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 [RFC7579] and [RFC7581] that
developed protocol independent encodings based on [RFC7446].
This document augments the generic TE tunnel model
[I-D.ietf-teas-yang-te].
1.1. Terminology
Refer to [RFC7446] and [RFC7581] for the key terms used in this
document.
The following terms are defined in [RFC7950] and are not redefined
here:
Lee, et al. Expires 11 January 2024 [Page 2]
Internet-Draft WSON Tunnel YANG July 2023
* client
* server
* augment
* data model
* data node
The following terms are defined in [RFC6241] and are not redefined
here:
* configuration data
* state data
The terminology for describing YANG data models is found in
[RFC7950].
1.2. Tree Diagram
A simplified graphical representation of the data model is used in
Section 3 of this this document. The meaning of the symbols in these
diagrams is defined in [RFC8340].
1.3. Prefixes in Data Node Names
In this document, names of data nodes and other data model objects
are prefixed using the standard prefix associated with the
corresponding YANG imported modules. The module ietf-layer0-types
specified in [RFC9093], ietf-layer1-types specified in
[I-D.ietf-ccamp-layer1-types], ietf-te-path-computation specified in
[I-D.ietf-teas-yang-path-computation] and ietf-te specified in
[I-D.ietf-teas-yang-te] are imported in this module.

the RFC once this draft becomes an RFC.
2. WSON Tunnel Model Description
2.1. Overview of WSON Tunnel Model
The WSON tunnel model is using TE tunnel [I-D.ietf-teas-yang-te] and
TE types [RFC8776] as a basic model and augment to the TE tunnel with
WSON-specific parameters, including the bandwidth information and
label information. It is also worth noting that the WSON tunnel
provisioning is usually based on the WSON topology. Therefore the
WSON tunnel model is usually used together with WSON topology model
specified in [RFC9094].
More scenarios and model applications can be found in
[I-D.ietf-ccamp-transport-nbi-app-statement] and
[I-D.ietf-teas-actn-yang]. The current model is following the YANG
language specification as [RFC7950], and the corresponding protocol
is recommended to be Netconf protocol in [RFC6241] or RESTconf
protocol in [RFC8040].
The YANG module ietf-wson-tunnel defined in this document conforms to
the Network Management Datastore Architecture (NMDA) defined in
[RFC8342].
2.2. WSON-specific Parameters in Tunnel Model
WSON specific parameters have been augmenting to the TE tunnel
models. The attributes on both of the source and destination need to
be configured when setting up the tunnel. Typical parameters,
including bandwidth and grid information, are required in the WSON
tunnel model. These parameters are consistent with the framework in
[RFC6163], and the specification in [RFC7579] and [RFC7581].
The WSON bandwidth information has been augmenting to various
sections of TE tunnel models, including tunnel bandwidth, primary
path bandwidth and so on. The WSON label information has been
augmenting to label hop of a group of routing objects and also LSPs.

5. Security Considerations
The YANG module specified in this document defines a schema for data
that is designed to be accessed via network management protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
[RFC8446].
Lee, et al. Expires 11 January 2024 [Page 38]
Internet-Draft WSON Tunnel YANG July 2023
The NETCONF protocol over Secure Shell (SSH) specification [RFC6242]
describes a method for invoking and running NETCONF within a Secure
Shell (SSH) session as an SSH subsystem. The NETCONF access control
model [RFC8341] provides the means to restrict access for particular
NETCONF or RESTCONF users to a preconfigured subset of all available
NETCONF or RESTCONF protocol operations and content.
There are a number of data nodes defined in this YANG module that are
writable/creatable/deletable (i.e., config true, which is the
default). These data nodes may be considered sensitive or vulnerable
in some network environments. Write operations (e.g., edit-config)
to these data nodes without proper protection can have a negative
effect on network operations. Considerations in Section 8 of
[I-D.ietf-teas-yang-te] are also applicable to the module defined in
this document.
Some of the readable data nodes in this YANG module may be considered
sensitive or vulnerable in some network environments. It is thus
important to control read access (e.g., via get, get-config, or
notification) to these data nodes. Considerations in Section 8 of
[I-D.ietf-teas-yang-te]are also applicable to the module defined in
this document.
Finally, the YANG module described in this document augments the
"ietf-te" YANG module [I-D.ietf-teas-yang-te] by adding data nodes.
The security considerations for the subtrees described in those RFCs
apply equally to the new data nodes that this module adds.
6. IANA Considerations
It is proposed that IANA should assign new URIs from the "IETF XML
Registry" [RFC3688] as follows:
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 following YANG modules in the YANG Module
Names registry [RFC7950].
