                 draft-zheng-ccamp-client-topo-yang-04

Abstract

   A transport network is a server-layer network to provide connectivity
   services to its client.  In this draft the topology of client is
   described.

1.  Introduction

   A transport network is a server-layer network designed to provide
   connectivity services for a client-layer network to carry the client
   traffic transparently across the server-layer network resources.  The
   topology model in Traffic-Engineered network has been defined in both
   generic way and technology-specific way.  The generic model, which is
   the base TE YANG model, can be found at [I-D.ietf-teas-yang-te-topo].
   Technology-specific models, such as OTN/WSON topology model, have
   also been defined in [I-D.ietf-ccamp-otn-topo-yang] and
   [I-D.ietf-ccamp-wson-yang] respectively.  Corresponding topology on
   client-layer is also required, to have a complete topology view from
   the perspective of network controllers.

   This document defines a data model of all client-layer Topology,
   using YANG language defined in [RFC7950].  The model is augmenting
   the generic TE topology model, and can be used by either applications
   exposing to a network controller or among controllers.  Furthermore,
