                  draft-ietf-ccamp-otn-tunnel-model-12

Abstract

   This document describes the YANG data model for tunnels in OTN TE
   networks.  The model can be used to do the configuration in order to
   establish the tunnel in OTN network.  This work is independent with
   the control plane protocols.  The YANG data model defined in this
   document conforms to the Network Management Datastore Architecture
   (NMDA).

1.  Introduction

   OTN transport networks, specified in [ITU-Tg709], can carry various
   types of client signals.  In many cases, the client signal is carried
   over an OTN tunnel across connected domains in a multi-domain
   network.

   This document provides YANG model for creating OTN tunnel.  The model
   augments the generic TE Tunnel model specified in
   [I-D.ietf-teas-yang-te].

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, "!"
