Introduction The flexible grid (flexi-grid) optical network technology defined by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) and documented in Recommendation G.694.1 [G.694.1] and G.872 [G.872] provides an enhanced Dense Wavelength Division Multiplexing (DWDM) grid by defining a set of nominal slot widths, channel spacings, and the concept of the "frequency slot". In such an environment, a data-plane connection is switched based on allocated, variable-sized frequency ranges within the optical spectrum, creating what is known as a flexible grid (flexi-grid). This technology increases both transport network scalability and flexibility, allowing the optimization of bandwidth usage. Lopez de Vergara, et al. Expires August 26, 2021 [Page 2] Internet-Draft Flexi-Grid YANG February 2021 [RFC7698] provides a framework for GMPLS-Based control of flexi-grid DWDM networks while [RFC7699] defines generalized labels for the use of GMPLS in flexi-grid networks. This document presents a YANG data model [RFC7950] for flexi-grid objects in the dynamic optical network, including nodes, transponders and links, as well as how such links interconnect nodes. This document identifies the flexi-grid components, parameters and their values, characterizes the features and the performances of the flexi-grid elements.. For this, it augments [RFC8795], and imports the generic Layer 0 types defined in [I-D.ietf-ccamp-flexigrid-media-channel-yang]. An application example is provided towards the end of the document to better understand the utility of this YANG model. A partner document defines a second YANG module that described flexi- grid tunnels, i.e., the paths from source to destination through a number of intermediate nodes [I-D.ietf-ccamp-flexigrid-media-channel-yang]. Data types related to the optical layer are defined in [I-D.ietf-ccamp-layer0-types]. Impairment-aware traffic engineering topology is described in [I-D.ietf-ccamp-optical-impairment-topology-yang]. The YANG data model defined in this document conforms to the Network Management Datastore Architecture (NMDA) [RFC8342]. 2. Terminology Refer to [RFC7446] and [RFC7699] for the key terms used in this document. The following terms are defined in [RFC7950] and are not redefined here: o client o server o augment o data model o data node Lopez de Vergara, et al. Expires August 26, 2021 [Page 3] Internet-Draft Flexi-Grid YANG February 2021 The following terms are defined in [RFC6241] and are not redefined here: o configuration data o state data The terminology for describing YANG data models is found in [RFC7950]. 3. Tree Diagram A simplified graphical representation of the data model is used in this document. The meaning of the symbols in these diagrams is defined in [RFC8340]. 3.1. Prefixes in Data Node Names 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 Figure 1. It uses prefixes from [I-D.ietf-ccamp-layer0-types], [RFC8345], and [RFC8795]. +-------------+-------------------------+-----------------+ | Prefix | YANG module | Reference | +-------------+-------------------------+-----------------+ | l0-types | ietf-layer0-types | [RFCXXXX] | | tet-flexig | ietf-flexi-grid-topology| [RFCYYYY] | | nw | ietf-network | [RFC8345] | | nt | ietf-network-topology | [RFC8345] | | tet | ietf-te-topology | [RFC8795] | +-------------+-------------------------+-----------------+ Figure 1: Prefixes and Corresponding YANG modules RFC Editor Note: Please replace XXXX with the RFC numbers assigned to [I-D.ietf-ccamp-layer0-types]. Please replace YYYY with the RFC number assigned to this document. Please remove this note. 4. Example of Use In order to explain how this model is used, we provide the following example. An optical network usually has multiple transponders, switches (nodes) and links. Figure 1 shows a simple topology, where two physical paths interconnect two optical transponders.

We also provide nodes A and B identifiers, addresses and interfaces. o We do the same for the nodes B, C and D, providing their identifiers, addresses and interfaces, as well as the internal connectivity matrix between interfaces. o Then, we also define the links 1 to 5 that interconnect nodes, indicating which flexi-grid labels are available. o Other information, such as the slot frequency and granularity are also provided.

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 Transport Layer Security (TLS) [RFC8446]. The NETCONF access control model [RFC8341] provides the means to restrict access for particular NETCONF users to a preconfigured subset of all available NETCONF protocol operations and content. The NETCONF Protocol SSH [RFC6242] describes a method for invoking and running NETCONF within a SSH session as an SSH subsystem. The Network Configuration Access Control Model (NACM) [RFC8341] 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. A number of configuration data nodes defined in this document are writable/deletable (i.e., "config true"). These data nodes may be considered sensitive or vulnerable in some network environments. 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) Lopez de Vergara, et al. Expires August 26, 2021 [Page 57] Internet-Draft Flexi-Grid YANG February 2021 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/nw:node/tet:te/tet:te-node-attributes /te-connectivity-matrices/te-connectivity-matrix/tet:path- constraints/tet:te-bandwidth/tet:technology /nw:networks/nw:network/nw:node/tet:te /tet:tunnel-termination-point/tet:local-link-connectivities /tet:label-restrictions/tet:label-restriction 8. IANA Considerations IANA is requested to assigned a new URI from the "IETF XML Registry" [RFC3688] as follows: URI: urn:ietf:params:xml:ns:yang:ietf-flexi-grid-topology Registrant Contact: The IESG XML: N/A; the requested URI is an XML namespace. IANA is requested to assign a new YANG module name in the "YANG Module Names" registry [RFC6020] as follows: Name: ietf-flexi-grid-topology Namespace: urn:ietf:params:xml:ns:yang:ietf-flexi-grid-topology Prefix: flexi-grid-topology Reference: [This.I-D] 9.
