The IESG has approved the following document: - 'PCEP Requirements for WSON Routing and Wavelength Assignment' (draft-ietf-pce-wson-routing-wavelength-15.txt) as Informational RFC This document is the product of the Path Computation Element Working Group. The IESG contact persons are Adrian Farrel and Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pce-wson-routing-wavelength/ 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. Personnel Julien Meuric is the Document Shepherd Adrian Farrel is the Responsible Area Director
