1.  Introduction

   OTN transport networks can carry various types of client services.
   In many cases, the client signal is carried over an OTN tunnel across
   connected domains in a multi-domain network.  These OTN services can
   either be transported or switched in the OTN network.  If an OTN
   tunnel is switched, then additional parameters need to be provided to
   create a Mux OTN service.

   This document provides YANG model for creating OTN tunnel.  The model
   augments the TE Tunnel model, which is an abstract model to create TE
   Tunnels.

2.  Model Overview

   This section provides an overview of the OTN Service Model.
