Extensions to the Path Computation Element Communication Protocol for Inter-Layer MPLS and GMPLS Traffic Engineering
RFC 8282, “Extensions to the Path Computation Element Communication Protocol for Inter-Layer MPLS and GMPLS Traffic Engineering”, is a Proposed Standard document published in December 2017 by E. Oki, T. Takeda, A. Farrel, F. Zhang. 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.
MPLS and GMPLS networks may be constructed from layered service networks. It is advantageous for overall network efficiency to provide end-to-end traffic engineering across multiple network layers through a process called inter-layer traffic engineering. PCE is a candidate solution for such requirements.
The PCE Communication Protocol (PCEP) is designed as a communication protocol between Path Computation Clients (PCCs) and PCEs. This document presents PCEP extensions for inter-layer traffic engineering.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
