Xu CAICT L. Wang China Mobile O. Gonzalez de Dios Telefonica July 31, 2018 A YANG Data Model for Optical Transport Network Topology draft-ietf-ccamp-otn-topo-yang-04 Abstract 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 can be constructed from equipments utilizing any of a number of different transport technologies such as the evolving Optical Transport Networks (OTN) or packet transport as provided by the MPLS-Transport Profile (MPLS-TP). This document describes a YANG data model to describe the topologies of an Optical Transport Network (OTN). It is independent of control plane protocols and captures topological and resource related information pertaining to OTN. This model enables clients, which interact with a transport domain controller via a REST interface, for OTN topology related operations such as obtaining the relevant topology resource information.

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 can be constructed of equipments utilizing any of a Zheng, et al. Expires February 1, 2019 [Page 2] Internet-Draft OTN Topology YANG Model July 2018 number of different transport technologies such as the Optical Transport Networks (OTN) or packet transport as provided by the MPLS- Transport Profile (MPLS-TP). This document defines a data model of an OTN network topology, using YANG [RFC7950]. The model can be used by an application exposing to a transport controller via a REST interface. Furthermore, it can be used by an application for the following purposes (but not limited to): o To obtain a whole view of the network topology information of its interest; o To receive notifications with regard to the information change of the OTN topology; o To enforce the establishment and update of a network topology with the characteristic specified in the data model, e.g., by a client controller; The YANG model defined in this document is independent of control plane protocols and captures topology related information pertaining to an Optical Transport Networks (OTN)-electrical layer, as the scope specified by [RFC7062] and [RFC7138]. Furthermore, it is not a stand-alone model, but augmenting from the TE topology YANG model defined in [I-D.ietf-teas-yang-te-topo]. Following TE topology YANG model, the YANG model defined in this document is interface independent. The applicability of models to interfaces is described in [I-D.ietf-teas-actn-yang]. Optical network technologies, including fixed Dense Wavelength Switched Optical Network (WSON) and flexible optical networks (a.k.a., flexi-grid networks), are covered in [I-D.ietf-ccamp-wson-yang] and [I-D.ietf-ccamp-flexigrid-yang], respectively. 2. Terminology and Notations 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 [I-D.ietf-netmod-yang-tree-diagrams]. They are provided below for reference. o Brackets "[" and "]" enclose list keys. o Abbreviations before data node names: "rw" means configuration (read-write) and "ro" state data (read-only). Zheng, et al. Expires February 1, 2019 [Page 3] Internet-Draft OTN Topology YANG Model July 2018 o Symbols after data node names: "?" means an optional node, "!" means a presence container, and "*" denotes a list and leaf-list. o Parentheses enclose choice and case nodes, and case nodes are also marked with a colon (":"). o Ellipsis ("...") stands for contents of subtrees that are not shown. o Some of the key terms used in this document are listed as follow. o TS: Tributary Slot. o TSG: Tributary Slot Granularity. o TPN: Tributary Port Number. 3. YANG Data Model for OTN Topology 3.1. OTN Topology Data Model Overview This document aims to describe the data model for OTN topology. As a classic Traffic-engineering (TE) technology, OTN provide TDM 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.yang, as specified in [I-D.ietf-teas-yang-te-topo]. In section 6 of [I-D.ietf-teas-yang-te-topo], the guideline for augmenting TE topology model was provided, and in this draft we respetively augment the OTN attributes, TE bandwidth and TE label. The entities and TE attributes, such as node, termination points and links, are still applicable for describing an OTN topology and the model presented in this document only specifies with technology- specific attributes/information. In OTN attributes augmentation, mainly OTN-specific parameters are included such as Tributary Slot Granularity (TSG), payload type and so on. For different order of ODU in OTN technology, the te-bandwidth is augmented to allow specifying the type of ODU container and the number a link can support per priority level. For example, for a ODU3 link, it may advertise 32*ODU0, 16*ODU1, 4*ODU2 available, assuming only a single priority level is supported. If one of ODU2 resource is taken to establish a ODU path, then the availability of this ODU link is updated as 24*ODU0, 12*ODU1, 3*ODU2 available. If there are equipment hardware limitations, then a subset of potential ODU type SHALL be advertised. For instance, an ODU3 link may only support 4*ODU2. Zheng, et al. Expires February 1, 2019 [Page 4] Internet-Draft OTN Topology YANG Model July 2018 The types of OTN label can be divided into the tributary ports and the tributary slots, represented by TPN or TS list respectively. In the TE-label augmentation, two optional label formats are available for label representation. Note the model in this document re-uses some attributes defined in ietf-otn-types.yang, which is specified in [I-D.ietf-ccamp-otn-tunnel-model]. The YANG module ietf-otn-topology defined in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342]. 3.2.

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-otn-topology Registrant Contact: The IESG XML: N/A; the requested URI is an XML namespace. This document registers a YANG module in the YANG Module Names registry [RFC7950]. name: ietf-otn-topology namespace: urn:ietf:params:xml:ns:yang:ietf- otn-topology prefix: otntopo reference: RFC XXXX 6. Security Considerations The YANG module specified in this document defines a schema for data that is designed to be accessed via network management protocols such as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS [RFC5246]. The NETCONF access control model [RFC6536] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content. There are a number of data nodes defined in this YANG module that 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., edit-config) to these data nodes without proper protection can have a negative effect on network operations. These are the subtrees and data nodes and their sensitivity/vulnerability: /nw:networks/nw:network/nw:network-types/tet:te-topology /nw:networks/nw:network/nt:link/tet:te/tet:te-link-attributes /nw:networks/nw:network/nw:node/nt:termination-point/tet:te /nw:networks/nw:network/.../tet:te-bandwidth/tet:technology /nw:networks/nw:network/nw:node/tet:te/.../tet:label-restriction /nw:networks/nw:network/nw:node/.../tet:te-label/tet:technology Zheng, et al. Expires February 1, 2019 [Page 54] Internet-Draft OTN Topology YANG Model July 2018 Editors note: we are using simplified description by folding similar branches to avoid repetation. Some of the readable data nodes in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control read access (e.g., via get, get-config, or notification) to these data nodes. These are the subtrees and data nodes and their sensitivity/vulnerability: Editors note: Currently there is no such data nodes, temporarily kept for review. 7.
