1. Introduction
According to [RFC8655], Deterministic Networking (DetNet) operates at
the IP layer and delivers service which provides extremely low data
loss rates and bounded latency within a network domain. The
framework of DetNet data planes has been specified in [RFC8938]. The
IP and MPLS DetNet data plane has been defined respectively in
[RFC8939] and [RFC8964]. The DetNet IP data plane primarily uses 6-
tuple-based flow identification. And the DetNet MPLS data plane
leverages existing pseudowire (PW) encapsulations and MPLS Traffic
Engineering (MPLS-TE) encapsulations.
The applications in 5G networks demand much more deterministic and
precise properties in large-scale networks. The existing
deterministic technologies are facing large-scale number of nodes and
long-distance transmission, traffic scheduling, dynamic flows, and

Internet-Draft Enhanced DetNet Data Plane Framework for February 2024
other controversial issues in large-scale networks. The Enhanced
DetNet (EDN) is required to provide the enhancement of flow
identification and packet treatment and support the enhanced
functions or mechanisms for DetNet to achieve the DetNet QoS in
large-scale networks. The Enhanced Data Plane for DetNet (EDP) is
required to support a data plane method of flow identification and
packet treatment. As per [I-D.zhao-detnet-enhanced-use-cases],
various deterministic applications are co-existed with different SLAs
guarantees in scaling networks.
[I-D.xiong-detnet-enhanced-detnet-gap-analysis] has described the
characteristics of scaling deterministic networks and analyzed the
existing technologies gaps especially applying the DetNet data plane
as per [RFC8938]. [I-D.ietf-detnet-scaling-requirements] has
described the enhancement requirements for enhanced DetNet data
plane. The EDP aims to describe how to use IP and/or MPLS, and
related OAM, to support a data plane method of flow identification
and packet treatment over Layer 3. The enhanced QoS-related
functions and metadata should be provided in scaling networks. For
example, as described in [RFC9320], the end-to-end bounded latency
depends on the value of queuing delay bound along with the queuing
mechanisms. Multiple queuing mechanisms can be used to guarantee the
bounded latency in DetNet. New DetNet-specific metadata should be
carried in data plane such as IP/MPLS/SRv6 Data Plane.
This document proposes the enhancement of the framework to support
the functions and metadata for enhanced DetNet data plane.

3. Enhancements of Enhanced DetNet Data Plane
As defined in [RFC8938], the DetNet data plane describes how
application flows, or App-flows are carried over DetNet networks and
it is provided by the DetNet service and forwarding sub-layers with
DetNet-related data plane functions and mechanisms. From charter and
milestones, the enhanced DetNet data plane is required to provide the
enhancement of flow identification and packet treatment including the
enhanced QoS-related functions and metadata in scaling networks.
3.1. Enhancements of Packet Treatment
This section proposes the enhancement for the DetNet Data Plane
Protocol Stack as shown in Figure 1 and the enhanced DetNet-related
data plane functions and mechanisms should be provided by the DetNet
service and forwarding sub-layers.

3.1.1. Flow Aggregation
From the perspective of differentiated services requirements in
[I-D.ietf-detnet-scaling-requirements], a scaling network needs to
provide the deterministic service for various applications. And the
deterministic service may demand different DetNet QoS levels
according to different application scenarios. The DetNet data plane
should support the aggregate-class level identification of multiple
flows to achieve the differentiated deterministic QoS for each DetNet
Xiong, et al. Expires 29 August 2024 [Page 4]
Internet-Draft Enhanced DetNet Data Plane Framework for February 2024
flow. It may also downscale the network operations with a large
number of deterministic flows and network nodes in scaling networks.
DetNet service sub-layer SHOULD provide the flow aggregation function
based on the classified QoS requirements to improve the scalability
in enhanced DetNet.
3.1.2. Deterministic Routes
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis], it
may be challenging to compute the best path to meet all of the
requirements and the the paths vary with the real-time change of the
network topology in scaling networks. The explicit routes may be not
appropriate for scaling networks. The deterministic routes can be
strict explicit paths or loose routes. The former is applicable to
centralized scenarios with controllers, and the latter is applicable
to distributed scenarios. Moreover, the enhanced DetNet data plane
should perform the deterministic routes and forwarding at different
classes.
DetNet forwarding sub-layer may provide the deterministic routes
function in enhanced DetNet data plane for the deterministic routing
and forwarding of traffic from ingress nodes to egress nodes.
3.1.2.1. Deterministic Links
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis], it
may be challenging to compute the best path to meet all of the
requirements within a scaling network topology pool including
multiple network metrics. The deterministic links should be used to
provide a one-dimensional deterministic metric to guarantee for the
deterministic forwarding capabilities at different levels as defined
in [I-D.xiong-lsr-detnet-deterministic-links]. The deterministic
links are provided and distributed to support the deterministic
resource and forwarding capabilities indicated by Deterministic
Class-Type (DT).
Xiong, et al. Expires 29 August 2024 [Page 5]
Internet-Draft Enhanced DetNet Data Plane Framework for February 2024
The computing end-to-end delay bounds is defined in [RFC9320]. It is
the sum of non-queuing delay bound and queuing delay bound in DetNet
bounded latency model. The upper bounds of queuing delay depends on
the queuing mechanisms deployed along the path. For example, a link
with a queuing mechanism that does not guarantee a bounded delay a
non-determinisitc link and a link with a queuing mechanism that can
provide deterministic delay is called a deterministic link. The
delay of a a deterministic link is consist of the propagation delay
of the packet on the link and the queuing delay of the packet at the
node. A deterministic link can be a sub-network that provides
deterministic transmission or a Point-to-Point (P2P) link. The
deterministic links could be distributed by IGP protocol as per
[I-D.peng-lsr-flex-algo-deterministic-routing].
3.1.2.2. Deterministic Paths
When DetNet services with different SLA requirements requested to
transmit, one or more deterministic paths may be established based on
the deterministic links. In the distributed scenario, deterministic
loose routes are computed on the device through routing protocols.
Interior Gateway Protocol (IGP)
[I-D.peng-lsr-flex-algo-deterministic-routing] is used to compute
deterministic routes based on deterministic-delay inside a domain,
and Border Gateway Protocol (BGP) [I-D.peng-idr-bgp-metric-credit] is
used to compute deterministic routes based on accurate delay/jitter
across domains.
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.3.2.1, the inter-domain deterministic routes need to be
established and provisioned in multi-domain scenarios. The stitching
of the intra-domain paths should be considered in DetNet data plane.
As per [I-D.bernardos-detnet-multidomain], technical gaps are
existing in multi-domain DetNet scenarios. In the centralized
scenario, when the source and destination PEs of a deterministic
service are located at the two ends with a limited physical range,
one controller (single domain) or multiple controllers (cross
domains) compute one or more paths with deterministic SLA according
to the typical Traffic Specification (T-SPEC) based on the collected
deterministic resources, or compute dynamically according to the
service T-SPEC as required by the services.

