Introduction DetNet (Deterministic Networking) provides a capability to carry specified unicast or multicast data flows for real-time applications with extremely low packet loss rates and assured maximum end-to-end delivery latency. A description of the general background and concepts of DetNet can be found in [RFC8655]. This document defines a YANG model for DetNet based on YANG data types and modeling language defined in [RFC6991] and [RFC7950]. DetNet service, which is designed for describing the characteristics of services being provided for application flows over a network, and DetNet configuration, which is designed for DetNet flow path establishment, flow status reporting, and DetNet functions configuration in order to achieve end-to-end bounded latency and zero congestion loss, are both included in this document. 2. Terminology This document uses the terminology defined in [RFC8655]. 3. DetNet YANG Module The DetNet YANG module includes DetNet App-flow, DetNet Service Sub- layer, and DetNet Forwarding Sub-layer configuration and operational objects. The corresponding attributes used in different sub-layers are defined in Section 3.1, 3.2, 3.3 respectively. 3.1. DetNet Application Flow YANG Attributes DetNet application flow is responsible for mapping between application flows and DetNet flows at the edge node(egress/ingress node). The application flows can be either layer 2 or layer 3 flows. To map a flow at the User Network Interface (UNI), the corresponding attributes are defined in [I-D.ietf-detnet-flow-information-model]. 3.2. DetNet Service Sub-layer YANG Attributes DetNet service functions, e.g., DetNet tunnel initialization/ termination and service protection, are provided in the DetNet service sub-layer. To support these functions, the following service attributes need to be configured: * DetNet flow identification Geng, et al. Expires 20 November 2021 [Page 3] Internet-Draft draft-ietf-detnet-yang-12 May 2021 * Service function indication, indicates which service function will be invoked at a DetNet edge, relay node or end station. (DetNet tunnel initialization or termination are default functions in DetNet service layer, so there is no need for explicit indication). The corresponding arguments for service functions also needs to be defined. 3.3. DetNet Forwarding Sub-layer YANG Attributes As defined in [RFC8655], DetNet forwarding sub-layer optionally provides congestion protection for DetNet flows over paths provided by the underlying network. Explicit route is another mechanism that is used by DetNet to avoid temporary interruptions caused by the convergence of routing or bridging protocols, and it is also implemented at the DetNet forwarding sub-layer. To support congestion protection and explicit route, the following transport layer related attributes are necessary: * Flow Specification and Traffic Requirements, refers to [I-D.ietf-detnet-flow-information-model]. These may used for resource reservation, flow shaping, filtering and policing by a control plane or other network management and control mechanisms. * Since this model programs the data plane existing explicit route mechanisms can be reused. If a static MPLS tunnel is used as the transport tunnel, the configuration need to be at every transit node along the path. For an IP based path, the static configuration is similar to the static MPLS case. This document provides data-plane configuration of IP addresses or MPLS labels but it does not provide control plane mapping or other aspects. 4. DetNet Flow Aggregation DetNet provides the capability of flow aggregation to improve scalability of DetNet data, management and control planes. Aggregated flows can be viewed by the some DetNet nodes as individual DetNet flows. When aggregating DetNet flows, the flows should be compatible: if bandwidth reservations are used, the reservation should be a reasonable representation of the individual reservations; if maximum delay bounds are used, the system should ensure that the aggregate does not exceed the delay bounds of the individual flows. The DetNet YANG model defined in this document supports DetNet flow aggregation with the following functions: * Aggregation flow encapsulation/decapsulation/identification Geng, et al. Expires 20 November 2021 [Page 4] Internet-Draft draft-ietf-detnet-yang-12 May 2021 * Mapping individual DetNet flows to an aggregated flow * Changing traffic specification parameters for aggregated flow The following cases of DetNet aggregation are supported: * Ingress node aggregates App flows into a service sub-layer of DetNet flow * In ingress node, the service sub-layers of DetNet flows are aggregated into a forwarding sub-layer * In ingress node, the service sub-layers of DetNet flows are aggregated into a service sub-layer of an aggregated DetNet flow * Relay node aggregates the forwarding sub-layers DetNet flows into a forwarding sub-layer * Relay node aggregates the service sub-layers of DetNet flows into a forwarding sub-layer * Relay node aggregates the service sub-layers of DetNet flows into a service sub-layer of Aggregated DetNet flow * Relay node aggregates the forwarding sub-layers of DetNet flow into a service sub-layer of Aggregated DetNet flow * Transit node aggregates the forwarding sub-layers of DetNet flows into a forwarding sub-layer Traffic requirements and traffic specification may be tracked for individual or aggregate flows but reserving resources and tracking the services in the aggregated flow is out of scope. 5.

Example C-4 JSON Relay Service Sub-Layer Aggregation/ Disaggregation This illustrates the Relay node 1 aggregating the forwarding sub- layers of DetNet flow 1 and 2 into a service sub-layer of Aggregated DetNet flow 1. This also illustrates the Relay node 2 disaggregating the service sub-layer of Aggregated DetNet flow 1 to forwarding sub- layers of DetNet flow 1 and 2. A diagram illustrating both aggregation and disaggregation is shown and then the corresponding JSON operational data follows.

Example D-1 JSON Transit Forwarding Sub-Layer Aggregation/ Disaggregation This illustrates the Transit node 1 aggregating the forwarding sub- layers of DetNet flow 1 and 2 into a forwarding sub-layer. This also illustrates a Transit node 4 disaggregating a forwarding sub-layer into DetNet flow 1 and 2 forwarding sub-layers.
