1. 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 (":").

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.

6. 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:

Editors note: we are using simplified description by folding similar

7. 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
