1. 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

[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.
