1. Introduction
Deterministic Networking (DetNet) is a service that can be offered by
a network to DetNet flows. As defined in [RFC8655], DetNet flows
provide deterministic services with guaranteed performance such as
end-to-end delay and low packet loss rate for unicast or multicast
data streams. The adequate network resource allocation and
reservation are required for DetNet flows. DetNet assumes that
DetNet control plane using traditional technologies such as RSVP-TE,
SR to achieve bandwidth and buffer resources allocation at each
DetNet node along the path of DetNet flows. The DetNet data plane
according to the existing DetNet mechanism makes best effort to
forward data packets with no network resource reservation and
occupation guarantee.
[I-D.ietf-teas-ietf-network-slices] provides the definition of
network slice in the context of IETF network and discusses the main
characteristics, necessary components and interfaces for the general
framework of IETF Network Slice. An IETF Network Slice delivers a
service to a customer by meeting connectivity resource requirements
Song & Wu Expires 10 September 2023 [Page 2]
Internet-Draft DetNet Applied to IETF NS March 2023
and associated network capabilities identified as SLOs and SLEs. The
parameters for SLOs include guaranteed minimum bandwidth, guaranteed
maximum latency, maximum permissible delay variation and Maximum
Permissible Packet Loss Rate. In order to support SLOs guarantee for
slice flows, the network resources need to be partitioned in both
control plane and data plane. [I-D.ietf-teas-ns-ip-mpls] provides a
solution to resolve this problem. It introduces NRP (Network
Resource Partition) and NRP policy to construct IETF Network Slice to
address the requirements of network slicing in packet networks. To
realize the adequate network resource allocation at control plane and
necessary network resource reservation at data plane, the resource
reservation on each link needs to be NRP aware, e.g., the traditional
technology such as RSVP-TE used at control plane is not enough, the
NRP state aware Traffic Engineering (NRP-TE) is needed.
This document describes the applicability of DetNet to IETF Network
Slice. The convergence of DetNet with IETF Network Slice helps the
deterministic service delivery with adequate network resource
allocation and reservation on each node along the path of DetNet
flows.

3. Applicability of DetNet to Network Slice
3.1. Use Case
Refer to [RFC8578] the use case of DetNet applied to Network Slicing
is described in section 10:
* Resource distribution across slices.
* Deterministic services within slices.
The IETF Network Slicing enables a diverse set of applications with
different SLOs (Service Level Objectives) guarantee to coexist over a
shared underlay network. The NRP defined in
[I-D.ietf-teas-ns-ip-mpls] provides one solution to address SLO
guarantee problem. With the use of NRP and NRP policy network
resource allocation and reservation are achieved at each node in IP/
MPLS network. Through the applicability of IETF Network Slice to
DetNet the sufficient network bandwidth and buffer resources are
allocated and reserved at each node along the path of the DetNet flow
to deliver deterministic service.
The following figure shows an example for the applicability of DetNet
to Network Slice.

