Title : PCC-PCE Communication Requirements for Point
to Multipoint Traffic Engineering
Author(s) : S. Yasukawa, A. Farrel
Filename : draft-yasukawa-pce-p2mp-req-00.txt

The Path Computation Element (PCE) provides functions of path
computation 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 traffic engineered point-to-multipoint (P2MP)
label switched paths (LSPs). Since P2MP 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 networks.
Generic requirements for a communication protocol between Path
Computation Clients (PCCs) and PCEs are presented in "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
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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
