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.
Although PCEP explicitly makes no assumptions regarding the
information available to the PCE, it also makes no provisions for PCE
control of timing and sequence of path computations within and across
PCEP sessions. This document describes a set of extensions to PCEP
to enable stateful control of MPLS-TE and GMPLS LSPs via PCEP.
