Hi CCAMPers, at the San Francisco meeting there were two actions for
RWA WSON (non-impairment case): (1) To look at how the WSON Framework and path computation Info Model could be generalized to other technologies. (2) To extend the WSON RWA Framework and models to apply to OEO switches, regenerators and similar systems. We've discussed (1) on this list and will be updating the WSON RWA Info model WG draft shortly. For (2) we decided to first put our ideas down in a separate draft covering how to support these extensions. We just published these as "WSON Signal Characteristics and Network Element Compatibility Constraints for GMPLS", draft-bernstein-ccamp-wson-signal-00.txt. (http://www.ietf.org/internet-drafts/draft-bernstein-ccamp-wson-signal-00.txt) The goal would be to merge this work into the RWA WSON Framework draft once we've had a discussion of this on the list. Your comments and feedback are invited! Abstract: While the current GMPLS WSON formalism can deal with many types of wavelength switching systems there is a desire to extend this control plane to include other common optical or hybrid electro optical systems such as OEO switches, regenerators, and wavelength converters. This document provides a WSON signal definition and characterization based on ITU-T interface and signal class standards and describes the signal compatibility constraints of this extended set of network elements. The signal characterization and network element compatibility constraints enable GMPLS routing and signaling to control these devices and PCE to compute optical light-paths subject to signal compatibility attributes.Best Regards Greg, Young and Ben Mack-Crane -- =================================================== Dr Greg Bernstein, Grotto Networking (510) 573-2237 |
