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).
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.

Internet-Draft ETH Topology Transport YANG Model October 2023
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.

2. 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.

Figure 1: Relationship between Ethernet and TE topology models
The entities and TE attributes, such as node, termination points and
links, are still applicable for describing an Ethernet topology and
the model presented in this document only specifies technology-
specific attributes/information.
2.1. 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 11 April 2024 [Page 5]
Internet-Draft ETH Topology Transport YANG Model October 2023
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].

5. 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 11 April 2024 [Page 68]
Internet-Draft ETH Topology Transport YANG Model October 2023
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.
