    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].

2.  Encoding

2.1.  Optical Parameter

   The OPTICAL_PARAM is defined as a sub TLV object.
