   A YANG Data Model for WSON (Wavelength Switched Optical Networks)
                     draft-ietf-ccamp-wson-yang-23

Abstract

   This document provides a YANG data model for the routing and
   wavelength assignment (RWA) TE topology in wavelength switched
   optical networks (WSONs).  The YANG data model defined in this
   document conforms to the Network Management Datastore Architecture
   (NMDA).

1.  Introduction

   This document provides a YANG data model for the routing and
   wavelength assignment (RWA) Traffic Engineering (TE) topology in
   transparent wavelength switched optical networks (WSONs).  The YANG
   model described in this document is a WSON 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].

   [ITU-Tg6982] defines amplified multichannel dense wavelength division
   multiplexing applications with single channel optical interfaces.
   The YANG data model defined in this document refers to the standard
   application mode defined in [ITU-Tg6982].

   What is not in scope of this document is both impairment-aware
   optical networks and flexi-grid.  Refer to
   [I-D.ietf-ccamp-optical-impairment-topology-yang] for impairement-
   aware optical network topology model and
   [I-D.ietf-ccamp-flexigrid-yang] for flexi-grid optical network
   topology model.
