Abstract:
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). A Segment Routed Path can
be derived from a variety of mechanisms, including an IGP Shortest
Path Tree (SPT), explicit configuration, or a Path Computation
Element (PCE). This document specifies extensions to the Path
Computation Element Protocol (PCEP) that allow a stateful PCE to
compute and instantiate Traffic Engineering paths, as well as a PCC
to request a path subject to certain constraint(s) and optimization
criteria in SR networks.
