1. Introduction
DetNet (Deterministic Networking) provides a capability the ability 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 data model for DetNet based on YANG data
types and modeling language defined in [RFC6991] and [RFC7950].
This document also includes the following:
* The DetNet service, which is designed for describing to describe the
characteristics of services being provided for application flows
over a network, and network.
* DetNet configuration, which is designed for to provide DetNet flow
path establishment, flow status reporting, and configuration of
DetNet functions
configuration in order to achieve end-to-end bounded latency
and zero congestion loss, are both included in this document. loss.
This Yang YANG data model is scoped to the description of the aggregation/
disaggregation and data plane capabilities of the DetNet data planes
defined in the DetNet Architecture "Deterministic Networking Architecture" [RFC8655] and DetNet Framework
"Deterministic Networking (DetNet) Data Plane Framework" [RFC8938].
DetNet operates at the IP layer and delivers service over lower-layer
technologies such as MPLS and IEEE 802.1 Time-Sensitive Networking
(TSN).

A-label, S-label,
"A-Label", "S-Label", and F-label "F-Label" are used in this document as
defined in [RFC8964].
4. DetNet YANG Module
The DetNet YANG module (Section 8) includes DetNet App-flow, DetNet Service Sub-
layer,
service sub-layer, and DetNet Forwarding Sub-layer forwarding sub-layer configuration and
operational objects. The corresponding attributes used in different
sub-layers are defined in Section 4.1 , Section 4.2 , Section 4.3 Sections 4.1, 4.2, and 4.3, respectively.
Layers of the objects typically occur in the different data instances
forming the node types defined in [RFC8655]. Figure Table 1 illustrates the
relationship between data instance node types and the included
layers. Node types are logical roles per DetNet service: a device
along one DetNet
service can be may use a device of one node type, while another service may
use the same device with a different node type. This model is a controller based model
controller-based model, because a controller or operator configures
all of the devices to form a service.

