Introduction OTN transport networks, specified in [ITU-Tg709], can carry various types of client signals. In many cases, the client signal is carried over an OTN tunnel across connected domains in a multi-domain network. This document provides YANG model for creating OTN tunnel. The model augments the TE Tunnel model. 2. Terminology and Notations A simplified graphical representation of the data model is used in this document. The meaning of the symbols in the YANG data tree presented later in this draft is defined in [RFC8340]. They are provided below for reference. o Brackets "[" and "]" enclose list keys. o Abbreviations before data node names: "rw" means configuration (read-write) and "ro" state data (read-only). o Symbols after data node names: "?" means an optional node, "!" means a presence container, and "*" denotes a list and leaf-list. o Parentheses enclose choice and case nodes, and case nodes are also marked with a colon (":"). Zheng, et al. Expires March 23, 2021 [Page 2] Internet-Draft OTN Tunnel YANG Model September 2020 o Ellipsis ("...") stands for contents of subtrees that are not shown. o More OTN specific terms can be found in [I-D.ietf-ccamp-otn-topo-yang]. 3. OTN Tunnel Model Description 3.1. Overview of OTN Tunnel Model The OTN tunnel model is using TE tunnel [I-D.ietf-teas-yang-te] as a basic model and augment to the TE tunnel with OTN-specific parameters, including the bandwidth information and label information. It is also worth noting that the OTN tunnel provisioning is usually based on the OTN topology. Therefore the OTN tunnel model is usually used together with OTN topology model specified in [I-D.ietf-ccamp-otn-topo-yang]. The OTN tunnel model also imports a few type modules, including ietf-layer1-types, ietf- te-types and ietf-inet-types. The OTN-specific attributes, such as Tributary Slot (TS), Tributary Port Number (TPN), are specified in the module ietf-layer1-types in [I-D.ietf-ccamp-layer1-types] and used in this document. 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-otn-tunnel defined in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342]. 3.2. OTN-specific Parameters in Tunnel Model OTN 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 client signal, TPN, TSG and corresponding tributary slot information, are required in the OTN tunnel model. These parameters are consistent with the framework in [RFC7062], and the specification in [RFC7138] and [RFC7139]. The OTN bandwidth information has been augmenting to various sections of TE tunnel models, including tunnel bandwidth, primary path bandwidth and so on. The OTN label information has been augmenting to label hop of a group of routing objects and also LSPs. Zheng, et al.

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 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: /te:te/te:tunnels/te:tunnel /te:te/../te:te-bandwidth/te:technology /te:te/../te:type/te:label/te:label-hop/te:te-label/te:technology /te:te/../te:label-restrictions/te:label-restriction/te:label-start/ te:te-label/te:technology /te:te/../te:label-restrictions/te:label- restriction/te:label-end/te:te-label/te:technology /te:te/../te:label-restrictions/te:label-restriction/ Editors note: we are using simplified description by folding similar branches to avoid repetation. 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. These are the subtrees and data nodes and their sensitivity/vulnerability: Zheng, et al.

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-otn-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]. name: ietf-otn-tunnel namespace: urn:ietf:params:xml:ns:yang:ietf-otn-tunnel prefix: otn-tunnel reference: RFC XXXX 8.
