1. Introduction

   In order to provision an optical connection (an optical path)
   through a wavelength switched optical networks (WSONs) or spectrum
   switched optical networks (SSONs), a combination of path continuity,
   resource availability, and impairment constraints must be met to
   determine viable and optimal paths through the network. The
   determination of appropriate paths is known as Impairment-Aware
   Routing and Wavelength Assignment (IA-RWA) [RFC6566] for WSON, while
   it is known as IA-Routing and Spectrum Assigment (IA-RSA) for SSON.

Internet-Draft   Optical Impairment-Aware YANG Model       October 2018

   This document provides a YANG data model for the impairment-aware
   Traffic Engineering (TE) topology in WSONs and SSONs. The YANG model
   described in this document is a WSON/SSON technology-specific Yang
   model based on the information model developed in [RFC7446] and the
   two encoding documents [RFC7581] and [RFC7579] that developed
   protocol independent encodings based on [RFC7446].

   The intent of this document is to provide a Yang data model, which