Figure 1: DetNet mapping with Network Slice example
The App-flow user applies for low-latency deterministic service. The
packets belonging to the flow are filtered and classified to DetNet-
specific flows. The DetNet Service Instance (DSI-1) is terminated at
end system A and B. In order to meet the network resource guarantee
the user of the DetNet-specific flow applies for necessary network
resources. The IETF NSC after received the request sends NRP
profile/policy to the underlying network nodes and the underling PE
and P nodes make corresponding network resource reservation at the
right path based on path computation of NRP profile/policy. In order
to achieve adequate network resource allocation, the edge routers
(e.g., PE) should be able to identify a packet belonging to DetNet-
specific flow and its mapping with the IETF Network Slice instance.
The DetNet flow should has slice-aware capability to realize
necessary network resources allocation and reservation on each node
between the end systems A and B. At data plane the DetNet nodes
should support the NRP-ID and NRP-Label field encapsulation. Then
the added NRP-ID and NRP-Label fields parsed and processed by each
node along the path direction of the DetNet flow for the distribution
of the local NRP strategy and the reservation of network resources.
3.2. Modes of IETF Network Slice Selection
This document provides three modes of IETF Network Slice selection
operations as associated with DetNet follows. Additional modes may
be defined in the future.
* New IETF Network Slice Binding - A customer may request a DetNet
service with requirements guarantee, e.g., end-to-end latency,
latency variation, jitter, etc. To satisfy the customer's
requirements on network resource it's recommended to bind DetNet
Song & Wu Expires 10 September 2023 [Page 5]
Internet-Draft DetNet Applied to IETF NS March 2023
flows with an IETF Network Slice instance. The YANG model
described in Section 5 of this document provides the mapping
between DetNet flows with a new IETF Network Slice.
* IETF Network Slice Sharing - A customer may request a DetNet
service with requirement guarantee where a new IETF Network Slice
do not need to be created but be shared with other multiple DetNet
flows. The mapping YANG model described in Section 5 of this
document provides the mapping between DetNet flows with an IETF
Network Slice in use. No modification of the properties of an
IETF Network Slice is allowed in this mode.
* IETF Network Slice Modification - This mode allows the
modification of the properties of the existing IETF Network Slice
(e.g., bandwidth, latency, etc.).
IETF Network Slice Mapping Template - A policy profile which contains
network constraints and optimization criteria is used for mapping
DetNet flows to one/more certain IETF Network Slice instance.
4. Mapping DetNet with Network Slice
4.1. Mapping Requirements
DetNet service is per flow (including app-layer, service-layer and
forwarding-layer flow), performs traffic processing based on the
identification for flow/flow aggregation. Differences in IETF
Network Slice service are considered in terms of Network Resource
Partition. [I-D.ietf-teas-ns-ip-mpls] introduces a mechanism to
associate Network Resource Partition (NRP) with Slice-Flow Aggregate.
If DetNet applied to IETF Network Slice, the DetNet-flow/flow
aggregation is considered as the slice-flow/flow aggregation over the
underlying NRP.
Requirements for Network Slice mapping with deterministic networking
services:
* The mapping of deterministic services with underlying network
slice resources is necessary. It may include:
- Service endpoint mapping between DetNet Edge Node and IETF
Network Slice SDP.
- Access service mapping between DetNet UNI and IETF Network
Slice AC.
- Instance mapping between DetNet-flow/flow aggregations with
IETF Network Slice.
Song & Wu Expires 10 September 2023 [Page 6]
Internet-Draft DetNet Applied to IETF NS March 2023
* The creation request for network slice instance to be bounded with
one specific deterministic flow/flow aggregation instances should
be supported.
* The sharing of network slice instance for one or more
deterministic flow/flow aggregation instances SHOULD be supported.
* Configurations for a new network slice instance to provide
necessary underlying resource to deterministic services is
necessary.
* Modification for an existing network slice instance applied to one
or more DetNet flow SHOULD be supported.
4.2. Mapping Process
* APP-flow packets is instantiated as DetNet service awareness flow.
* If there is an existing IETF Network Slice instance which
satisfies the network resource requirements of the DetNet
customer. After check the feasibility of the IETF Network Slice
instance bound to DetNet flows, request mapping DetNet-flow/flow
aggregations with IETF Network Slice instance.
* If there is no IETF Network Slice available, a new IETF Network
Slice instance creation is required.
* The mapping of DetNet flow with IETF Network Slice is configured
and stored in management plane. The mapping policy of DetNet flow
associated with underlying network resource partition (NRP) is
programmed to the DetNet or IETF Network Slice Nodes (such as SDP,
P nodes, etc.) through YANG data models.
* In data plane, the DetNet or IETF Network Slice Nodes complete the
identification of deterministic service flows (such as IP 6-tuple,
MPLS labels, etc.) and correspond with one specific network slice
instance , realize the slice awareness of DetNet flow/flow
aggregation. Through the network resource occupation of hop-by-
hop nodes along the path, network resources required by the
deterministic networking service flow is guaranteed.

5. YANG Modeling Approach
This section provides how the DetNet and IETF Network Slice Service
mapping parameters are supported using augmentation of the existing
DetNet service models (i.e., [I-D.ietf-detnet-yang]). It identifies
the YANG data models being defined by the IETF to support this
deployment architecture and specific scenarios relevant for Service
Providers.
