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.
