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.
The Stateful PCE extensions allow stateful control of Multiprotocol
Label Switching (MPLS) Traffic Engineering (TE) Label Switched Paths
(LSPs) using PCEP.
This document defines PCEP extensions for grouping two unidirectional
MPLS TE LSPs (one in each direction in the network) into an
Associated Bidirectional LSP. The mechanisms defined in this
document can be applied using a Stateful PCE for both PCE-Initiated
and PCC-Initiated LSPs, as well as when using a Stateless PCE. The
procedures defined are applicable to the LSPs using Resource
Reservation Protocol - Traffic Engineering (RSVP-TE) for signaling.
