1.  Introduction

   OTN transport networks, specified in [ITU-Tg709], 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.

2.  Terminology and Notations

   A simplified graphical representation of the data model is used in
   this document.  The meaning of the symbols in the YANG data tree
   presented later in this draft is defined in [RFC8340].  They are
   provided below for reference.

   o  Brackets "[" and "]" enclose list keys.

   o  Abbreviations before data node names: "rw" means configuration
      (read-write) and "ro" state data (read-only).

   o  Symbols after data node names: "?" means an optional node, "!"
      means a presence container, and "*" denotes a list and leaf-list.
