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
Lee, et al. Expires July 2018 [Page 5]
Internet-Draft WSON Tunnel Model January 2018
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)
