A YANG Data Model for Optical Transport Network Topology
draft-ietf-ccamp-otn-topo-yang-11
Abstract
This document describes a YANG data model to describe the topologies
of an Optical Transport Network (OTN). It is independent of control
plane protocols and captures topological and resource related
information pertaining to OTN. This model enables clients, which
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 can be constructed of equipments utilizing any of a
number of different transport technologies such as the Optical
Transport Networks (OTN) or packet transport such as provided by the
MPLS-Transport Profile (MPLS-TP).
This document defines a data model of an OTN network topology, using
YANG [RFC7950]. The model can be used by an application exposing to
a transport controller. Furthermore, it can be used by an
application for the following purposes (but not limited to):
Zheng, et al. Expires March 25, 2021 [Page 2]
Internet-Draft OTN Topology YANG Model September 2020
o To obtain a whole view of the network topology information of its
interest;
o To receive notifications with regard to the information change of
the OTN topology;
o To enforce the establishment and update of a network topology with
the characteristic 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 augmenting 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].
Other topology models for Optical network technologies, including
fixed Dense Wavelength Switched Optical Network (WSON) and flexible
optical networks (a.k.a., flexi-grid networks), are covered in
[I-D.ietf-ccamp-wson-yang] and [I-D.ietf-ccamp-flexigrid-yang],
respectively.
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 document 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 Some of the key terms used in this document are listed as follow.
o TS: Tributary Slot.
o TSG: Tributary Slot Granularity.
o TPN: Tributary Port Number.
3. YANG Data Model for OTN Topology
3.1. OTN Topology Data Model Overview
This document aims to describe the data model for OTN topology. As a
classic Traffic-engineering (TE) technology, OTN provide TDM
switching in transport network [ITU-Tg709]. 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 respectively augment the OTN attributes, TE bandwidth
and TE label. Generic groupings defined in
[I-D.ietf-ccamp-layer1-types] is reused as well in this document.
[RFC8345] describes a network topology model and provide the
fundamental model for [RFC8795]. However, this work is not directly
augmenting [RFC8345].
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 with 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.
For different order of ODU in OTN technology, the te-bandwidth is
augmented to allow specifying the type of ODU container and the
number a link can support per priority level. For example, for a
ODU3 link, it may advertise 32*ODU0, 16*ODU1, 4*ODU2 available, or
multiple ODUflex, assuming only a single priority level is supported.
If one of ODU2 resource is taken to establish a ODU path, then the
availability of this ODU link is updated as 24*ODU0, 12*ODU1, 3*ODU2,
or multiple ODUflex available. If there are equipment hardware
limitations, then a subset of potential ODU type SHALL be advertised.
For instance, an ODU3 link may only support 4*ODU2.

Note the model in this document re-uses some typedefs, identities and
groupings defined in ietf-layer1-types, which is specified in
[I-D.ietf-ccamp-layer1-types].
The YANG module ietf-otn-topology defined in this document conforms
to the Network Management Datastore Architecture (NMDA) defined in
[RFC8342].

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: otntopo
reference: RFC XXXX
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
Zheng, et al. Expires March 25, 2021 [Page 67]
Internet-Draft OTN Topology YANG Model September 2020
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:
/nw:networks/nw:network/nw:network-types/tet:te-topology
/nw:networks/nw:network/nt:link/tet:te/tet:te-link-attributes
/nw:networks/nw:network/nw:node/nt:termination-point/tet:te
/nw:networks/nw:network/.../tet:te-bandwidth/tet:technology
/nw:networks/nw:network/nw:node/tet:te/.../tet:label-restriction
/nw:networks/nw:network/nw:node/.../tet:te-label/tet:technology
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: Currently there is no such data nodes, temporarily kept
for review.
