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). An Ethernet network can be either a client-layer network of an underlay transport network or a transport network itself. This document describes a YANG data model for Ethernet networks when used as a client-layer network of an underlay transport network (e.g., an Optical Transport Network (OTN)) or as a transport network technology. Yu, et al. Expires 17 April 2025 [Page 2] Internet-Draft ETH Topology Transport YANG Model October 2024 The YANG model defined in this document augments from the TE topology YANG model defined in [RFC8795], and imports from the generic Ethernet types defined in [I-D.ietf-ccamp-client-signal-yang]. The YANG data model in this document conforms to the Network Management Datastore Architecture defined in [RFC8342]. 1.1. Terminology and Notations The following terms are defined in [RFC7950] and are not redefined here: * client * server * augment * data model * data node The following terms are defined in [RFC6241] and are not redefined here: * configuration data * 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. 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 Table 1. Yu, et al.

Ethernet Topology Model Overview This document aims to describe the data model for Ethernet topology. As a classic Traffic-engineering (TE) technology, Ethernet can provide packet switching in transport network [ITU_G.8021]. 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 Ethernet network. Common types, identities and groupings defined in [I-D.ietf-ccamp-client-signal-yang] 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.

Attributes Augmentation Given the guidance for augmentation in [RFC8795], the following technology-specific augmentations need to be provided: * A network-type to indicate that the TE topology is an Ethernet Topology, as follow: augment /nw:networks/nw:network/nw:network-types/tet:te-topology: +--rw eth-tran-topology! * TE Bandwidth Augmentations as described in Section 2.2. * TE Label Augmentations as described in Section 2.3. 2.2. TE Bandwidth Augmentations Following the guidelines in [RFC8795], the model augments all the occurrences of the te-bandwidth container with the Ethernet technology specific attributes using the eth-bandwidth grouping defined in [I-D.ietf-ccamp-client-signal-yang]. 2.3. TE Label Augmentations The model augments all the occurrences of the label-restriction list with Ethernet technology specific attributes using the eth-label- restriction grouping defined in [I-D.ietf-ccamp-client-signal-yang]. Yu, et al. Expires 17 April 2025 [Page 5] Internet-Draft ETH Topology Transport YANG Model October 2024 Moreover, following the guidelines in [RFC8795], the model augments all the occurrences of the te-label container with the Ethernet technology specific attributes using the eth-label and eth-label-step groupings defined in [I-D.ietf-ccamp-client-signal-yang]. 3.

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-eth-te-topology Registrant Contact: The IESG. XML: N/A, the requested URI is an XML namespace. Yu, et al. Expires 17 April 2025 [Page 68] Internet-Draft ETH Topology Transport YANG Model October 2024 This document registers following YANG modules in the YANG Module Names registry [RFC7950]. name: ietf-eth-te-topology namespace: urn:ietf:params:xml:ns:yang:ietf-eth-te-topology prefix: etht reference: RFC XXXX RFC Editor: Please replace XXXX with the RFC number assigned to this document. 6. Manageability Considerations TBD. 7. Security Considerations The data following the model defined in this document is exchanged via, for example, the interface between an orchestrator and a transport network controller. The security concerns mentioned in [RFC8795] for using ietf-te-topology.yang model also applies to this document. The YANG module defined in this document can be accessed via the RESTCONF protocol defined in [RFC8040], or maybe via the NETCONF protocol [RFC6241]. There are a number of data nodes defined in the YANG module which 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., POST) to these data nodes without proper protection can have a negative effect on network operations. Editors note: to list specific subtrees and data nodes and their sensitivity/vulnerability. 8. References 8.1.
