Introduction This document provides a YANG data model for the routing and wavelength assignment (RWA) Traffic Engineering (TE) topology in transparent 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]. [ITU-Tg6982] defines amplified multichannel dense wavelength division multiplexing applications with single channel optical interfaces. The YANG data model defined in this document refers to the standard application mode defined in [ITU-Tg6982]. What is not in scope of this document is both impairment-aware optical networks and flexi-grid. Refer to [I-D.ietf-ccamp-optical-impairment-topology-yang] for impairement- aware optical network topology model and [I-D.ietf-ccamp-flexigrid-yang] for flexi-grid optical network topology model. Zheng, et al. Expires November 9, 2020 [Page 2] Internet-Draft WSON Topology YANG Model May 2020 Additionally, transponders and resource blocks (e.g., 3R Regeneration) models are not in the scope of this document. This document defines one YANG model: ietf-wson-topology (Section 3). This document augments the generic TE topology draft [I-D.ietf-teas-yang-te-topo]. There are multiple applications for the 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 model is used by NETCONF [RFC6020], [RFC8341] or a RESTCONF [RFC8040] protocol. The YANG data model defined in this document conforms to the Network Management Datastore Architecture [RFC8342]. 1.1. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 1.2. Terminology and Notations 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 Zheng, et al. Expires November 9, 2020 [Page 3] Internet-Draft WSON Topology YANG Model May 2020 The terminology for describing YANG data models is found in [RFC7950]. 1.3. 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]. 1.4. Prefix 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 the following table. +-------------+-------------------------+------------------------+ | Prefix | YANG module | Reference | +-------------+-------------------------+------------------------+ | layer0-types| ietf-layer0-types |[ietf-ccamp-layer-types]| | wson | ietf-wson-topology | [RFCXXXX] | | nw | ietf-network | [RFC8345] | | nt | ietf-network-topology | [RFC8345] | | tet | ietf-te-topology |[ietf-teas-yang-te-topo]| +-------------+-------------------------+------------------------+ Note: The RFC Editor will replace XXXX with the number assigned to the RFC once this draft becomes an RFC. 2.

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]. The NETCONF Protocol over Secure Shell (SSH) [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. These are the subtrees and data nodes and their sensitivity/vulnerability: /nw:networks/nw:network/nw:network-types/tet:te-topology /nw:networks/nw:network/nt:link/tet:te/tet:te-link-attributes /nw:networks/nw:network/nw:node/nt:termination-point/tet:te /nw:networks/nw:network/.../tet:te-bandwidth/tet:technology /nw:networks/nw:network/nw:node/tet:te/.../tet:label-restriction /nw:networks/nw:network/nw:node/.../tet:te-label/tet:technology 5. 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-topology Registrant Contact: The IESG XML: N/A; the requested URI is an XML namespace. This document registers a YANG module in the YANG Module Names registry [RFC7950] and [RFC6020]. Zheng, et al.
