Abstract:
Segment Routing (SR) leverages the source routing and tunneling
paradigms. A node steers a packet through a controlled set of
instructions, called segments, by prepending the packet with an SR
header. A segment can represent any instruction, topological or
service-based. A segment can have a local semantic to an SR node or
global within an SR domain. SR allows to enforce a flow through any
topological path and service chain while maintaining per-flow state
only at the ingress node to the SR domain.
The Segment Routing architecture can be directly applied to the MPLS
dataplane with no change on the forwarding plane. It requires minor
extension to the existing link-state routing protocols. Segment
Routing can also be applied to IPv6 with a new type of routing
extension header.
