with Prometheus) allowing ROS to be production ready. The current hardware on which ROS runs was designed for data centre and used in FaceBook data centre.
