Clarence Filsfils is a Distinguished Engineer at Cisco Systems where he holds key roles in Engineering and Marketing. Clarence has played a leadership role in the development of Quality of Service, IP/MPLS Routing Resiliency, Large-Scale Routing and IP/Optical Integrated Control-Plane technology at Cisco Systems. Clarence is a regular speaker at leading industry Conferences and Standards Development Organizations like the IETF. Clarence holds over 100 patents and has published several industry technology papers on Routing and Quality of Service. Clarence is also the author of a recent industry publication: “Service Provider deployments of Quality of Service (QoS). Clarence holds a Masters in Management from Solvay Business School and a Masters of Engineering in Computer Science from the University of Liege.
Abstract: In this talk, we introduce Segment Routing, a simple breakthrough in network engineering technology that may add benefit to IP and MPLS network operations. Segment Routing (SR) works by encoding a path across a network as an ordered list of segments, which may be links, multi-hop tunnels between nodes, and more. SR uses today's dataplane technologies without any modification, supports MPLS, IPv4 and IPv6, and requires only very modest changes to existing routing protocols. SR is also fully documented in IETF drafts with both multi-vendor and multi-operator contribution, thereby increasing the likelihood of interoperable implementations.

Segment Routing allows operators to program new service topologies without the traditional concerns around network state explosion. Using SDN procedures, the head end can program a ordered list of segment identifiers (MPLS labels, IPv6 routing headers) that enable explicit source routing. This can allow for service level differentiation, potentially providing new enhanced service offering opportunities for operators. SR can be introduced slowly into a network without any flag day events, thereby minimizing disruption.