Table 1: DetNet Layers and Node Types
All of the layers have ingress/incoming and egress/outgoing
operations, but any instance may be configured as only
unidirectional. Ingress unidirectional
only. "Ingress" refers to any DetNet layer where a DetNet context is
applied. Ingress allows functions such as switching,
aggregation aggregation,
and encapsulation. Likewise, egress "Egress" refers to any DetNet layer where a
DetNet context is removed. Egress allows functions such as
switching, disaggregation disaggregation, and decapsulation. This means that each
unidirectional flow identifier configuration is programmed starting
at the ingress and flow status is reported at the ingress on each
end. In the MPLS cases case of MPLS, once encapsulated, the IP 6-tuple, see
[RFC8938], 6-tuple
parameters (see [RFC8938]) may not be required to be programmed
again. In the IP case, case of IP, without encapsulation, various IP flow id
identification parameters must be configured along the flow path.
In the YANG data model defined in this document, the terms source "source"
and destination "destination" are used as flow
identifiers identifiers, whereas ingress "ingress" and egress
"egress" refer to a DetNet application direction from the application
edge. Ingress is to "Ingress" means "to the DetNet
application application", and egress is from "egress"
means "from the application. application". The terms incoming "incoming" and outgoing "outgoing"
generally represent the flow direction towards the remote
application. Outgoing "Outgoing" is viewed as going down the stack from
Application the
application to Service the service sub-layer to Forwarding sub-layer the forwarding sub-layer, and incoming
is
"incoming" indicates the reverse. Although, However, in examples (Appendix B)
where there is both aggregation and disaggregation outgoing take place, "outgoing"
relates to the aggregating output and
incoming "incoming" relates to the
disaggregating flows.
At the egress point, forwarding information is determined by the App-
flow type with all DetNet-related headers removed. The In the case of
IP, the forwarding information can specify an output port, port or set a next-hop-address in
next-hop address. In the case of IP, or MPLS, it can set an MPLS label in case of MPLS. label.
4.1. DetNet Application Flow YANG Attributes
DetNet application flow is flows are responsible for mapping between
application flows and DetNet flows at the edge node (egress/ingress
node). The application flows can be either layer Layer 2 or layer Layer 3 flows.
To map a flow at the User Network User-Network Interface (UNI), the corresponding
attributes are defined in [RFC9016]. [RFC9016] are used.
4.2. 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 identification.
* Service function indication, indicates type. Indicates which service function will be
invoked at a DetNet edge, relay node node, or end station. (DetNet
tunnel initialization or and termination are default functions in the
DetNet service layer, so there is no need for explicit
indication). to indicate them
explicitly.) The corresponding arguments for service functions
also need to be defined.
4.3. DetNet Forwarding Sub-layer YANG Attributes
As defined in [RFC8655], the DetNet forwarding sub-layer optionally
provides congestion protection for DetNet flows over paths provided
by the underlying network. Explicit route is routes provide another mechanism that
is
used by DetNet to avoid temporary interruptions caused by the
convergence of routing or bridging protocols, and it is protocols. Explicit routes are
also implemented at the DetNet forwarding sub-layer.
To support congestion protection and explicit route, routes, the following
transport layer related
transport-layer-related attributes are necessary:
* Flow Specification specification and Traffic Requirements, traffic requirements are as described in
the information model provided in [RFC9016]. These may be used
for resource reservation, flow shaping, filtering filtering, and policing by
a control plane or other network management and control
mechanisms.
* Since this model programs the data plane plane, existing explicit route
mechanisms can be reused. If a static MPLS tunnel is used as the
transport tunnel, the configuration needs 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 data plane configuration of IP addresses or MPLS labels labels,
but it does not provide control plane mapping or other aspects.
5. DetNet Flow Aggregation
DetNet provides the capability of ability to perform flow aggregation to improve
the scalability of DetNet data, management management, and control planes.
Aggregated flows can be viewed by 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 data model defined in this document supports DetNet
flow aggregation with the following functions:
* Aggregated flow encapsulation/decapsulation/identification encapsulation/decapsulation/identification.
* Mapping individual DetNet flows to an aggregated flow flow.
* Changing traffic specification parameters for aggregated flows flows.
The following cases of DetNet aggregation scenarios are supported:
* Ingress The ingress node aggregates App flows App-flows into a service sub-layer of
a DetNet flow flow.
* In the ingress node, the service sub-layers of DetNet flows are
aggregated into a forwarding sub-layer sub-layer.
* In the ingress node, the service sub-layers of DetNet flows are
aggregated into a service sub-layer of an aggregated DetNet flow flow.
* Relay The relay node aggregates the forwarding sub-layers of DetNet
flows into a forwarding sub-layer sub-layer.
* Relay The relay node aggregates the service sub-layers of DetNet flows
into a forwarding sub-layer sub-layer.
* Relay The relay node aggregates the service sub-layers of DetNet flows
into a service sub-layer of Aggregated an aggregated DetNet flow flow.
* Relay The relay node aggregates the forwarding sub-layers of DetNet flow
flows into a service sub-layer of Aggregated an aggregated DetNet flow flow.
* Transit The transit node aggregates the forwarding sub-layers of DetNet
flows into a forwarding sub-layer sub-layer.
Traffic requirements and the traffic specification may be tracked for
individual or aggregate flows flows, but reserving resources and tracking
the services in the aggregated flow is are out of scope.
6. DetNet YANG Structure Considerations
The picture
This diagram shows the general structure of the DetNet YANG Model: data

There are three layer types in the DetNet YANG Model: App-flow data model: the App-
flow data layer, the service sub-layer sub-layer, and the forwarding sub-layer.
Additionally, the
Traffic traffic parameters are captured in a Traffic traffic
profile that can be referenced by any of the layers.
Below is a summary YANG tree showing the major items. A The complete
YANG tree is provided in section Appendix A.
A traffic profile can be created for an application, a service sub-
layer
layer, or a forwarding sub-layer. A single profile may be shared by
multiple applications/sub-layer. applications/sub-layers. Each profile indicates the members
currently using that profile.
Depending on which DetNet layers and functions are required, some or
all of the components may be configured. Examples are shown provided in
Appendix B.

