Encoding for WSON Information Model with Impairments Validation.
draft-martinelli-ccamp-wson-iv-encode-01
Abstract
This document defines proper encoding for the Information Model to
support Impairment-Aware (IA) Routing and Wavelength Assignment (RWA)
function. This operation might be required in Wavelength Switched
Optical Networks (WSON) that already support RWA, encoding defined
here goes in addition to available WSON encoding and it is fully
compatible with it.
As the information model, the encoding is independent from control
plane architectures and protocol implementations. Its definitions
must be reused in related protocol extensions.

Internet-Draft Encoding WSON Info Model with Impairments February 2013
1. Introduction
In case of WSON where optical impairments plays a significant role,
the framework document [RFC6566] defines related control plane
architectural options for an Impairment Aware routing and wavelength
assignment (IA-RWA). This document provides a suitable encoding for
the related WSON Impairment Information Model defined
[I-D.martinelli-ccamp-wson-iv-info].
This document directly refers to ITU recommendations [ITU.G680] and
[ITU.G697] as already detailed in the information model.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
