+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.

+

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].

+
+
+

+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!
+
+
+ +
+
+
+
+

+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].

+

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. Manageability Considerations +

+

TBD.

+
+
+
+
+

+6. 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.

+
+
+
+
+

+7. 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.
+
+
+

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.

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 [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. + + +============+=======================+===========+ + | Prefix | YANG module | Reference | + +============+=======================+===========+ + | yang | ietf-yang-types | [RFC6991] | + +------------+-----------------------+-----------+ + | etht-types | ietf-eth-tran-types | [RFCYYYY] | + +------------+-----------------------+-----------+ + | nw | ietf-network | [RFC8345] | + +------------+-----------------------+-----------+ + | nt | ietf-network-topology | [RFC8345] | + +------------+-----------------------+-----------+ + | tet | ietf-te-topology | [RFC8795] | + +------------+-----------------------+-----------+ + | etht | ietf-eth-te-topology | RFCXXXX | + +------------+-----------------------+-----------+ + + Table 1: Prefixes and corresponding YANG modules + + RFC Editor Note: Please replace YYYY and XXXX with the number + assigned to the RFC once this draft becomes an RFC. + +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. + + +-------------------------+ + TE generic | ietf-te-topology | + +------------+------------+ + ^ + | + | Augments + | + +------------+------------+ + Ethernet | ietf-eth-te-topology | + +-------------------------+ + + 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]. + + 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.

Manageability Considerations + + TBD. + +6. 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. + +7. 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. + + 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. + +8.