10. Security Considerations
Security considerations for DetNet are covered in the DetNet
Architecture "Deterministic
Networking Architecture" [RFC8655] and DetNet "Deterministic Networking
(DetNet) Security Considerations [RFC9055] . Considerations" [RFC9055].
The YANG modules module specified in this document define defines a schema for data
that is designed to be accessed via network management protocols, protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
[RFC8446].
The Network Configuration Access Control Model (NACM) [RFC8341]
provides the means to restrict access for particular NETCONF or
RESTCONF users to a preconfigured subset of all available NETCONF or
RESTCONF protocol operations and content.
There are a number of data nodes defined in the this YANG module that are
writable/creatable/deletable (i.e., config true, which is the
default). These data nodes may be considered sensitive or vulnerable
in some network environments. Write operations (e.g., edit-config)
to these data nodes without proper protection can have a negative
effect on network operations. These are the subtrees and data nodes
and their sensitivity/vulnerability:
Unauthorized write operations (e.g., edit-config) to any elements of
this module can break or incorrectly connect DetNet flows. Since
DetNet is a configured Data Plane, data plane, any changes that are not
coordinated with all devices along the path will
create result in a denial
of service. In addition, arbitrary write operations could also enable an
attacker to modify a network path to enable select traffic to avoid
inspection or treatment by security controls, controls or to route traffic in
such a way that it the traffic would be subject to inspect/ inspection/
modification by an adversary node.
Similarly,
Some of the readable data nodes in these this YANG modules module may be considered
sensitive or vulnerable in some network environments. It is thus
important to control read access (e.g., via get, get-config, or
notification) to these data nodes. These are the subtrees and data
node
nodes and their sensitivity/vulnerability:
/detnet/app-flows: This controls the application details details, so it
could be considered sensitive.
/detnet/traffic-profile/member-app-flow: This links traffic profiles
to applications, service sub-layers sub-layers, and/or and forwarding sub-layers sub-layers,
so this also could also be considered more sensitive.
/detnet/service/sub-layer/incoming/app-flow: This links applications
to services.
/detnet/service/sub-layer/outgoing/app-flow: This links applications
to services.
The above nodes can reveal identifiable characteristics of the
application flows.
/detnet/service/sub-layer: This defines the service and forwarding
operations.
/detnet/fowarding/sub-layer:
/detnet/forwarding/sub-layer: This defines the forwarding
operations.
The above nodes can reveal some aspects of the network topology in
the case of
there is unauthorized access to this configuration.

Appendix B. Examples
The following examples are provided.
This section provides several examples. These examples are were tested
with
Yanglint the "yanglint" program and use operational output to exercise
both config true "config true" and
config false "config false" objects. Note that IPv4 and
IPv6 addresses are
supported supported, but for clarity in the examples and diagrams clarity, IPv4 has been
used in most examples. is used, with the
exception of Example A-1 (Appendix B.1). The IP types are imported
from [RFC6991] and [RFC6991]; these types support both IPv4 and IPv6.
The following conventions are used in the diagrams.
* Replication In the diagrams found in the PDF and Elimination HTML copies of this document,
replication and elimination points are shown as an R in "R" and E "E" in
circles
circles, respectively.
* Packet Headers headers, including a DetNet aggregation label or A-label,
Service (A-Label),
service label or S-label (S-Label), and Forwarding forwarding label or F-label (F-Label), are
illustrated at each hop as defined in [RFC8964].
* Aggregation/Disaggregation Aggregation/disaggregation nodes are indicated by dashed line dashed-line
boxes.
* Since the model augments IETF interfaces, minimal interface YANG
data is provided to validate the interface data as well. This
shows up as a named value value, such as "eth0" etc. "eth0", that is referenced by
the configuration.
The following
Below are examples of aggregation and disaggregation at various
points in DetNet. Figures Where indicated, figures are provided in the PDF
and HTML
version copies of this document.
B.1. Example A-1 A-1: JSON Configuration/Operational
This example illustrates that multiple App flows App-flows with the same source, the
same
destination, and the same traffic specification are aggregated
in into a single
DetNet flow service sub-layer. Ingress node 1 aggregates
App flows App-flows 0
and 1 into a service sub-layer of DetNet flow 1. Two ways of illustrating to
illustrate this follow, then are provided in Figures 1 and 2; the JSON operational
data model [RFC8259] corresponding to the diagrams follows. This example uses IPv6 is then shown in
Figure 3. The address format. format used in this example is IPv6.

