The Path Computation Element Communication Protocol Extension for Wavelength Switched Optical Network Routing and Wavelength Assignment
RFC 8780, “The Path Computation Element Communication Protocol Extension for Wavelength Switched Optical Network Routing and Wavelength Assignment”, is a Proposed Standard document published in July 2020 by Y. Lee, R. Casellas. It has since been updated by RFC 9756. The canonical text is published by the RFC Editor.
Abstract
This document provides Path Computation Element Communication Protocol (PCEP) extensions for the support of Routing and Wavelength Assignment (RWA) in Wavelength Switched Optical Networks (WSONs). Path provisioning in WSONs requires an RWA process. From a path computation perspective, wavelength assignment is the process of determining which wavelength can be used on each hop of a path and forms an additional routing constraint to optical path computation.
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.
