1. Introduction
This document provides a YANG data model for the routing and
wavelength assignment (RWA) Traffic Engineering (TE) topology in
wavelength switched optical networks (WSONs). The YANG model
described in this document is a WSON technology-specific Yang model
based on the information model developed in [RFC7446] and the two

Internet-Draft WSON YANG Model October 2018
encoding documents [RFC7581] and [RFC7579] that developed protocol
independent encodings based on [RFC7446].
This document augments the generic TE topology draft [TE-TOPO].
What is not in scope of this document is both impairment-aware WSON
and flex-grid.
This document defines two YANG models: ietf-wson-topology (Section
3) and ietf-layer0-types (Section 4).
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:
o client
o server
o augment
o data model
o data node
The following terms are defined in [RFC6241] and are not redefined
here:
o configuration data
o 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
chapter 2 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, as shown in Table 1.
+-------------+-------------------------+-----------------+
| Prefix | YANG module | Reference |
+-------------+-------------------------+-----------------+
| layer0-type | ietf-layer0-types | [RFCXXXX] |
| wson | ietf-wson-topology | [RFCXXXX] |
| nw | ietf-network | [RFC8345] |
| nt | ietf-network-topology | [RFC8345] |
| tet | ietf-te-topology | [TE-TOPO] |
+-------------+-------------------------+-----------------+
Table 1: Prefixes and corresponding YANG modules
Note: The RFC Editor will replace XXXX with the number assigned to
the RFC once this draft becomes an RFC.

5. 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.
6. IANA Considerations
