Hi PCErs, We have updated PCEP extension for WSON RWA.
Major changes: - Signal compatibility aligns with optical signal class encoding per [WSON-Encode] - Explicit Wavelength Assignment uses GMPLS Explicit Label Control (ELC) mechanism per [RFC 4003] and [PCEP for GMPLS]. - Distributed Wavelength Assignment (from PCE -> PCC) points to Cyril's LSPA-ERO draft proposed in CCAMP. Basically, we have tried to align existing/proposed Generic method for GMPLS as much as possible while addressing WSON specific issues in an effort to avoid duplication with [PCEP for GMPLS] and other GMPLS-based solutions [LSPA-ERO] & [RFC 4003]. Thanks.

Filename: draft-lee-pce-wson-rwa-ext Revision: 05 Title: PCEP Extension for WSON Routing and Wavelength Assignment Creation date: 2013-02-06 WG ID: Individual Submission Number of pages: 22 URL: http://www.ietf.org/internet-drafts/draft-lee-pce-wson-rwa-ext-05.txt Status: http://datatracker.ietf.org/doc/draft-lee-pce-wson-rwa-ext Htmlized: http://tools.ietf.org/html/draft-lee-pce-wson-rwa-ext-05 Diff: http://www.ietf.org/rfcdiff?url2=draft-lee-pce-wson-rwa-ext-05 Abstract: This draft provides the Path Computation Element communication Protocol (PCEP) extensions for the support of Routing and Wavelength Assignment (RWA) in 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.
