Information Model for Wavelength Switched Optical Networks (WSON) with
Optical Impairments Validation.
draft-martinelli-ccamp-wson-iv-info-01
Abstract
This document defines the Information Model to support Impairment-
Aware (IA) Routing an Wavelength Assignment (RWA) function. This
operation might be required in Wavelength Switched Optical Networks
(WSON) that already support RWA and the Information model defined
here goes in addition and it is fully compatible with the already
defined information model for WSON.
This information model shall support all control plane architectural
options defined for WSON with impairment validation.

Internet-Draft WSON Impairments Information Model February 2013
1. Introduction
In the context of Wavelength Switched Optical Network (WSON),
[RFC6163] defines the basic framework for a GMPLS control plane. The
associated info model [I-D.ietf-ccamp-rwa-info] defines all
parameters required for the related RWA process. These references
are the foundation but they do not consider the Optical Impairment
case.
In case of WSON where optical impairments plays a significant role,
