Internet-Draft | OTN Topology YANG Model | April 2024 |
Zheng, et al. | Expires 21 October 2024 | [Page] |
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.¶

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).¶
This document defines a data model of an OTN 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].¶
Some of the key terms used in this document are listed as follow.¶

The terminology for describing YANG data models is found in [RFC7950].¶
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].¶

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. 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.¶

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.¶
There are a few characteristics augmenting to the generic TE topology.¶
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!¶
Three 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 otn-link +--rw odtu-flex-type? l1-types:odtu-flex-type +--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 supported-client-signal is used to provide the capabilities of the client signal specified in [I-D.ietf-ccamp-layer1-types].¶
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].¶
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].¶

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.¶
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.¶
In this YANG module, numerous data nodes inherited from their previous attachment are designed to be writable, creatable, and deletable, as indicated by the "config true" setting. In certain network contexts, these nodes might be deemed sensitive and susceptible to security risks. Unauthorized or unprotected write operations, such as "edit-config", could adversely impact network functionality, which may require an accurate topology representation for correct function. The security implications discussed in Section 8 of [RFC8795] also extend to the hierarchies within this module that include these data nodes.¶
Additionally, some data nodes accessible for reading might be considered sensitive or prone to vulnerabilities as they expose network topology information, which may be confidential information for some operators. Therefore, it's critical to manage access to these readable nodes carefully (for instance, through "get", "get-config", or "notification" commands) to safeguard them.¶
