	Title           : Information Model for Impaired Optical Path Validation
	Author(s)       : G. Bernstein, C. Systems

This document provides an information model for the optical 
impairment characteristics of optical network elements for use in 
GMPLS/PCE control plane protocols and mechanisms. This information 
model supports Impairment Aware Routing and Wavelength Assignment 
(IA-RWA) in optical networks in which path computation and optical 
path validation are essential components. This is not a general 
network management information model.  

This model is based on ITU-T defined optical network element 
characteristics as given in ITU-T recommendation G.680 and related 
specifications. This model is intentionally compatible with a 
previous impairment free optical information model used in optical 
path computations and wavelength assignment.
