The Path Computation Element (PCE) provides path computation
functions in support of traffic engineering in Multiprotocol Label
Switching (MPLS) and Generalized MPLS (GMPLS) networks.

Extensions to the MPLS and GMPLS signaling and routing protocols have
been made in support of point-to-multipoint (P2MP) Traffic Engineered
(TE) Label Switched Paths (LSPs).  The use of PCE in MPLS networks is
already established, and since P2MP TE LSP routes are sometimes
complex to compute, it is likely that PCE will be used for P2MP LSPs.

Generic requirements for a communication protocol between Path
Computation Clients (PCCs) and PCEs are presented in RFC 4657, "Path
Computation Element (PCE) Communication Protocol Generic
Requirements".  This document complements the generic requirements and
presents a detailed set of PCC-PCE communication protocol
requirements for point-to-multipoint MPLS/GMPLS traffic engineering.
