Applicability of the Path Computation Element to Inter-area and Inter-AS MPLS and GMPLS Traffic Engineering

Abstract

The Path Computation Element (PCE) may be used for computing services that traverse multi-area and multi-AS Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineered (TE) networks. This document examines the applicability of the PCE architecture, protocols, and protocol extensions for computing multi-area and multi- AS paths in MPLS and GMPLS networks.
