A transport network is a server-layer network to provide connectivity services to its client. In this draft the topology of Ethernet with TE is described with YANG data model.
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. The topology model in Traffic-Engineered network has been defined in both generic way and technology-specific way. The generic model, which is the base TE YANG model, can be found at . Technology-specific models, such as OTN/WSON topology model, have also been defined in and respectively. Corresponding topology on client-layer is also required, to have a complete topology view from the perspective of network controllers.
This document defines a data model of all client-layer Topology, using YANG language defined in . The model is augmenting the generic TE topology model, and can be used by either applications exposing to a network controller or among controllers. Furthermore, it can be used by an application for topology description in client-layer network.
A simplified graphical representation of the data model is used in this document. The meaning of the symbols in the YANG data tree presented later in this document is defined in . They are provided below for reference.
Brackets "[" and "]" enclose list keys.
Abbreviations before data node names: "rw" means configuration (read-write) and "ro" state data (read-only).
Symbols after data node names: "?" means an optional node, "!" means a presence container, and "*" denotes a list and leaf-list.
Parentheses enclose choice and case nodes, and case nodes are also marked with a colon (":").
Ellipsis ("...") stands for contents of subtrees that are not shown.

Editor Notes: This section is used to note temporary discussion/conclusion that to be fixed in the future version, and will be removed before publication.
201902: we have noticed that Ethernet is the only client signal (on the perspective of OTN) which need a topology. So it is possible that the title of this document will be changed to "A YANG Data Model for Ethernet Topology". The proposal of this work is that the document will follow up the progress of draft-zheng-ccamp-client-signal-yang, with draft-zheng-ccamp-client-tunnel-yang together. (solved in -06)
201902: will have to align with TE topology model, currently is a totally different format with necessary parameters, a big change is expected. (solved in -06.)
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 .
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.
We would like to thank Igor Bryskin and Daniel King for their comments and discussions.
