3.1. DetNet Application Flow YANG Attributes 3.1. DetNet Application Flow YANG Attributes
DetNet application flow is responsible for mapping between DetNet application flow is responsible for mapping between
application flows and DetNet flows at the edge node(egress/ingress application flows and DetNet flows at the edge node(egress/ingress

3.2. DetNet Service Sub-layer YANG Attributes 3.2. DetNet Service Sub-layer YANG Attributes
DetNet service functions, e.g., DetNet tunnel initialization/ DetNet service functions, e.g., DetNet tunnel initialization/
termination and service protection, are provided in the DetNet termination and service protection, are provided in the DetNet
service sub-layer. To support these functions, the following service service sub-layer. To support these functions, the following service
attributes need to be configured: attributes need to be configured:
o DetNet flow identification * DetNet flow identification
* Service function indication, indicates which service function will
o Service function indication, indicates which service function will
be invoked at a DetNet edge, relay node or end station. (DetNet be invoked at a DetNet edge, relay node or end station. (DetNet
tunnel initialization or termination are default functions in tunnel initialization or termination are default functions in
DetNet service layer, so there is no need for explicit DetNet service layer, so there is no need for explicit
indication). The corresponding arguments for service functions indication). The corresponding arguments for service functions

4. DetNet Flow Aggregation 4. DetNet Flow Aggregation
DetNet provides the capability of flow aggregation to improve DetNet provides the capability of flow aggregation to improve
scaleability of DetNet data, management and control planes. scalability of DetNet data, management and control planes.
Aggregated flows can be viewed by the some DetNet nodes as individual Aggregated flows can be viewed by the some DetNet nodes as individual
DetNet flows. When aggregating DetNet flows, the flows should be DetNet flows. When aggregating DetNet flows, the flows should be
compatible: if bandwidth reservations are used, the reservation compatible: if bandwidth reservations are used, the reservation
should be a reasonable representation of the individual reservations; should be a reasonable representation of the individual reservations;
if maximum delay bounds are used, the system should ensure that the if maximum delay bounds are used, the system should ensure that the
aggregate does not exceed the delay bounds of the individual flows. aggregate does not exceed the delay bounds of the individual flows.
The DetNet YANG model defined in this document supports DetNet flow The DetNet YANG model defined in this document supports DetNet flow
aggregation with the following functions: aggregation with the following functions:
o Aggregation flow encapsulation/decapsulation/identification * Aggregation flow encapsulation/decapsulation/identification
* Mapping individual DetNet flows to an aggregated flow
o Mapping individual DetNet flows to an aggregated flow
o Changing traffic specification parameters for aggregated flow * Changing traffic specification parameters for aggregated flow
The following cases of DetNet aggregation are supported: The following cases of DetNet aggregation are supported:
o Ingress node aggregates App flows into a service sub-layer of * Ingress node aggregates App flows into a service sub-layer of
DetNet flow DetNet flow
o In ingress node, the service sub-layers of DetNet flows are * In ingress node, the service sub-layers of DetNet flows are
aggregated into a forwarding sub-layer aggregated into a forwarding sub-layer
o In ingress node, the service sub-layers of DetNet flows are * In ingress node, the service sub-layers of DetNet flows are
aggregated into a service sub-layer of an aggregated DetNet flow aggregated into a service sub-layer of an aggregated DetNet flow
o Relay node aggregates the forwarding sub-layers DetNet flows into * Relay node aggregates the forwarding sub-layers DetNet flows into
a forwarding sub-layer a forwarding sub-layer
o Relay node aggregates the service sub-layers of DetNet flows into * Relay node aggregates the service sub-layers of DetNet flows into
a forwarding sub-layer a forwarding sub-layer
o Relay node aggregates the service sub-layers of DetNet flows into * Relay node aggregates the service sub-layers of DetNet flows into

o Transit node aggregates the forwarding sub-layers of DetNet flows * Transit node aggregates the forwarding sub-layers of DetNet flows
into a forwarding sub-layer into a forwarding sub-layer
Traffic requirements and traffic specification may be tracked for Traffic requirements and traffic specification may be tracked for
individual or aggregate flows but reserving resources and tracking individual or aggregate flows but reserving resources and tracking
the services in the aggregated flow is out of scope. the services in the aggregated flow is out of scope.

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.

Figure 16: Example C-3 DetNet JSON Relay Service Sub-Layer
Disaggregation
A.7. 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.

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.
