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]. 2. YANG Model (Tree Structure) module: ietf-wson-tunnel Lee, et al.

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) -------------------------------------------------------------------- 6.
