Introduction Internet-based traffic is dramatically increasing every year. Moreover, such traffic is also becoming more dynamic. Thus, transport networks need to evolve from current DWDM systems towards elastic optical networks, based on flexi-grid transmission and switching technologies [RFC7698]. This technology aims at increasing both transport network scalability and flexibility, allowing the optimization of bandwidth usage. Lopez de Vergara, et al. Expires September 25, 2019 [Page 2] Internet-Draft A YANG data model for Flexi-Grid March 2019 This document presents a YANG [RFC7950] model for flexi-grid objects in the dynamic optical network, including the nodes, transponders and links between them, as well as how such links interconnect nodes and transponders. The YANG model for flexi-grid networks allows the representation of the flexi-grid optical layer of a network, combined with the underlying physical layer. This document identifies the flexi-grid components, parameters and their values, characterizes the features and the performances of the flexi-grid elements. An application example is provided towards the end of the document to better understand their utility. 2. Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. In this document, these words will appear with that interpretation only when in ALL CAPS. Lower case uses of these words are not to be interpreted as carrying RFC-2119 significance. In this document, the characters ">>" preceding an indented line(s) indicates a compliance requirement statement using the key words listed above. This convention aids reviewers in quickly identifying or finding the explicit compliance requirements of this RFC. 3. Flexi-grid network topology model overview YANG is a data modeling language used to model configuration data manipulated by the NETCONF protocol. Several YANG models have already been specified for network configurations. For instance, the work in [RFC8345] has proposed a generic YANG model for network/service topologies and inventories. The work in [I-D.draft-ietf-teas-yang-te-topo] presents a data model to represent, retrieve and manipulate Traffic Engineering (TE) Topologies. These models serve as base models that other technology specific models can augment. A YANG model has also been proposed in [I-D.draft-dharini-ccamp-dwdm-if-yang] to manage single channel optical interface parameters of DWDM applications, and in Lopez de Vergara, et al. Expires September 25, 2019 [Page 3] Internet-Draft A YANG data model for Flexi-Grid March 2019 [I-D.draft-ietf-ccamp-wson-yang] another model has been specified for the routing and wavelength assignment TE topology in wavelength switched optical networks (WSONs). None of them are specific for flexi-grid technology. Then, as stated before, we propose a model to describe a flexi-grid topology that is split in two YANG sub-modules: o Flexi-grid-topology: In order to be compatible with existing proposals, we augment the definitions contained in [RFC8345] and [I-D.draft-ietf-teas-yang-te-topo], by defining the different elements we can find in a flexi-grid network: a node, a transponder and a link. For that, each of those elements is defined as a container that includes a group of attributes. References to the elements are provided to be later used in the definition of a media channel. It also includes the data types for the type of modulation, the flexi-grid technology, the FEC, etc. o Media-channel: This module defines the whole path from a source transponder to the destination through a number of intermediate nodes and links. For this, it takes the information defined before in the flexi-grid topology. This module is described in [I-D.draft-ietf-ccamp-flexigrid-media-channel-yang] The following section provides a detailed view of the first module. 4. Main building blocks of the Flexi-grid topology This section details the defined YANG module. It is listed below in section 6. The description of the three main components, flexi-grid-node, flexi-grid-transponder and flexi-grid-link is provided below. flexi-grid-sliceable-transponders are also defined. <flexi-grid-node> ::= <config> <state> <flexi-grid-node>: This element designates a node in the network. <config> ::= <flexi-grid-node-attributes-config> <config>: Contains the configuration of a node. <flexi-grid-node-attributes-config> ::= <list-interface> <connectivity_matrix> <flexi-grid-node-attributes-config>: Contains all the attributes related to the node configuration, such as its interfaces or its management addresses.

Formal Syntax The previous syntax specification uses the augmented Backus-Naur Form (BNF) as described in [RFC5234]. Lopez de Vergara, et al. Expires September 25, 2019 [Page 7] Internet-Draft A YANG data model for Flexi-Grid March 2019 5. 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 between them. Figure 1 shows a simple topology, where two physical paths interconnect two optical transponders. Media channel <==================================================> Path x <--------------------------------------------------> +----------+ +----------+ Link 1 |Flexi-grid| Link 2 |Flexi-grid| Link 3 .--->| node |<-------->| node |<---. | | B | | C | | | +----------+ +----------+ | v v /-----------\ /-----------\ / Flexi-grid \ / Flexi-grid \ | transponder | | transponder | \ A / \ E / \-----------/ \-----------/ ^ ^ | +----------+ | | Link 4 |Flexi-grid| Link 5 | '------------>| node |<-----------' | D | +----------+ <--------------------------------------------------> Path y Figure 1. Topology example. In order to configure a media channel to interconnect transponders A and E, first of all we have to populate the flexi-grid TED YANG model with all elements in the network: 1. We define the transponders A and E, including their FEC type, if enabled, and modulation type. We also provide node identifiers and addresses for the transponders, as well as interfaces included in the transponders. Sliceable transponders can also be defined if needed. 2. 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. 3. Then, we also define the links 1 to 5 that interconnect nodes and transponders, indicating which flexi-grid labels are available. Other information, such as the slot frequency and granularity are also provided. Lopez de Vergara, et al. Expires September 25, 2019 [Page 8] Internet-Draft A YANG data model for Flexi-Grid March 2019 Next, we can configure the media channel from the information we have stored in the flexi-grid TED, by querying which elements are available, and planning the resources that have to be provided on each situation. Note that every element in the flexi-grid TED has a reference, and this is the way in which they are called in the media channel. We refer to [I-D.draft-ietf-ccamp-flexigrid-media-channel-yang] to complete this example. 6. Flexi-grid TED YANG Model 6.1.

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 [RFC8446]. Lopez de Vergara, et al. Expires September 25, 2019 [Page 69] Internet-Draft A YANG data model for Flexi-Grid March 2019 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 over Secure Shell (SSH) [RFC6242] describes a method for invoking and running NETCONF within a Secure Shell (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) 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 The namespace used in the defined model has to register a URI in the IETF XML registry [RFC3688], as well as in the YANG Module Names registry [RFC6020]. Lopez de Vergara, et al.
