"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
Status of This Memo
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

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].

Internet-Draft draft-ietf-detnet-yang-08 October 2020
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. Terminologies
This documents uses the terminologies defined in [RFC8655].
3. DetNet Configuration Module
DetNet configuration module includes DetNet App-flow configuration,
DetNet Service Sub-layer configuration, and DetNet Forwarding Sub-
layer configuration. The corresponding attributes used in different
sub-layers are defined in Section 3.1, 3.2, 3.3 respectively.
3.1. DetNet Appliction Flow Configuration Attributes
DetNet application flow is responsible for mapping between
application flows and DetNet flows at the edge node(egress/ingress
node). Where 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 Configuration Attributes
DetNet service functions, e.g., DetNet tunnel initialization/
termination and service protection, are provided in DetNet service
sub-layer. To support these functions, the following service
attributes need to be configured:
o DetNet flow identification
o 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 Configuration 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
Geng, et al. Expires April 15, 2021 [Page 3]
Internet-Draft draft-ietf-detnet-yang-08 October 2020
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:
o Traffic Specification, refers to Section 7.2 of
[I-D.ietf-detnet-flow-information-model]. It may used for
resource reservation, flow shaping, filtering and policing.
o Explicit path, existing explicit route mechanisms can be reused.
For example, if Segment Routing (SR) tunnel is used as the
transport tunnel, the configuration is mainly at the ingress node
of the transport layer; if the static MPLS tunnel is used as the
transport tunnel, the configurations need to be at every transit
node along the path; for pure IP based transport tunnel, it's
similar to the static MPLS case.
4. DetNet Flow Aggregation
DetNet provides the capability of flow aggregation to improve
scaleability 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:
o Aggregation flow encapsulation/decapsulation/identification
o Mapping individual DetNet flows to an aggregated flow
o Changing traffic specification parameters for aggregated flow
The following cases of DetNet aggregation are supported:
o aggregate data flows into an application which is then mapped to a
service sub-layer at the ingress node. Note the data flows may be
other DetNet flows.
o map each DetNet application to a single service sub-layer and
allowing the aggregation of multiple applications at the ingress

Internet-Draft draft-ietf-detnet-yang-08 October 2020
node, and vice versa for de-aggregation. A classifier may be
required to de-aggregate the respective applications.
o map each DetNet application uniquely to a single service sub-layer
where those sub-layers may be encapsulated as a single service
sub-layer and hence aggregating the applications at the ingress
node, and vice versa for de-aggregation. In this case, the
service sub-layer identifier may be sufficient to identify the
application. A classifier may be required to de-aggregate the
service sub-layers.
o aggregate DetNet service sub-layers into an aggregated flow by
using the same forwarding sub-layer at ingress node or relay node,
and vice versa for de-aggregation.
o aggregate DetNet flows with different forwarding sub-layer into an
aggregated flow by using the same forwarding sub-layer at transit
node, and vice versa for de-aggregation.
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:
+-----------+
|ietf-detnet|
+-----+-----+
|
+-------------+---------------+
| | |
+-----+-----+ +-----+-----+ +-------+------+
| App Flows | |service s-l| |forwarding s-l|
+-----------+ +-----------+ +--------------+
There are three instances in DetNet YANG Model: App-flow instance,
service sub-layer instance and forwarding sub-layer instance,
respectively corresponding to four parts of DetNet functions defined
in section 3.
