Applicability of the Path Computation Element to Inter-area and Inter-AS MPLS and GMPLS Traffic Engineering, December 2019
Discuss this RFC: Send questions or comments to email@example.com
The Path Computation Element (PCE) may be used for computing services that traverse multi-area and multi-Autonomous System (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.
