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).

This document examines the applicability of PCE to path computation
for P2MP TE LSPs in MPLS and GMPLS networks.  It describes the
motivation for using a PCE to compute these paths and examines which
of the PCE architectural models are appropriate.  This memo provides 
information for the Internet community.

This document is a product of the Path Computation Element Working Group of the IETF.
