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. 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).
This document is a product of the Path Computation Element Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
