Huawei Technologies Nokia A Segment Routing (SR) Policy ([RFC9256]) is a non-empty set of SR Candidate Paths, that all share the same <headend, color, endpoint> tuple. This document extends [RFC8664] to fully support the SR Policy construct. SR Policy is modeled in PCEP as an Association of one or more SR Candidate Paths. PCEP extensions are defined to signal additional attributes of an SR Policy, which are not covered by [RFC8664]. The mechanism is applicable to all data planes of SR (MPLS, SRv6, etc.).
