Abstract:
The Path Computation Element Communication Protocol (PCEP) provides
mechanisms for Path Computation Elements (PCEs) to perform path
computations in response to Path Computation Clients (PCCs) requests.
Segment Routing (SR) can be used to steer packets through a network
employing the source routing paradigm. Stateful PCEP extensions for
SR allow a PCE to maintain state and to control and initiate SR
Traffic Engineering (TE) paths.
PCEP supports grouping of two unidirectional MPLS-TE Label Switched
Paths (LSPs), signaled via RSVP-TE, using association. This document
defines PCEP extensions for grouping two unidirectional SR paths (one
in each direction in the network) into a single associated
bidirectional SR path. The mechanisms defined in this document are
applicable to both stateless and stateful PCEs for PCE-initiated and
PCC-initiated LSPs.
