      <t>
 This document provides a YANG data model for the routing and wavelength assignment (RWA) Traffic Engineering (TE) topology in transparent wavelength switched optical networks Wavelength Switched Optical Networks (WSONs). The YANG data model described in this document is a WSON technology-specific YANG data model based on the information model developed in <xref target="RFC7446" /> format="default"/> and the two encoding documents <xref (<xref target="RFC7581" /> format="default"/> and <xref target="RFC7579" /> format="default"/>) that developed protocol independent protocol-independent encodings based on <xref target="RFC7446" />. format="default"/>.
      </t>
      <t>
  <xref target="ITU-Tg6982" /> format="default"/> defines amplified multichannel dense wavelength division multiplexing applications with single channel single-channel optical interfaces.  The YANG data model defined in this document refers to the standard application mode defined in <xref target="ITU-Tg6982" />. format="default"/>.
      </t>
      <t>
  What is not in scope of this document is both
  Neither impairment-aware optical
  networks and flexi-grid. nor flexi-grid are in scope for this document. Refer to <xref
  target="I-D.ietf-ccamp-optical-impairment-topology-yang" /> format="default"/>
  for the impairment-aware optical network topology model and <xref
  target="I-D.ietf-ccamp-flexigrid-yang" /> format="default"/> for the flexi-grid
  optical network topology model.
      </t>
      <t>
  Additionally, transponders and neither transponder models nor resource blocks  (e.g., 3R Regeneration) block models (e.g., 3R) are not in the scope of for this document.
      </t>

      <t>
  This document defines one YANG model: ietf-wson-topology (Section 3). module: "ietf-wson-topology" (<xref target="code"/>). This document augments the generic TE topology draft specification <xref target="RFC8795" />. format="default"/>.
      </t>
      <t>
  There are multiple applications for the yang YANG data model defined in this document. For example, nodes within the network can use the data model to capture their understanding of the overall WSON topology and expose it to a controller.  A controller can further propagate the topology to other controllers. The YANG data model is used by NETCONF <xref target="RFC6020" />, format="default"/> <xref target="RFC8341" /> format="default"/> or a RESTCONF <xref target="RFC8040" /> format="default"/> protocol. The YANG data model defined in this document conforms to the Network Management Datastore Architecture <xref target="RFC8342" />. format="default"/>.

    "This module provides a YANG data model for the routing and
     wavelength assignment (RWA) Traffic Engineering (TE)
     topology in wavelength switched optical networks Wavelength Switched Optical Networks (WSONs).
     The YANG data model described in this document is a WSON
     technology-specific YANG data model augmenting the generic TE
     topology module (ietf-te-topology) based on the information
     model developed in RFC 7446 and the two encoding documents
     RFC 7579 and RFC 7581.

<!-- [rfced]  Authors and AD*:  Security Considerations:
The second, third, and fourth paragraphs of this section do not match
the guidance provided on
<https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines>.
Please review this page, and let us know how/if this section should
be updated.

Authors, please clarify the meaning of the following sentence
(which appears twice):

Original ("[RFC8795]are" has been corrected):
   Considerations in Section 8 of
   [RFC8795]are also applicable to their subtrees in the module defined
   in this document.
-->

      <t>
   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 <xref target="RFC6241" /> format="default"/> or RESTCONF <xref target="RFC8040" />. format="default"/>.  The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) <xref target="RFC6242" />. format="default"/>.  The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS <xref target="RFC8446" />. format="default"/>.
      </t>
      <t>
  The NETCONF Protocol protocol over Secure Shell (SSH) specification <xref target="RFC6242" /> format="default"/> describes a method for invoking and running NETCONF within a Secure Shell (SSH) session as an SSH subsystem.  The NETCONF access control model <xref target="RFC8341" /> format="default"/> 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.
      </t>
      <t>
  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 <xref target="RFC8795" />are sectionFormat="of" section="8" format="default"/> are also applicable to their subtrees in the module defined in this document.
      </t>
      <t>
  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 <xref target="RFC8795" />are sectionFormat="of" section="8"  format="default"/> are also applicable to their subtrees in the module defined in this document.
      </t>
<t>
Finally, the YANG module described in this document augments the "ietf-network" YANG module <xref target="RFC8345"/> and the "ietf-te-topology" YANG module <xref target="RFC8795"/> 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.
