Abstract:
Segment Routing (SR) leverages the source routing paradigm. 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. IGP-based segments
require 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.
