The Path Computation Element (PCE) provides path computation
functions in support of traffic engineering in Multi-Protocol 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). Since P2MP TE LSP routes are
sometimes complex to compute, and given the use of PCE in MPLS
networks it is likely that PCE will be used in P2MP MPLS-TE networks.

Generic requirements for a communication protocol between Path
Computation Clients (PCCs) and PCEs are presented in "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 traffic engineering.

NOTE:   The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
