            A YANG Data Model for Flexi-Grid Media Channels
            draft-ietf-ccamp-flexigrid-media-channel-yang-03

Abstract

   This document defines a YANG model for managing flexi-grid optical
   media channels, complementing the information provided by the flexi-
   grid topology model.

   The YANG data model defined in this document conforms to the Network
   Management Datastore Architecture (NMDA).

1.  Introduction

   Transport networks are evolving from current DWDM systems towards
   elastic optical networks, based on flexi-grid transmission and
   switching technologies [RFC7698].  Such technology aims at increasing
   both transport network scalability and flexibility, allowing the
   optimization of bandwidth usage.

   While [I-D.ietf-ccamp-flexigrid-yang] focuses on flexi-grid objects
   such as nodes, transponders and links, this document presents a YANG
   [RFC7950] model for the flexi-grid media-channel.  This YANG module
   defines the whole path from a source transponder or node to the
   destination through a number of intermediate nodes in the flexi-grid
