Path Computation Element Communication Protocol (PCEP) Requirements for Wavelength Switched Optical Network (WSON) Routing and Wavelength Assignment
draft-ietf-pce-wson-routing-wavelength-15
Technical Summary
This memo provides application-specific requirements for the Path
Computation Element communication Protocol (PCEP) for the support of
Wavelength Switched Optical Networks (WSON). Lightpath provisioning
in WSONs requires a routing and wavelength assignment (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 light
path computation. Requirements for PCEP extensions in support of
optical impairments will be addressed in a separate document.
Working Group Summary
There are some closely related I-Ds just coming out of CCAMP.
The PCE WG waited until those I-Ds had completed WG last
call in CCAMP to ensure compatibility. but there is no strong
dependency that requires this document to be held up or
reviewed at the same time as the other documents.
There was nothing contentious in the WG process.
Document Quality
This is a requirements specification and so not ripe for implementation.
Cyril Margaria & Ramon Casllas did useful LC reviews.

Julien Meuric is the Document Shepherd
