The IESG has received a request from the Common Control and Measurement Plane WG (ccamp) to consider the following document: - 'A Framework for the Control of Wavelength Switched Optical Networks (WSON) with Impairments' <draft-ietf-ccamp-wson-impairments-07.txt> as an Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2011-10-11. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract As an optical signal progresses along its path it may be altered by the various physical processes in the optical fibers and devices it encounters. When such alterations result in signal degradation, these processes are usually referred to as "impairments". These physical characteristics may be important constraints to consider when using a GMPLS control plane to support path setup and maintenance in wavelength switched optical networks. This document provides a framework for applying GMPLS protocols and the PCE architecture to support Impairment Aware Routing and Wavelength Assignment (IA-RWA) in wavelength switched optical networks. This document does not define optical data plane aspects; impairment parameters, measurement of, or assessment and qualification of a route, but rather it describes the architectural and information components for protocol solutions. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-ccamp-wson-impairments/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-ccamp-wson-impairments/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
