1. Introduction

   This document provides a YANG data model for WSON tunnel model. The
   YANG model described in this document is a WSON technology-specific
   Yang Tunnel model based on the information model developed in
   [RFC7446] and the two encoding documents [RFC7581] and [RFC7579]
   that developed protocol independent encodings based on [RFC7446].

   This document augments the generic TE tunnel model [TE-Tunnel].

4. Security Considerations

   The configuration, state, and action data defined in this document
   are designed to be accessed via a management protocol with a secure
   transport layer, such as NETCONF [RFC6241].  The NETCONF access
   control model [RFC6536] provides the means to restrict access for
   particular NETCONF users to a preconfigured subset of all available
   NETCONF protocol operations and content.

   A number of configuration data nodes defined in this document are
   writable/deletable (i.e., "config true") These data nodes may be
   considered sensitive or vulnerable in some network environments.


5. IANA Considerations

   This document registers the following namespace URIs in the IETF XML
   registry [RFC3688]:

   --------------------------------------------------------------------
   URI: urn:ietf:params:xml:ns:yang:ietf-wson-tunnel
   Registrant Contact: The IESG.
   XML: N/A, the requested URI is an XML namespace.
   --------------------------------------------------------------------

   This document registers the following YANG modules in the YANG
   Module

   Names registry [RFC7950]:

   --------------------------------------------------------------------
   name:         ietf-wson-tunnel
   namespace:    urn:ietf:params:xml:ns:yang:ietf-wson-tunnel
   reference:    RFC XXXX (TDB)
