Internet Engineering Task Force (IETF) Q. Zhao, Ed. Request for Comments: 6006 Huawei Technology Category: Standards Track D. King, Ed. ISSN: 2070-1721 Old Dog Consulting F. Verhaeghe Thales Communication France T. Takeda NTT Corporation Z. Ali Cisco Systems, Inc. J. Meuric France Telecom September 2010 Extensions to the Path Computation Element Communication Protocol (PCEP) for Point-to-Multipoint Traffic Engineering Label Switched Paths Abstract Point-to-point Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering Label Switched Paths (TE LSPs) may be established using signaling techniques, but their paths may first need to be determined. The Path Computation Element (PCE) has been identified as an appropriate technology for the determination of the paths of point-to-multipoint (P2MP) TE LSPs. This document describes extensions to the PCE communication Protocol (PCEP) to handle requests and responses for the computation of paths for P2MP TE LSPs. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.
