OTN transport networks, specified in [ITU-T_G.709], 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 generic TE Tunnel model specified in [I-D.ietf-teas-yang-te].¶
The YANG module ietf-otn-tunnel defined in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342].¶
Refer to [I-D.ietf-ccamp-otn-topo-yang] for the OTN specific terms terms used in this document.¶
The following terms are defined in [RFC7950] and are not redefined here:¶
The following terms are defined in [RFC6241] and are not redefined here:¶
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 this document. The meaning of the symbols in these diagrams is defined in [RFC8340].¶
In this document, 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 the following table.¶
| Prefix | YANG module | Reference |
|---|---|---|
| l1-types | ietf-layer1-types | [RFC YYYY] |
| otn-tnl | ietf-otn-tunnel | RFC XXXX |
| te | ietf-te | [RFC ZZZZ] |
RFC Editor Note: Please replace XXXX with the number assigned to the RFC once this draft becomes an RFC. Please replace YYYY with the RFC numbers assigned to [I-D.ietf-ccamp-layer1-types]. Please replace ZZZZ with the RFC numbers assigned to [I-D.ietf-teas-yang-te].¶
This document aims to describe the data model for OTN tunnel. The OTN tunnel model is using TE tunnel [I-D.ietf-teas-yang-te] as a basic model and augments it with OTN-specific parameters, including the bandwidth information and label information. Figure 1 shows the augmentation relationship.¶

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 in [RFC7139], including the Tributary Slot (TS) and Tributary Port Number (TPN), 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 tunnel model.¶
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 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, 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].¶

<CODE ENDS>
IANA is requested to register the following URI in the "ns" subregistry within the "IETF XML Registry" [RFC3688]:¶
URI: urn:ietf:params:xml:ns:yang:ietf-otn-tunnel
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
¶
IANA is requested to register the following YANG module in the "YANG Module Names" subregistry [RFC6020] within the "YANG Parameters" registry.¶
name: ietf-otn-tunnel
namespace: urn:ietf:params:xml:ns:yang:ietf-otn-tunnel
prefix: otn-tnl
reference: RFC XXXX
¶
RFC Editor Note: Please replace XXXX with the number assigned to the RFC once this draft becomes an RFC.¶
This section is modeled after the template described in Section 3.7 of [I-D.ietf-netmod-rfc8407bis].¶
The "ietf-te-types" and the "ietf-te-packet-types" YANG modules define data models that are designed to be accessed via YANG-based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. These protocols have to use a secure transport layer (e.g., SSH [RFC4252], TLS [RFC8446], and QUIC [RFC9000]) and have to use mutual authentication.¶
The Network Configuration Access Control Model (NACM) [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 can 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. Specifically, the following subtrees and data nodes have particular sensitivities/vulnerabilities:¶
"otnt:otn-bandwidth"¶
This subtree specifies the configurations of OTN technology-specific information under any occurrence of the tet:te-bandwidth container, as defined in [I-D.ietf-teas-yang-te] (e.g., "/te:te/te:tunnels/te:tunnel/te:te-bandwidth/te:technology/otnt:otn/otnt:otn-bandwidth"). By configuring the OTN bandwidth attributes, an attacker may create an unauthorized OTN traffic path. By removing or modifying it, a malicious attacker may cause OTN traffic to be disabled or misrouted.¶
"otnt:otn-label-range"¶
This subtree specifies the configurations of OTN technology-specific label range information under any occurrence of the tet:label-restriction container, as defined in [I-D.ietf-teas-yang-te] (e.g., "/te:te/te:tunnels/te:tunnel/te:primary-paths/te:primary-path/te:path-in-segment/te:label-restrictions/te:label-restriction/otnt:otn-label-range"). By configuring the OTN label range attributes, an attacker may create an unauthorized OTN traffic path. By removing or modifying, a malicious attacker may cause OTN traffic to be disabled or misrouted.¶
"otnt:otn-label"¶
This subtree specifies the configurations of OTN technology-specific label information under any occurrence of the tet:te-label container, as defined in [I-D.ietf-teas-yang-te] (e.g., "/te:te/te:tunnels/te:tunnel/te:primary-paths/te:primary-path/te:explicit-route-objects/te:route-object-include-exclude/te:type/te:label/te:label-hop/te:te-label/te:technology/otnt:otn/otnt:otn-label"). By configuring, removing or modifying the OTN label attributes, a malicious attacker may cause OTN traffic to be disabled or misrouted.¶
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. Specifically, the following subtrees and data nodes have particular sensitivities/vulnerabilities:¶
"otnt:otn-bandwidth"¶
This subtree specifies the configurations of OTN technology-specific information under any occurrence of the tet:te-bandwidth container, as defined in [I-D.ietf-teas-yang-te] (e.g., "/te:te/te:tunnels/te:tunnel/te:te-bandwidth/te:technology/otnt:otn/otnt:otn-bandwidth"). Unauthorized access to this data node can disclose the OTN bandwidth information of OTN tunnels and LSPs.¶
"otnt:otn-label-range"¶
This subtree specifies the configurations of OTN technology-specific label range information under any occurrence of the tet:label-restriction container, as defined in [I-D.ietf-teas-yang-te] (e.g., "/te:te/te:tunnels/te:tunnel/te:primary-paths/te:primary-path/te:path-in-segment/te:label-restrictions/te:label-restriction/otnt:otn-label-range"). Unauthorized access to this data node can disclose the state information of OTN tunnels and LSPs.¶
"otnt:otn-label"¶
This subtree specifies the configurations of OTN technology-specific label information under any occurrence of the tet:te-label container, as defined in [I-D.ietf-teas-yang-te] (e.g., "/te:te/te:tunnels/te:tunnel/te:primary-paths/te:primary-path/te:explicit-route-objects/te:route-object-include-exclude/te:type/te:label/te:label-hop/te:te-label/te:technology/otnt:otn/otnt:otn-label"). Unauthorized access to this data node can disclose the state information of OTN tunnels and LSPs.¶
This YANG module does not define RPC operations.¶
This YANG module uses groupings from other YANG modules that define nodes that may be considered sensitive or vulnerable in network environments. Refer to the Security Considerations of [I-D.ietf-ccamp-layer1-types] for information as to which nodes may be considered sensitive or vulnerable in network environments.¶
Finally, the YANG module described in this document augments the "ietf-te" YANG module [I-D.ietf-teas-yang-te] by adding data nodes. The security considerations for the subtrees described in those RFCs apply equally to the new data nodes that this module adds.¶
We would like to thank Yu Chaode for his comments and discussions.¶
