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

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.
