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 Lee, et al. Expires January 2020 [Page 2] Internet-Draft WSON YANG Model July 2019 two encoding documents [RFC7581] and [RFC7579] that developed protocol independent encodings based on [RFC7446]. [G.698.2] 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 [G.698.2]. What is not in scope of this document is both impairment-aware optical networks and flexi-grid. Refer to [Impairment] for impairement-aware optical network topology model and [flexi-grid] for flexi-grid optical network topology model. Additionally, resource block models (e.g., 3R Regeneration) is not also in the scope of this document, which will be addressed in a separate document. This document defines one YANG model: ietf-wson-topology (Section 3). This document augments the generic TE topology draft [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 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 January 2020 [Page 3] Internet-Draft WSON YANG Model July 2019 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]. 1.3. 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. 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 | [Layer0-Types] | | 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.

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 Lee, et al. Expires January 2020 [Page 67] Internet-Draft WSON YANG Model July 2019 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 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. 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 Network Configuration Access Control Model (NACM) [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. 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: /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/nw:node/tet:te/tet:te-node-attributes /te-connectivity-matrices/te-connectivity-matrix/tet:path- constraints/tet:te-bandwidth/tet:technology /nw:networks/nw:network/nw:node/tet:te /tet:tunnel-termination-point/tet:local-link-connectivities /tet:label-restrictions/tet:label-restriction Lee, et al.
