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 + data model described in this document is a WSON technology-specific + YANG data 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]. + + Neither impairment-aware optical networks nor flexi-grid are in scope + for this document. Refer to [OPT-IMPAIR-AWARE-YANG] for the + impairment-aware optical network topology model and [FLEXI-GRID-YANG] + for the flexi-grid optical network topology model. + + Additionally, neither transponder models nor resource block models + (e.g., 3R) are in scope for this document. + + This document defines one YANG module: "ietf-wson-topology" + (Section 3). This document augments the generic TE topology + specification [RFC8795]. + + 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 data 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. 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: + + * client + + * server + + * augment + + * data model + + * data node + + The following terms are defined in [RFC6241] and are not redefined + here: + + * configuration data + + * 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 + Section 2 of this document. The meaning of the symbols in these + diagrams is defined in [RFC8340]. + +1.3. 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 | + +==========+=======================+===========+ + | l0-types | ietf-layer0-types | [RFC9093] | + +----------+-----------------------+-----------+ + | wsont | ietf-wson-topology | RFC 9094 | + +----------+-----------------------+-----------+ + | nw | ietf-network | [RFC8345] | + +----------+-----------------------+-----------+ + | nt | ietf-network-topology | [RFC8345] | + +----------+-----------------------+-----------+ + | tet | ietf-te-topology | [RFC8795] | + +----------+-----------------------+-----------+ + + Table 1: Data Node Names + +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) specification [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. Considerations in Section 8 of + [RFC8795] are also applicable to the module defined in this document. + + 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 + [RFC8795] are also applicable to the module defined in this document. + + Finally, the YANG module described in this document augments the + "ietf-network" YANG module [RFC8345] and the "ietf-te-topology" YANG + module [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. + +5.
