Page th IETF – Anaheim, California, March 2010 Information for RWA in WSON Contains high level path computation info model for WSONs –Not a management info model, but a path computation information model Same scope of applicability as WSON RWA Framework document

Page th IETF – Anaheim, California, March 2010 Changes Changes from 04 –Removed encoding specific text from Section 4.1. –Removed encoding specific text from Section 3.4. Changes from 05 –Renumbered sections for clarity. –Separated Generic model from WSON specific model –Added signal compatibility model (WSON specific) Changes from 06 –Simplified information model for WSON specifics, by combining similar fields and introducing simpler aggregate information elements.
