| Internet-Draft | draft-ietf-detnet-yang-12 | May 2021 |
| Geng, et al. | Expires 20 November 2021 | [Page] |
This document contains the specification for the Deterministic Networking YANG Model for configuration and operational data for DetNet Flows. The model allows for provisioning of end-to-end DetNet service along the path without dependency on any signaling protocol. It also specifies operational status for flows.¶
The YANG module defined in this document conforms to the Network Management Datastore Architecture (NMDA).¶
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 RFC 2119 [RFC2119].¶
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.¶
Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.¶
Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."¶

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.¶
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.¶
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].¶
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:¶
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:¶
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:¶
The following cases of DetNet aggregation are supported:¶
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.¶
The picture shows that the general structure of the DetNet YANG Model:¶

Note to RFC Editor: this section may be removed on publication as an RFC.¶
<TBD>¶
The following examples are provided. These examples are tested with Yanglint and use operational output to exercise both config true and config false objects.¶
The following are examples of aggregation and disaggregation at various points in Detnet. Figures are provided in the PDF version of this document.¶
This illustrates simple aggregation. Ingress node 1 aggregates App flows 0 and 1 into a service sub-layer of DetNet flow 1. Two ways of illustrating this follow, then the JSON operational data model corresponding to the diagrams follows.¶

This illustrates the Relay node 1 aggregating the service sub-layers of DetNet flows 1 and 2 into a service sub-layer of Aggregated DetNet flow 1. It also illustrates the Relay node 2 disaggregating the aggregated DetNet flow 1 into the DetNet flows 1 and 2 service sub-layers. A diagram illustrating both aggregation and disaggregation is shown and then the corresponding JSON operational data follows.¶

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.¶
