Path Computation Element Communication Protocol (PCEP) Extensions for Segment Routing
RFC 8664

Received changes through RFC Editor sync (created alias RFC 8664, changed title to 'Path Computation Element Communication Protocol (PCEP) Extensions for Segment Routing', changed abstract to 'Segment Routing (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). It depends only on "segments" that are advertised by link-state Interior Gateway Protocols (IGPs). An SR path can be derived from a variety of mechanisms, including an IGP Shortest Path Tree (SPT), an explicit configuration, or a Path Computation Element (PCE). This document specifies extensions to the Path Computation Element Communication Protocol (PCEP) that allow a stateful PCE to compute and initiate Traffic-Engineering (TE) paths, as well as a Path Computation Client (PCC) to request a path subject to certain constraints and optimization criteria in SR networks.

This document updates RFC 8408.', changed pages to 29, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2019-12-06, changed IESG state to RFC Published, created updates relation between draft-ietf-pce-segment-routing and RFC 8408)
