This document describes a YANG data model for Ethernet networks when used either as a client-layer network of an underlay transport network (e.g., an Optical Transport Network (OTN)) or as a transport network itself.
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.
The YANG model defined in this document augments from the TE topology YANG model defined in , and imports from the generic Ethernet types defined in .
The YANG data model in this document conforms to the Network Management Datastore Architecture defined in .

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 .
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 . In section 6 of ,
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
is reused in this document.
describes a network topology model and provides the fundamental model
for . However, this work is not directly augmenting
. shows the augmentation relationship.
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.
Attributes Augmentation
Given the guidance for augmentation in , the following
technology-specific augmentations need to be provided:
A network-type to indicate that the TE topology is an Ethernet
Topology, as follow:

TE Bandwidth Augmentations as described in .
TE Label Augmentations as described in .

TE Bandwidth Augmentations
Following the guidelines in , the model augments
all the occurrences of the te-bandwidth container with the Ethernet technology
specific attributes using the eth-bandwidth grouping defined in .
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 .
Moreover, following the guidelines in , 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 .

IANA Considerations
It is proposed that IANA should assign new URIs from the "IETF XML
Registry" as follows:
This document registers following YANG modules in the YANG Module
Names registry .
RFC Editor: Please replace XXXX with the RFC number assigned to this document.
Manageability Considerations
TBD.
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
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 , or maybe via the NETCONF
protocol .
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.

YANG Data Model for Traffic Engineering (TE) Topologies
This document defines a YANG data model for representing, retrieving, and manipulating Traffic Engineering (TE) Topologies. The model serves as a base model that other technology-specific TE topology models can augment.
A YANG Data Model for Transport Network Client Signals
Huawei Technologies
Futurewei
Huawei Technologies
Cisco
Huawei Technologies
A transport network is a server-layer network to provide connectivity
services to its client. The topology and tunnel information in the
transport layer has already been defined by generic Traffic-
engineered models and technology-specific models (e.g., OTN, WSON).
However, how the client signals are accessing to the network has not
been described. These information is necessary to both client and
provider.
This draft describes how the client signals are carried over
transport network and defines YANG data models which are required
during configuration procedure. More specifically, several client
signal (of transport network) models including ETH, STM-n, FC and so
on, are defined in this draft.
Network Management Datastore Architecture (NMDA)
Datastores are a fundamental concept binding the data models written in the YANG data modeling language to network management protocols such as the Network Configuration Protocol (NETCONF) and RESTCONF. This document defines an architectural framework for datastores based on the experience gained with the initial simpler model, addressing requirements that were not well supported in the initial model. This document updates RFC 7950.
The YANG 1.1 Data Modeling Language
YANG is a data modeling language used to model configuration data, state data, Remote Procedure Calls, and notifications for network management protocols. This document describes the syntax and semantics of version 1.1 of the YANG language. YANG version 1.1 is a maintenance release of the YANG language, addressing ambiguities and defects in the original specification. There are a small number of backward incompatibilities from YANG version 1. This document also specifies the YANG mappings to the Network Configuration Protocol (NETCONF).
Network Configuration Protocol (NETCONF)
The Network Configuration Protocol (NETCONF) defined in this document provides mechanisms to install, manipulate, and delete the configuration of network devices. It uses an Extensible Markup Language (XML)-based data encoding for the configuration data as well as the protocol messages. The NETCONF protocol operations are realized as remote procedure calls (RPCs). This document obsoletes RFC 4741. [STANDARDS-TRACK]
Common YANG Data Types
This document introduces a collection of common data types to be used with the YANG data modeling language. This document obsoletes RFC 6021.
A YANG Data Model for Network Topologies
This document defines an abstract (generic, or base) YANG data model for network/service topologies and inventories. The data model serves as a base model that is augmented with technology-specific details in other, more specific topology and inventory data models.
The IETF XML Registry
This document describes an IANA maintained registry for IETF standards which use Extensible Markup Language (XML) related items such as Namespaces, Document Type Declarations (DTDs), Schemas, and Resource Description Framework (RDF) Schemas.
RESTCONF Protocol
This document describes an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in the Network Configuration Protocol (NETCONF).
YANG Tree Diagrams
This document captures the current syntax used in YANG module tree diagrams. The purpose of this document is to provide a single location for this definition. This syntax may be updated from time to time based on the evolution of the YANG language.
