A YANG Data Model for Optical Transport Network Topology
draft-ietf-ccamp-otn-topo-yang-17
Abstract
This document describes a YANG data model to describe the topologies
of an Optical Transport Network (OTN). It is independent of control

interact with a transport domain controller, for OTN topology-related
operations such as obtaining the relevant topology resource
information.

1. Introduction
A transport network is a server-layer network designed to provide
connectivity services for a client-layer network to carry the client
traffic transparently across the server-layer network resources. A
transport network typically utilizes several different transport
technologies such as the Optical Transport Networks (OTN) or packet
transport such as provided by the MPLS-Transport Profile (MPLS-TP).

Internet-Draft OTN Topology YANG Model July 2023
This document defines a data model of an OTN network topology, using
YANG [RFC7950]. The model can be used by an application
communicating with a transport controller. Furthermore, it can be
used by an application for the following purposes (but not limited
to):
* To obtain a whole view of the network topology information of its
interest;
* To receive notifications with regard to the information change of
the OTN topology;
* To enforce the establishment and update to the network topology
with the characteristics specified in the data model;
The YANG model defined in this document is independent of control
plane protocols and captures topology related information pertaining
to an Optical Transport Networks (OTN) electrical layer, as the scope
specified by [RFC7062] . Furthermore, it is not a stand-alone model,
but augments from the TE topology YANG model defined in [RFC8795],
and importing from the generic Layer 1 types defined in
[I-D.ietf-ccamp-layer1-types]. Following TE topology YANG model, the
YANG model defined in this document is interface independent. The
model is included in [I-D.ietf-teas-actn-yang], which indicates the
typical usage of IETF YANG models in ACTN architecture specified by
[RFC8453]. More specifically, the usage of this model between
controllers is described in
[I-D.ietf-ccamp-transport-nbi-app-statement].
The YANG data model in this document conforms to the Network
Management Datastore Architecture defined in [RFC8342].
1.1. Terminology and Notations

* state data
The terminology for describing YANG data models is found in
[RFC7950].
1.2. Tree Diagram
A simplified graphical representation of the data model is used in
Section 3 of this document. The meaning of the symbols in these
diagrams is defined in [RFC8340].
1.3. Prefix in Data Node Names
In this document, the names of data nodes and other data model
objects are prefixed using the standard prefix associated with the
corresponding YANG imported modules, as shown in Table 1.

2. YANG Data Model for OTN Topology
2.1. OTN Topology Data Model Overview
This document aims to describe the data model for OTN topology. As a
classic Traffic-engineering (TE) technology, OTN provides TDM
switching in transport network [ITU-T_G.709]. Therefore, the YANG
module presented in this document augments from a more generic
Traffic Engineered (TE) network topology data model, i.e., the ietf-
te-topology, as specified in [RFC8795]. In section 6 of [RFC8795],
the guideline for augmenting TE topology model was provided, and in
this draft, we augment the TE topology model to describe the topology
in OTN network. Common types, identities and groupings defined in
[I-D.ietf-ccamp-layer1-types] is reused in this document. [RFC8345]
describes a network topology model and provides the fundamental model
for [RFC8795]. However, this work is not directly augmenting
[RFC8345]. Figure 1 shows the augmentation relationship.

Figure 1 - Relationship between OTN and TE topology models
The entities and TE attributes, such as node, termination points and
links, are still applicable for describing an OTN topology and the
model presented in this document only specifies technology-specific
attributes/information. The OTN-specific attributes in [RFC7139],
including the TPN, TS and TSG, can be used to represent the bandwidth
and label information. These attributes have been specified in
[I-D.ietf-ccamp-layer1-types], and used in this document for
augmentation of the generic TE topology model.
2.2. Attributes Augmentation
There are a few characteristics augmenting to the generic TE
topology.
Zheng, et al. Expires 8 January 2024 [Page 5]
Internet-Draft OTN Topology YANG Model July 2023
Following the guidelines described in [RFC8795], an otn-topology
network-type is specified as the indicator of OTN in the topology.
augment /nw:networks/nw:network/nw:network-types/tet:te-topology:
+--rw otn-topology!
Two OTN technology-specific parameters are specified to augment the
generic TE link attributes.
augment /nw:networks/nw:network/nt:link/tet:te
/tet:te-link-attributes:
+--rw tsg? identityref
+--rw distance? uint32
In OTN the resources is measured by the tributary slots (TS), as
specified in [RFC7139]. The tributary slot granularity (TSG)
attribute defines the granularity, such as 1.25G, 2.5G and 5G, used
by the TSs of a given OTN link. The distance attribute describes the
geographical distance between a pair of OTN link termination points.
This is usually measured by the length of the fibre.
The OTN topology model also allows reporting of the access links that
support the transparent client signals, defined in
[I-D.ietf-ccamp-layer1-types]. These links can also be multi-
function access links that can support one or more transparent client
signals and OTN.
A client-svc presence container is specified to augment the generic
TE link termination point to describe if the point is capable of
carrying a client signal and what kind of signal can be carried as
follow. The same presence container is also specified for the TE
link.
augment /nw:networks/nw:network/nw:node/nt:termination-point
/tet:te:
+--rw client-svc!
+--rw supported-client-signal* identityref
The list of support-client-signal is used to provide the capabilities
of the client signal specified in [I-D.ietf-ccamp-layer1-types].

Internet-Draft OTN Topology YANG Model July 2023
2.3. Bandwidth Augmentation
Following the guidelines in [RFC8795], the model augments all the
occurrences of the te-bandwidth container with the OTN technology-
specific attributes using the otn-link-bandwidth and otn-path-
bandwidth groupings defined in [I-D.ietf-ccamp-layer1-types].
2.4. Label Augmentation
The model augments all the occurrences of the label-restriction list
with OTN technology specific attributes using the otn-label-range-
info grouping defined in [I-D.ietf-ccamp-layer1-types].
Moreover, following the guidelines in [RFC8795], the model augments
all the occurrences of the te-label container with the OTN technology
specific attributes using the otn-label-start-end, otn-label-hop and
otn-label-step groupings defined in [I-D.ietf-ccamp-layer1-types].

5. IANA Considerations
It is proposed to IANA to assign new URIs from the "IETF XML
Registry" [RFC3688] as follows:
URI: urn:ietf:params:xml:ns:yang:ietf-otn-topology
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
This document registers a YANG module in the YANG Module Names
registry [RFC7950].
name: ietf-otn-topology
namespace: urn:ietf:params:xml:ns:yang:ietf-otn-topology
prefix: otnt
reference: RFC XXXX
RFC Editor Note: Please replace XXXX with the number assigned to the
RFC once this draft becomes an RFC.

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. Considerations in Section 8 of
[RFC8795]are also applicable to their subtrees in the module defined
in this document.
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. Considerations in Section 8 of
[RFC8795]are also applicable to their subtrees in the module defined
in this document.
