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 Lee, et al. Expires August 2018 [Page 2] 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]. Lee, et al.

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. 2.

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.
