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). An SR path can be
derived from a variety of mechanisms, including an IGP Shortest Path
Tree (SPT), an 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
Path Computation Client (PCC) to request a path subject to certain
constraints and optimization criteria in SR networks.

This document updates RFC 8408.

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 standardization state and status of this protocol. Distribution of
this memo is unlimited.
