Dear CCAMPers,

We have published an individual draft - Evaluation of Possible Interior Gateway Protocol Extensions for Wavelength Switching Optical Networks.
http://www.ietf.org/internet-draf/draft-li-ccamp-wson-igp-eval-00.txt

[WSON-FRAME] (http://www.ietf.org/internet-drafts/draft-bernstein-ccamp-wavelength-switched-02.txt) provides control plane models for key wavelength switched optical network subsystems and processes. Section 5.2 of [WSON-FRAME] describes the subsystem properties which may be conveyed via an Interior Gateway Protocol (IGP). 

This document discusses the set of Interior Gateway Protocol (IGP) requirements that would enable distributed light path computation in Wavelength Switched Optical Networks (WSON). An IGP impact analysis is also provided. According to the analysis, there is no significant impact on the IGP performance. 

Please be noted, not all the detailed wavelength information needs to be carried by IGP, in most cases, only the changes of the wavelength resource are advertised in the WSON. 

We appreciate your comments and suggestions!

Regards,

Dan Li
