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.
This document is a product of the Path Computation Element Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
