Path Computation Element Communication Protocol Extensions for Stateful PCE Usage in GMPLS-Controlled Networks
RFC 9504, “Path Computation Element Communication Protocol Extensions for Stateful PCE Usage in GMPLS-Controlled Networks”, is a Proposed Standard document published in December 2023 by Y. Lee, H. Zheng, O. Gonzalez de Dios, V. Lopez, Z. Ali. It has since been updated by RFC 9756. The canonical text is published by the RFC Editor.
Abstract
The Path Computation Element Communication Protocol (PCEP) has been extended to support stateful PCE functions where the stateful PCE maintains information about paths and resource usage within a network; however, these extensions do not cover all requirements for GMPLS networks.
This document provides the extensions required for PCEP so as to enable the usage of a stateful PCE capability in GMPLS-controlled networks.
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.
