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
encoding documents [RFC7581] and [RFC7579] that developed protocol
independent encodings based on [RFC7446].
This document augments the generic TE topology draft [TE-TOPO].
Lee, et al. Expires May 2018 [Page 2]
Internet-Draft WSON YANG Model November 2018
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.

"This module 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 augmenting the generic TE
topology module [TE-TOPO] based on the information model
developed in [RFC7446] and the two encoding documents
[RFC7581] and [RFC7579] that developed protocol independent
encodings based on [RFC7446].

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.
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. These are the subtrees and
data nodes and their sensitivity/vulnerability:
