Received changes through RFC Editor sync (created document RFC 9603, created became rfc relationship between draft-ietf-pce-segment-routing-ipv6 and RFC 9603, set abstract to 'Segment Routing (SR) can be used to steer packets through a network using the IPv6 or MPLS data plane, employing the source routing paradigm.

An SR 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 data planes, a PCE should be able to compute an SR Path for both MPLS and IPv6 data planes. The Path Computation Element Communication Protocol (PCEP) extension and mechanisms to support SR-MPLS have been defined. This document outlines the necessary extensions to support SR for the IPv6 data plane within PCEP.', set pages to 23, set standardization level to Proposed Standard, added RFC published event at 2024-07-29)
