Introduction OTN transport networks can carry various types of client services. In many cases, the client signal is carried over an OTN tunnel across connected domains in a multi-domain network. These OTN services can either be transported or switched in the OTN network. If an OTN tunnel is switched, then additional parameters need to be provided to create a Mux OTN service. 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 Zheng, et al. Expires December 21, 2018 [Page 2] Internet-Draft OTN Tunnel YANG Model June 2018 [I-D.ietf-netmod-yang-tree-diagrams]. 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 (":"). o Ellipsis ("...") stands for contents of subtrees that are not shown. 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]. 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]. 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 Zheng, et al. Expires December 21, 2018 [Page 3] Internet-Draft OTN Tunnel YANG Model June 2018 bandwidth and so on. The OTN label information has been augmenting to label hop of a group of routing objects and also LSPs. 3.3. OTN Path Compute RPC Similarly with TE tunnel, a 'compute-only' mode of OTN tunnel model is also supported by specifing a Remote Procedural Call (RPC). On receiving this RPC, the provider is expected to compute the available path subject to the constraints specified in RPC and feedback to the client without any changing of the OTN network. Given the OTN tunnel computed, the client may query and/or subscribe on the tunnel to be notified whenever it changes. 4.