Figure 4: 3: Example A-1 A-1: DetNet configuration Configuration Application Aggregation
B.2. Example B-1 B-1: XML Config: Configuration - Aggregation using Using a Forwarding
Sub-layer
As illustrated in Figure 5 illustrates the 4, DetNet service sub-layer flows 1 and 2
are aggregated into a single forwarding sub-layer. For the same
destination
destination, multiple DetNet flows use a single forwarding path path, and
service protection is performed by the corresponding service sub-
layer of each flow. A diagram illustrating this case is shown and
then the The corresponding XML operational data for node Ingress 1
"Ingress 1" follows.
Please consult the PDF or HTML versions copy for the Case B-1 Diagram. diagram.
Figure 5: 4: Case B-1 B-1: Example Config: Configuration - Aggregation using Using a
Forwarding Sub-layer
Figure 6 5 contains the operational XML configuration for the ingress
aggregation node illustrated in Figure 5. 4. In this example app-0 example, "app-0"
and
app-1 "app-1" are in separate service sub-layers with MPLS labels labels, and
the aggregation happens at the forwarding sub-layer afl-1 afl-1, using MPLS
labels.

Aggregation
B.3. Example B-2 B-2: JSON Service Aggregation Configuration
As illustrated in Figure 7 illustrates 6, DetNet service sub-layer flows 1 and 2
are aggregated into a service sub-layer of an aggregated flow.
Multiple DetNet flows with the same requirements for the same
destination are aggregated into a single aggregated DetNet flow, and
service protection and resource allocation are performed by an
aggregated DetNet flow service sub-layer and forwarding sub-layer. A diagram
illustrating this case is shown and then the
The corresponding JSON operational data for node Ingress 1 "Ingress 1" follows.
Please consult the PDF or HTML versions copy for the Case B-2 Diagram. diagram.
Figure 7: 6: Case B-2 B-2: Example Service Aggregation
Figure 8 7 contains the operational JSON configuration for the ingress
aggregation node illustrated in Figure 7. 6. In this example, service
sub-layer ssl-1 for DetNet flow DN1 DN-1 and ssl-2 for DetNet flow DN2 DN-2
aggregate at service sub-layer Detet DetNet flow asl-1. In this example example,
an aggregation service sub-layer asl-1 sub-layer, asl-1, is created to aggregated
ssl-1 and ssl2 ssl2, and that label is encapsulated in a separate
forwarding sub-
layer afl-1 sub-layer, afl-1, with MPLS labels.

Figure 8: 7: Example B-2 B-2: DetNet Service Aggregation
B.4. Example C-1 C-1: JSON Relay Aggregation/Disaggregation Configuration
Figure 9 8 illustrates the DetNet relay node's forwarding sub-layer
flows 1 and 2 aggregated into a single forwarding sub-layer. Service
protection and resource allocation are performed by the corresponding
service sub-layer and forwarding sub-layer of each flow. A diagram
illustrating Figure 8
illustrates both aggregation and disaggregation is shown disaggregation, and then the
corresponding JSON operational data follows.
Please consult the PDF or HTML versions copy for the Case C-1 Diagram. diagram.

Figure 10 9 contains the operational JSON configuration for the ingress
aggregation node illustrated in Figure 9. 8. In this example, a relay
performing aggregation at the forwarding sub-layer is illustrated.
Two DetNet flows DN1 -- DN-1 and DN2 DN-2 -- are replicated at each service sub-
layer.
sub-layer. The two forwarding sub-layers for the upside path are
aggregated at the forwarding sub-layer with label 20000 20000, and the two
forwarding sub-layers for the downside path are aggregated at the
forwarding sub-layer with label 20001. Figure 11 10 contains the
operational JSON configuration for the egress disaggregation node
illustrated in Figure 9. 8.

