       Information Encoding for WSON with Impairments Validation
                draft-martinelli-ccamp-wson-iv-encode-03

Abstract

   Impairment-Aware (IA) Routing and Wavelength Assignment (RWA)
   function might be required in Wavelength Switched Optical Networks
   (WSON) that already support RWA.  This document defines proper
   encoding to support this operation.  It goes in addition to the
   available impairment-free 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
   can be used in related protocol extensions.

1.  Introduction

   In case of WSON where optical impairments play a significant role,
   the framework document [RFC6566] defines related control plane
   architectural options for Impairment Aware Routing and Wavelength
   Assignment (IA-RWA).  This document provides a suitable encoding for
   the related WSON impairment information model as 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.
