Technical Summary

   Segment Routing (SR) leverages the source routing paradigm.  A node
   steers a packet through an ordered list of instructions, called
   segments.  A segment can represent any instruction, topological or
   service-based.  A segment can have a semantic local to an SR node or
   global within an SR domain.  SR allows to enforce a flow through any
   topological path while maintaining per-flow state only at the ingress
   nodes to the SR domain.

Working Group Summary

   This is the main document that is coming out of the WG -- support has 
    been strong throughout.

Document Quality

   Several commercial implementations and deployments of the SPRING architecture exist.
