Introduction This document provides a YANG data model for WSON tunnel model. The YANG model described in this document is a WSON technology-specific Yang Tunnel model based on the information model developed in [RFC7446] and the two encoding documents [RFC7579] and [RFC7581] that developed protocol independent encodings based on [RFC7446]. This document augments the generic TE tunnel model [I-D.ietf-teas-yang-te]. 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 Lee, et al. Expires April 25, 2022 [Page 2] Internet-Draft WSON Tunnel YANG October 2021 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 Section 3 of this this document. The meaning of the symbols in these diagrams is defined in [RFC8340]. 1.3. 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. The module ietf-layer0-types specified in [RFC9093], ietf-layer1-types specified in [I-D.ietf-ccamp-layer1-types], ietf-te-path-computation specified in [I-D.ietf-teas-yang-path-computation] and ietf-te specified in [I-D.ietf-teas-yang-te] are imported in this module. +-------------+-------------------+------------------------------+ | Prefix | YANG module | Reference | +-------------+-------------------+------------------------------+ | layer0-types|ietf-layer0-types |[RFC 9093] | | layer1-types|ietf-layer1-types |[I-D.ietf-ccamp-layer1-types] | | tepc |ietf-te-path-computation |[I-D.ietf-teas-yang-path-computation]| | te | ietf-te |[I-D.ietf-teas-yang-te] | | wson-tunnel | ietf-wson-tunnel |[RFC XXXX] | +-------------+-------------------+------------------------------+ Note: The RFC Editor will replace XXXX with the number assigned to the RFC once this draft becomes an RFC. Lee, et al. Expires April 25, 2022 [Page 3] Internet-Draft WSON Tunnel YANG October 2021 2. WSON Tunnel Model Description 2.1. Overview of WSON Tunnel Model The WSON tunnel model is using TE tunnel [I-D.ietf-teas-yang-te] and TE types [RFC8776] as a basic model and augment to the TE tunnel with WSON-specific parameters, including the bandwidth information and label information. It is also worth noting that the WSON tunnel provisioning is usually based on the WSON topology. Therefore the WSON tunnel model is usually used together with WSON topology model specified in [RFC9094]. More scenarios and model applications can be found in [I-D.ietf-ccamp-transport-nbi-app-statement] and [I-D.ietf-teas-actn-yang]. The current model is following the YANG language specification as [RFC7950], and the corresponding protocol is recommended to be Netconf protocol in [RFC6241] or RESTconf protocol in [RFC8040]. The YANG module ietf-wson-tunnel defined in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342]. 2.2. WSON-specific Parameters in Tunnel Model WSON specific parameters have been augmenting to the TE tunnel models. The attributes on both of the source and destination need to be configured when setting up the tunnel. Typical parameters, including bandwidth and grid information, are required in the WSON tunnel model. These parameters are consistent with the framework in [RFC6163], and the specification in [RFC7579] and [RFC7581]. The WSON bandwidth information has been augmenting to various sections of TE tunnel models, including tunnel bandwidth, primary path bandwidth and so on. The WSON label information has been augmenting to label hop of a group of routing objects and also LSPs. 3.

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]. Lee, et al. Expires April 25, 2022 [Page 38] Internet-Draft WSON Tunnel YANG October 2021 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 [I-D.ietf-teas-yang-te] 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 [I-D.ietf-teas-yang-te]are also applicable to the module defined in this document. Finally, the YANG module described in this document augments the "ietf-te" YANG module [I-D.ietf-teas-yang-te] 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. 6. 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-tunnel Registrant Contact: The IESG XML: N/A; the requested URI is an XML namespace. This document registers following YANG modules in the YANG Module Names registry [RFC7950]. Lee, et al.
