1. 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. DetNet YANG Structure Considerations
The picture shows that the general structure of the DetNet YANG
Model:

Appendix A. Examples
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.
A.1. Example A-1 JSON Configuration/Operational
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.
Please consult the PDF or HTML versions for the Case A-1 Diagram.

A.2. Example B-1 XML Config: Aggregation using a Forwarding Sub-layer
This illustrates aggrgation in the service sub-layers of DetNet.
Flows 1 and 2 are aggregated into a forwarding sub-layer. A diagram
illustrating this case is shown and then the corresponding XML
operational data follows.
Please consult the PDF or HTML versions for the Case B-1 Diagram.

Figure 10: Example C-1 DetNet JSON Relay Service Disaggregation
A.5. Example C-2 JSON Relay Aggregation Service Sub-Layer
This illustrates the Relay node 1 aggregating the service sub-layers
of DetNet flows 1 and 2 into a forwarding sub-layer A diagram
illustrating both aggregation and disaggregation is shown and then
the corresponding JSON operational data follows.
Please consult the PDF or HTML versions for the Case C-2 Diagram.

Figure 13: Example C-2 DetNet JSON Relay Disaggregation Service
Sub-Layer
A.6. Example C-3 JSON Relay Service Sub-Layer Aggregation/
Disaggregation
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.
Please consult the PDF or HTML versions for the Case C-3 Diagram.

A.7. Example C-4 JSON Relay Service Sub-Layer Aggregation/

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.

Figure 19: Example C-4 DetNet JSON Relay Service Sub-Layer
Disaggregation
A.8. 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.
