The Path Computation Element (PCE) provides path computation functionsin support of traffic engineering in Multiprotocol Label Switching(MPLS) and Generalized MPLS (GMPLS) networks. Extensions to the MPLSand GMPLS signaling and routing protocols have been made in support ofpoint-to-multipoint (P2MP) Traffic Engineered (TE) Label SwitchedPaths (LSPs). This document examines the applicability of PCE to pathcomputation for P2MP TE LSPs in MPLS and GMPLS networks. It describesthe motivation for using a PCE to compute these paths, and examineswhich of the PCE architectural models are appropriate.
