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, which is an abstract model to create TE Tunnels. 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 [I-D.ietf-netmod-yang-tree-diagrams]. They are provided below for reference. Zheng, et al. Expires May 3, 2018 [Page 2] Internet-Draft OTN Tunnel YANG Model October 2017 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. Model Overview 3.1.

Client Signal 1. Client Signal 2. Tributary Port Number 2. Tributary Port Number 3. Tributary Slot Granularity 3. Tributary Slot Granularity 4. Tributary Slots 4. Tributary Slots Figure 1: OTN Mux Service in a multi-domain network topology Figure 1 shows a multi-domain OTN network with three domains. In this example, user wants to setup an end-to-end OTN service that passes through Domain-2. In order to create an OTN mux service in Domain-2, user will need to specify the exact details of the client side LO-ODU on NE2 and NE3, so that these service endpoints can be paired with the LO-ODU endpoints on NE1 and NE4, respectively. Zheng, et al. Expires May 3, 2018 [Page 3] Internet-Draft OTN Tunnel YANG Model October 2017 Let's assume that ODU4 is the client side HO-ODU on NE2 and NE3, and the client signal is ODU2. User will need to specify the OTN client signal (ODU2 in this example), the Tributary Port Number (TPN), Tributary Slot Granularities (TSG) and tributary slots to be used. As shown in the figure above, these service parameters must be the same between NE1 and NE2, and NE3 and NE4. Once the OTN Mux service is setup in Domain-2, the incoming signal from either NE1 and/or NE4 will be switched inside Domain-2, and delivered to NE at the other end. 3.2. Bookended and Non-BookEnded OTN Tunnel OTN tunnel model provides support for both bookended and non- bookended OTN tunnels. For bookended tunnels, the same client signal is present on source and destination endpoints. For example, ODU2e bookended tunnel will have the same ODU2e client signal at both source and destination endpoints. For non-bookended tunnels, different client signals are present on source and destination endpoints. For example, the client signal can be ODU2e on the source endpoint and the handoff at the destination can be 10GbE-LAN client signal. 3.3. Network and Client side tunnel services The OTN tunnel model provides support for both network to network and client to client tunnels. For network to network tunnel, network termination points on source and destination node represent source and destination endpoints. For client to client tunnel, client termination points on source and destination node represent source and destination endpoints. If a client to client tunnel needs to use one or more HO (or server) network to network tunnels, ERO and routing constraints, defined in the base TE model, can be used to route the client tunnel over one or more server tunnels. 3.4.
