Introduction Transport networks have evolved from traditional Wavelength Switched Optical Networks (WSON) systems [RFC6163] based on only fixed-grid wavelength switching, towards elastic optical networks, based on flexi-grid Dense Wavelength Division Multiplexing (DWDM) transmission and switching technologies [RFC7698]. Such technology aims at increasing transport network scalability and flexibility, allowing bandwidth usage optimization. While [RFC9094] [I-D.ietf-ccamp-flexigrid-yang] focus on flexi-grid objects such as nodes, transponders and links, this document presents a YANG [RFC7950] model for the provisioning and management of Traffic Engineering (TE) tunnels and Label Switched Paths (LSPs) in DWDM Optical Networks, which can be Wavelength Switched Optical Networks (WSON) networks or Flexi-Grid Dense Wavelength Division Multiplexing (DWDM) Networks, or a mix of these two networks. This YANG module defines the path from a source transponder or node to the destination through several intermediate nodes in such a WDM optical network. Guo, et al. Expires 2 September 2024 [Page 2] Internet-Draft WDM Tunnel YANG Model March 2024 This document identifies the WDM tunnel components, parameters and their values, and characterizes the features and the performances of the WDM elements. An application example is provided towards the end of the document to understand their utility better. 2. Conventions and Definitions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. The terminology for describing YANG data models is found in [RFC7950]. 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: - client * server * augment * data model * data node The following terms are defined in [RFC6241] and are not redefined here: - configuration data * state data 3. Overview The generic TE tunnel attributes, such as source and destination node addresses, source and destination tunnel termination points (TTPs), are already defined by the base data model in [I-D.ietf-teas-yang-te]. The present model defines a WDM tunnel by augmenting the base model with the following WDM technology-specific constructs: * Global WDM layer constraints that influence the TE path selection, e.g., whether wavelength conversion or regeneration is considered Guo, et al. Expires 2 September 2024 [Page 3] Internet-Draft WDM Tunnel YANG Model March 2024 * Global transponder/transceiver configuration constraints, e.g., operational modes, tuning constraints of the transceiver * Global optical performance constraints, e.g. generalized Signal- to-noise (G-SNR) margin of a feasible optical path * Path-scope WDM layer constraints, e.g. identities of transceivers assigned to the primary or secondary path * List of links that defines the path * Other optical attributes Each path can be a segment path (only defined by the source and destination nodes or link termination points) or an end-to-end path (additionally needs source and destination transponders). Therefore, all the attributes are optional to support both situations. 4. Example of Use In order to explain how this model is used, the following example is provided. 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 via a combination of both WSON and Flexi-grid wavelength switched nodes and links. Guo, et al.

We also provide nodes A and E identifiers, addresses and interfaces. * 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. * Then, we also define the links 1 to 5 that interconnect nodes, indicating which WSON or flexi-grid labels are available. * Other information, such as the slot frequency and granularity are also provided. Guo, et al. Expires 2 September 2024 [Page 5] Internet-Draft WDM Tunnel YANG Model March 2024 After the nodes, links and transponders have been defined using [I-D.ietf-ccamp-flexigrid-yang] and [RFC9094] we can configure the tunnel 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, taking into account the global and path-specific WDM tunnel constraints. Note that every element in the flexi-grid topology has a reference, and this is the way in which they are called in the tunnel. * 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 tunnel, with source transponder A and source node B, and destination transponder E and destination node C. Thus, we are going to follow path x. * 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. * Finally, the flexi-grid topology has to be updated with each element usage status each time a tunnel 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: * /te:te/te:tunnels/te:tunnel * /te:te/.../te:te-bandwidth/te:technology * /te:te/.../te:type/te:label/te:label-hop/te:te-label/te:technology * /te:te/.../te:label-restrictions/te:label-restriction/te:label- start/te:te-label/te:technology * /te:te/.../te:label-restrictions/te:label-restriction/te:label- end/te:te-label/te:technology * /te:te/.../te:label-restrictions/te:label-restriction/ Editors note: we are using simplified description by folding similar branches to avoid repetition. 7.
