The IESG has approved the following document: - 'PCEP Extensions for Segment Routing' (draft-ietf-pce-segment-routing-16.txt) as Proposed Standard This document is the product of the Path Computation Element Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-pce-segment-routing/ Technical Summary 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). 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). 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 PCC to request a path subject to certain constraints and optimization criteria in SR networks. Working Group Summary No controversies. A 2nd WG LC was issued after the draft had a substantial change after the 1st call. The shepherd review also led to simplification of text. The authors handled all comments raised. The consensus behind the document is good. Document Quality There are several PCEP implementations supporting Segment Routing. This includes commercial as well as open source implementations. There was also a discussion related to backward compatibility as related to some implementations before RFC8408 was published. Substantial review was done by Adrian Farrel and Dhruv Dhody. Personnel Who is the Document Shepherd for this document? Dhruv Dhody Who is the Responsible Area Director? Deborah Brungard
