Technical Summary

   Segment Routing (SR) can be used to steer packets through an IPv6 or
   MPLS network using the source routing paradigm.  SR enables any head-
   end node to select any path without relying on a hop-by-hop signaling
   technique (e.g., LDP or RSVP-TE).

   A Segment Routed Path can be derived from a variety of mechanisms,
   including an IGP Shortest Path Tree (SPT), explicit configuration, or
   a Path Computation Element(PCE).

   Since SR can be applied to both MPLS and IPv6 forwarding planes, a
   PCE should be able to compute an SR Path for both MPLS and IPv6
   forwarding planes.  The PCEP extension and mechanisms to support SR-
   MPLS have been defined.  This document describes the extensions
   required for SR support for the IPv6 data plane in the Path
   Computation Element communication Protocol (PCEP).

Working Group Summary

   From the shepherd writeup:

   “Concurrence of a few individuals, with others being silent.”

   The document appears to have received adequate review from the WG. 
   Although the spring WG was notified there weren’t any cross-WG 
   reviews received, however there is said to be sufficient 
   common participation in the WGs to mitigate concerns. 

Document Quality

   Implementations are reported in the document and also noted in the
   shepherd writeup. 

Personnel

   The Document Shepherd for this document is Hariharan Ananthakrishnan.
   The Responsible Area Director is John Scudder.
