Path Computation Element Communication Protocol Extensions for Associating Working and Protection Label Switched Paths with Stateful PCE
RFC 8745, “Path Computation Element Communication Protocol Extensions for Associating Working and Protection Label Switched Paths with Stateful PCE”, is a Proposed Standard document published in March 2020 by H. Ananthakrishnan, S. Sivabalan, C. Barth, I. Minei, M. Negi. It has since been updated by RFC 9756. The canonical text is published by the RFC Editor.
Abstract
An active stateful Path Computation Element (PCE) is capable of computing as well as controlling via Path Computation Element Communication Protocol (PCEP) Multiprotocol Label Switching Traffic Engineering (MPLS-TE) Label Switched Paths (LSPs). Furthermore, it is also possible for an active stateful PCE to create, maintain, and delete LSPs. This document defines the PCEP extension to associate two or more LSPs to provide end-to-end path protection.
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.