Layer
layer
Figure 12 11 illustrates the DetNet relay node node's service sub-layer flows
1 and 2 aggregated into a single forwarding sub-layer. Service
protection is performed by the corresponding service sub-layer of
each flow flow, and resource allocation is performed by an aggregated
forwarding sub-layer for all aggregated flows. A diagram
illustrating Figure 11 illustrates
both aggregation and disaggregation is shown disaggregation, and then the corresponding JSON
operational data follows.
Please consult the PDF or HTML versions copy for the Case C-2 Diagram. diagram.
Figure 12: 11: Case C-2 C-2: Example Service Aggregation/Disaggregation
Figure 13 12 contains the operational JSON configuration for the ingress
aggregation node illustrated in Figure 12. 11. In this example, a relay
performing aggregation at the forwarding sub-layer is illustrated.
Two DetNet flows DN1 -- DN-1 and DN2 DN-2 -- are replicated at each service sub-
layer, and the
sub-layer. Each replicated each flow for the service sub-layer for the
upside path is aggregated at the single forwarding sub-layer with
MPLS label 20000, and the replicated each replicated flow for the service sub-layer
for the downside path is aggregated at the forwarding sub-layer with
MPLS label 20001. Figure 14 13 contains the operational JSON
configuration for the egress disaggregation node illustrated in
Figure 12. 11.

Disaggregation
Figure 15 14 illustrates the DetNet relay node node's service sub-layer flows
1 and 2 aggregated into a service sub-layer flow. Multiple DetNet
flows with the same requirements which that can use the same path are
aggregated into a single aggregated DetNet flow, and service
protection and resource allocation are performed by the service sub-
layer and forwarding sub-layer of the aggregated DetNet flow. A diagram
illustrating
Figure 14 illustrates both aggregation and disaggregation is shown disaggregation, and then the
corresponding JSON operational data follows.
Please consult the PDF or HTML versions copy for the Case C-3 Diagram. diagram.

Figure 16 15 contains the operational JSON configuration for the ingress
aggregation node illustrated in Figure 15. 14. In this example example, a relay
performing aggregation at the service sub-layer is illustrated. Two
DetNet flows DN1 -- DN-1 and DN2 DN-2 -- are relayed at each service sub-layer sub-
layer with MPLS labels 101 and 104 104, respectively, and each service
sub-layer is aggregated at a single service sub-layer flow and
replicated. Figure 17 16 contains the operational JSON configuration
for the egress disaggregation node illustrated in Figure 15. 14.

Figure 17: 16: Example C-3 C-3: DetNet Relay Service Sub-Layer Sub-layer Disaggregation
B.7. Example C-4 C-4: JSON Relay Service Sub-Layer Sub-layer Aggregation/
Disaggregation
Figure 18 17 illustrates the relay node DetNet relay node's forwarding sub-layer
flows 1 and 2 aggregated into a service sub-layer DetNet flow.
Multiple DetNet flows with the same requirements which that can use the
same path are aggregated into a single aggregated DetNet flow.
Service protection is performed by the service sub-layer of the
aggregated DetNet flow flow, and resource allocation is performed by the
forwarding sub-layer of each aggregated DetNet flow. A diagram
illustrating Figure 17
illustrates both aggregation and disaggregation is shown disaggregation, and then the
corresponding JSON operational data follows.
Please consult the PDF or HTML versions copy for the Case C-4 Diagram diagram.
Figure 18: 17: Case C-4 C-4: Example Service Aggregation/Disaggregation
Figure 19 18 contains the operational JSON configuration for the ingress
aggregation node illustrated in Figure 18. 17. In this example, a relay
performing aggregation at the service sub-layer is illustrated. Two
DetNet flows DN1 -- DN-1 and DN2 DN-2 -- are relayed at each service sub-layer. sub-
layer. The two DetNet forwarding sub-layer flows with MPLS labels
20004 and 20005 are aggregated at the single service sub-layer DetNet
flow and then replicated. Figure 20 19 contains the operational JSON
configuration for the egress disaggregation node illustrated in
Figure 18. 17.
