Abstract Abstract
Segment Routing (SR) leverages source routing. A node steers a Segment Routing (SR) leverages source routing. A node steers a
packet through a controlled set of instructions, called segments, by packet through a controlled set of instructions, called segments, by
prepending the packet with an SR header. A segment can represent any prepending the packet with an SR header. A segment can represent any
instruction, topological or service-based. SR allows to enforce a instruction, topological or service-based. SR allows to enforce a
flow through any topological path and service chain while maintaining flow through any topological path and service chain while maintaining
per-flow state only at the ingress node of the SR domain. per-flow state only at the ingress node of the SR domain.
