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
   tunnel model in Traffic-Engineered network has been defined in both
   generic way and technology-specific way.  The generic model, which is
   the base TE tunnel YANG model, can be found at
   [I-D.ietf-teas-yang-te].  Technology-specific models, such as OTN/
   WSON tunnel model, have also been defined in
   [I-D.ietf-ccamp-otn-tunnel-model] and
   [I-D.lee-ccamp-wson-tunnel-model] respectively.  Corresponding tunnel
   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 tunnel, using
   YANG language defined in [RFC7950].  The model is augmenting the
   generic TE tunnel model, and can be used by applications exposing to
   a network controller via a REST interface.  Furthermore, it can be
