Segment Routing (SR) leverages source routing. 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. SR allows for the
enforcement of a flow through any topological path while maintaining
per-flow state only at the ingress node of the SR domain.
The Segment Routing architecture can be directly applied to the MPLS
data plane with no change on the forwarding plane. It requires a
minor extension to the existing link-state routing protocols.
This document illustrates the application of Segment Routing to solve
the BGP Egress Peer Engineering (BGP-EPE) requirement. The SR-based
BGP-EPE solution allows a centralized (Software-Defined Networking,
or SDN) controller to program any egress peer policy at ingress
border routers or at hosts within the domain.
This document is a product of the Source Packet Routing in Networking Working Group of the IETF.
