This document specifies the Path Computation Element (PCE)
Communication Protocol (PCEP) for communications between a Path
Computation Client (PCC) and a PCE, or between two PCEs.  Such
interactions include path computation requests and path computation
replies as well as notifications of specific states related to the
use of a PCE in the context of Multiprotocol Label Switching (MPLS)
and Generalized MPLS (GMPLS) Traffic Engineering.  PCEP is designed
to be flexible and extensible so as to easily allow for the addition
of further messages and objects, should further requirements be
expressed in the future.  [STANDARDS TRACK]
