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 central frequencies, slot widths, and the concept of the "frequency slot". This technology increases both transport networkLopez de Vergara, et al.Expires January 13, 2022 [Page 2]
Internet-Draft Flexi-Grid YANG July 2021 scalability and flexibility, allowing the optimization of bandwidth usage. [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 and use of "media-channel" defined in [I-D.ietf-ccamp-layer0-types]. An application example inSection 4 is also provided 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]. 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 [RFC7698] 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 nodeLopez de Vergara, et al.Expires January 13, 2022 [Page 3]
Internet-Draft Flexi-Grid YANG July 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] | | flexgt | 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.Lopez de Vergara, et al.Expires January 13, 2022 [Page 4]

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.5. YANG Data Model for Flexi-Grid Topology5.1. Flexi-Grid Topology Data Model Overview This document aims to describe the data model for Flexi-Grid topology. As a classic Traffic-engineering (TE) technology, Flexi- Grid provide WDM switching in transport network. Therefore the YANGLopez de Vergara, et al.Expires January 13, 2022 [Page 5]
Internet-Draft Flexi-Grid YANG July 2021 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], following the guidelines provided insection 6 of [RFC8795]. Common types, identities and groupings defined in [I-D.ietf-ccamp-layer0-types] are reused in this document. The figure below shows the augmentation relationship between YANG models. +-------------------------+ TE generic | ietf-te-topology | +-------------------------+ ^ | | Augments | +------------+-------------+ Flexi-Grid | ietf-flexi-grid-topology | +--------------------------+ Figure 3: Relationship between Flexi-Grid and TE topology models The entities and TE attributes, such as node, termination points and links, are still applicable for describing an Flexi-Grid topology and the model presented in this document only specifies with technology- specific attributes/information. The Flexi-Grid specific attributes in [RFC7699], including the grid type, channel spacing, slot width granularity, n and m parameters, can be used to represent the label information. These attributes have been specified in [I-D.ietf-ccamp-layer0-types], and used in this document for augmentation of the generic TE topology model. The YANG module ietf-flexi-grid-topology defined in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342].5.2. Attributes Augmentation There are a few characteristics augmenting to the generic TE topology.Lopez de Vergara, et al.Expires January 13, 2022 [Page 6]
Internet-Draft Flexi-Grid YANG July 2021 Following the guidelines in [RFC8795], a flexi-grid-topology network- type is specified as the indicator of Flexi-Grid in the topology as follows. augment /nw:networks/nw:network/nw:network-types/tet:te-topology: +--rw flexi-grid-topology! Figure 4: Flexi-Grid Topology Augmentation A flexi-grid-node presence container is specified, augmenting the generic TE node attributes, to indicate that the TE node is a Flexi- Grid node augment /nw:networks/nw:network/nw:node/tet:te /tet:te-node-attributes: +--rw flexi-grid-node! Figure 5: Flex-Grid Node Augmentation It is assumed that all the Flexi-Grid nodes are reconfigurable.5.3. Bandwidth Augmentation As described inSection 4.2 of [RFC7699], there is some overlap between bandwidth and label in layer0. The flexi-grid label resource information described insection 5.4, is sufficient to describe also the spectrum resources within a flexi- grid network. Therefore, the model does not define any augmentation for the te-bandwidth containers defined in [RFC8795].5.4. Label Augmentation The model augments all the occurrences of the label-restriction list with flexi-grid technology specific attributes using the flexi-grid- label-range-info grouping defined in [I-D.ietf-ccamp-layer0-types]. The Flexi-Grid label resource information described insection 5.4, is sufficient to describe also the spectrum resources within a flexi- Grid network. Therefore, the YANG model does not define anyLopez de Vergara, et al.Expires January 13, 2022 [Page 7]

Moreover, following the guidelines in [RFC8795], the model augments all the occurrences of the te-label container with the flexi-Grid technology specific attributes using the flexi-grid-label-start-end, flexi-grid-label-hop and flexi-grid-label-step groupings defined in [I-D.ietf-ccamp-layer0-types].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 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.Lopez de Vergara, et al.Expires January 13, 2022 [Page 59]
Internet-Draft Flexi-Grid YANG July 2021 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) 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-restriction9.
