Abstract:
A Segment Routing (SR) Policy is an ordered list of instructions,
called "segments" that represent a source-routed policy. Packet
flows are steered into an SR Policy on a node where it is
instantiated, called a headend node. An SR Policy is made of one or
more candidate paths.
This document specifies the Path Computation Element Communication
Protocol (PCEP) extension to signal candidate paths of an SR Policy.
Additionally, this document updates RFC 8231 to allow delegation and
setup of an SR Label Switched Path (LSP), without using the path
computation request and reply messages. This document is applicable
to both Segment Routing over MPLS (SR-MPLS) and Segment Routing over
IPv6 (SRv6).
