Body |
The CCAMP working group of the IETF thanks ITU-T SG15 for sharing their "Optical Transport Networks & Technologies Standardization Work Plan" in a liaison dated February 29th, 2008. We have no specific comments on the plan, but would like to draw your attention to work currently in progress within CCAMP to extend the GMPLS control plane for use in Wavelength Switched Optical Networks (WSONs). We have three working group drafts related to this topic as follows: Framework for GMPLS and PCE Control of Wavelength Switched Optical Networks (WSON) http://www.ietf.org/internet-drafts/draft-ietf-ccamp-wavelength-switched-framework-00.txt Generalized Labels for G.694 Lambda-Switching Capable Label Switching Routers http://www.ietf.org/internet-drafts/draft-ietf-ccamp-gmpls-g-694-lambda-labels-02.txt Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks http://www.ietf.org/internet-drafts/draft-ietf-ccamp-rwa-info-00.txt At the moment, CCAMP has decided to split the effort into two parts: 1. Work on the Routing Wavelength Assignment (RWA) problem 2. Work on optical-impairment-based networking At the moment effort is only being expended on the first of these, with the problems of handling optical impairments being deferred for future work. Please note that, at such a time that CCAMP does work with optical impairments, it is not our intention to define impairments, but we will defer to the ITU-T on this. Lastly, it has been observed in the course of our work that the modeling of asymmetric switches such as ROADMs may be an area that the ITU-T would like to work on.
