Applicability of the Path Computation Element to Point-to- Multipoint MPLS and GMPLS Traffic Engineering

Overview

RFC 5671, “Applicability of the Path Computation Element to Point-to- Multipoint MPLS and GMPLS Traffic Engineering”, is an Informational document published in October 2009 by S. Yasukawa, A. Farrel. The canonical text is published by the RFC Editor.

Abstract

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.
