Introduction Transport networks are evolving from current DWDM systems towards elastic optical networks, based on flexi-grid transmission and switching technologies [RFC7698]. Such technology aims at increasing both transport network scalability and flexibility, allowing the optimization of bandwidth usage. While [I-D.ietf-ccamp-flexigrid-yang] focuses on flexi-grid objects such as nodes, transponders and links, this document presents a YANG [RFC7950] model for the flexi-grid media-channel. This YANG module defines the whole path from a source transponder or node to the destination through a number of intermediate nodes in the flexi-grid network. Lopez de Vergara, et al.Expires January 13, 2022 [Page 2] Internet-Draft Flexi-Grid YANG July 2021 This document identifies the flexi-grid media-channel 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. 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 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. Flexi-Grid Media-Channel Overview The present model defines a flexi-grid media-channel mainly composed of: o source address o source flexi-grid port o source flexi-grid transponder o destination address o destination flexi-grid port Lopez de Vergara, et al.Expires January 13, 2022 [Page 3] Internet-Draft Flexi-Grid YANG July 2021 o destination flexi-grid transponder o list of links that defines the path o other optical attributes Each path can be a media-channel (only defined by source and destination node) or a network media-channel (additionally needs source and destination transponders). Therefore, all the attributes are optional to support both situations. This is achieved by a combination of the traffic engineering tunnel attributes explained in [I-D.ietf-teas-yang-te] and augments when necessary. For instance, source address, source flexi-grid transponder, destination address and destination flexi-grid transponder attributes are directly taken from tunnel, whereas other attributes such as source flexi-grid port, destination flexi-grid port are defined, as they are specific for flexi-grid. 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. Lopez de Vergara, et al.Expires January 13, 2022 [Page 5] Internet-Draft Flexi-Grid YANG July 2021 After the nodes, links and transponders have been defined using [I-D.ietf-ccamp-flexigrid-yang] we can configure the media-channel from the information we have stored in the flexi-grid topology, 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 topology has a reference, and this is the way in which they are called in the media-channel. o Depending on the case, it is possible to define either the source and destination node ports, or the source and destination node and transponder. In our case, we would define a network media channel, with source transponder A and source node B, and destination transponder E and destination node C. Thus, we are going to follow path x. o Then, for each link in the path x, we indicate which channel we are going to use, providing information about the slots, and what nodes are connected. o Finally, the flexi-grid topology has to be updated with each element usage status each time a media channel is created or torn down. 5.

Security Considerations The configuration, state, and action data defined in this document are designed to be accessed via a management protocol with a secure transport layer, such as NETCONF [RFC6241] or RESTCONF [RFC8040]. 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. 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: o /te:te/te:tunnels/te:tunnel o /te:te/.../te:te-bandwidth/te:technology o /te:te/.../te:type/te:label/te:label-hop/te:te-label/te:technology o /te:te/.../te:label-restrictions/te:label-restriction/te:label- start/te:te-label/te:technology o /te:te/.../te:label-restrictions/te:label-restriction/te:label- end/te:te-label/te:technology o /te:te/.../te:label-restrictions/te:label-restriction/ Editors note: we are using simplified description by folding similar branches to avoid repetition. 7.
