There are three instances in DetNet YANG Model: App-flow instance, There are three instances in DetNet YANG Model: App-flow instance,
service sub-layer instance and forwarding sub-layer instance, service sub-layer instance and forwarding sub-layer instance,
respectively corresponding to four parts of DetNet functions defined respectively corresponding to four parts of DetNet functions defined
in section 3. In each instance, there are four elements: name, in- in section 3.
segments, out-segments and operations, which means:
o Name: indicates the key value of the instance identification.
o In-segments: indicates the key value of identification, e.g.,
Layer 2 App flow identification, Layer 3 App flow identification
and DetNet flow identification.
o Out-segments: indicates the information of DetNet processing(e.g.,
DetNet forwarding, DetNet header Encapsulation) and the mapping
relationship to the lower sub-layer/sub-network.
o Operations: indicates DetNet functions, e.g., DetNet forwarding
functions, DetNet Service functions, DetNet Resource Reservation.
These elements are different when the technologies used for the
specific instance is different. So this structure is abstract, which
allows for different technology specifics as defined in different
data plane drafts.

7. An alternative DetNet YANG model 7. Open Issues
This is a model that is organized by the concepts in the flow model.
In order to align with the principles in the flow document a ground
up model was built. In order to illustrate this YANG model some
example test configurations are used to validate the model. Building
the DetNet YANG model is not that easy because the number of
permutations of IP/MPLS data planes with and without aggregation at
each layer is hard to keep straight. This model tries to follow the
current DetNet data plane documents and supported data planes. The
examples do not illustrate aggregation but the models are build for
several levels of aggregation.
7.1. Conventions
This YANG model consists of three main sections: application, service
sub-layer and forwarding sub-layer, that use a number of common
building blocks. Many of the building blocks are also the same as
the first model presented in this document. To minimize duplication,
leaf-refs between the sections are utilized. With a single leaf-ref
between an application and a service sub-layer the backend code can
relate the two instances. The backend code can also populate a read
only instance of a leaf-ref for the operational view so leaf-refs
only need to be configured once for both objects. Early versions of
the model used leaf-refs configure mainly outside the service sub-
layer, however this turned out being awkward because the in the
current model of the service sub-layer presented here it is binding a
service id to the leaf-ref. Therefore the leaf-ref for an
application and a forwarding sub-layer is more naturally configured
from the service sub-layer.
Another point about the model is each component has two
unidirectional parts. Applications would typically contain both
directions and become a complete bidirectional entity containing both
directionsl of a flow. Service sub-layers components can be
configured as unidirectional with only one direction being
configured. Forwarding sub-layer components are unidirectional.
Leaf-refs are used for each direction even though there are cases
where a single leaf-ref could work in a bidirctional model. DetNet
Services require configuarion of each undirectional flow and have
configuration options based on the roles they play and the types of
traffic mappings.
DetNet Edges have application, service and forwarding configuration.
DetNet Relays only use DetNet services sub-layer and forwarding sub-
layer configuration. DetNet Transit nodes may only have forwarding
sub-layer configuration. The behavior is DetNet service dependent,
such that a a physical node may be an edge node for some flows, it
may be a relay node for some flows and it may be a transit node for
some flows. The full YANG model is defined and only the relevant
aspects are configured at each stage.
7.1.1. Aggregation
Aggregation may be configured at each of the instances. Aggregation
is data plane specific. DetNet Service Sub-layer MPLS aggregation
for example, from application to service adds a per Application
Service sub-layer label. If a DetNet service is aggregated to
another DetNet service there are a couple ways this can be
accomplished.
A service sub-layer can play a role similar to an application to
another service allowing aggregation of services. A service sub-
layer can appear as relay service peering with that service. Relay
functions are dependent in the traffic type. Aggregation can be
achieved by encapsulation (MPLS) or by wild cards (IP) using the
native IP header. IP headers that are used in place aggregate by
allowing a broader address range (wild cards) or port range or DSCP
filter. These aggregating flows also require the reverse operation
to disaggregate the traffic at the edge of the DetNet service.
There are many ways to achieve aggregation and this can complicate
the YANG design to some degree. The current models support
aggregation but the configuration examples provided are illustrating
no aggregation for this version of the draft.

7.4. Test Configuration
The following XML test configuration shows some of the parameters for
a DetNet application, service sub-layer and forwarding sub-layer.
7.4.1. DetNet Test Configuration YANG Model
The case illustrated is for an ingress IP application to an MPLS
service sub-layer and MPLS forwarding sub-layer. In this example a
unidirectional flow is configured. The application input traffic is
IP. The Service links the application "app1", the service ID, a
service label and the outgoing forwarding sublayer "fsl1". The
service label is from the remote end serice for the unidirectional
path.

7.4.2. DetNet Test Configuration YANG Model
The next case illustrated is for an egress IP application from an
MPLS service sub-layer and MPLS forwarding sub-layer. In this
example a unidirectional flow is configured. The application egress
traffic is IP. The Service links the application "app2", the service
ID, a service label and the outgoing forwarding sub-layer "fsl2".
Again the service label is relevant to this egress service. The
forwarding sub-layer has an mpls stack that it removes. The next
label can be looked up because the forwarding sub-layer has a
reference to any DetNet services and those services have registered
the service label such that forwarding layer can forward to the
respective service sub-layer. Since the service sub-layer label is
unique to "app1" the service layer can forward the flow to the
correct app1. While not illustrated a single service can associated
multiple applications with a unique service label.