3.1.3. Time-based Resources Allocation
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.1.2, it is necessary to make overall resource planning and
scheduling for the network to achieve the high-efficiency of
resources utilization when provide multiple DetNet services. The
admission control policy of a flow should take into account the
deterministic resource.
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.3.2, the allocation of queuing related resources or time-
based resources should be taken into consideration in enhanced DetNet
data plane. The DetNet networks need to shield the differences
between network capabilities. Deterministic resource is the basis
for providing deterministic services. It refers to the time-based
resources that meet the deterministic indicators of a node and link
processing as well as the corresponding resource processing
mechanisms (such as link bandwidth, queues, and scheduling
algorithms). It is required to make unified modeling for all the
deterministic resources. Time-based Resources Container (TRC) is
defined to provide the time-based resources with different classes.
The container contains the corresponding scheduling resources
reserved in control plane to guarantee the capability and then the
time-based resources should be allocated in enhanced DetNet data
plane.
DetNet forwarding sub-layer may provide the time-based resources
allocation function in enhanced DetNet data plane for the allocation
of specific nodes and deterministic link time-based resources to
specific flows and classes. It also provide the admission control of
a flow to a particular class of allocated resources.
3.1.4. Queuing Mechanisms
As dicussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.3.2.3, it is required to support the enhancement of queuing
mechanisms. Multiple queuing mechanisms can provide different levels
of latency, jitter and other guarantees. The DetNet forwarding sub-
layer may provide the function and technology such as multiple
queuing and traffic treatment for DetNet application flows. The
DetNet data plane may also encode the queuing related information in
packets. The encapsulation of a DetNet flow allows the packets to be
sent over an unique queuing technology. The DetNet forwarding nodes
along the path can follow the queue scheduling carried in the packet
to achieve the end-to-end bounded latency.
Xiong, et al. Expires 29 August 2024 [Page 7]
Internet-Draft Enhanced DetNet Data Plane Framework for February 2024
The DetNet forwarding sub-layer may provide capabilities applying
existing queuing mechanisms or traffic treatment. For example, the
traffic treatment has been proposed in
[I-D.du-detnet-layer3-low-latency] to decrease the micro-bursts in
layer3 network for low-latency traffic. The time-scheduling queuing
mechanisms includes the Time Aware Shaping [IIEEE802.1Qbv] and
priority-scheduling includes the Credit-Based Shaper [IEEE802.1Q-
2014] with Asynchronous Traffic Shaping[IEEE802.1Qcr]. The cyclic-
scheduling queuing mechanism has been proposed in [IEEE802.1Qch] and
extended such as the Cycle Specified Queuing and Forwarding (CSQF)
[I-D.chen-detnet-sr-based-bounded-latency] and Tagged Cyclic Queuing
and Forwarding (TCQF) [I-D.eckert-detnet-tcqf]. The deadline-
scheduling queuing mechanism has been proposed in [I-D.stein-srtsn]
and improved in [I-D.peng-detnet-deadline-based-forwarding]. The
per-flow queuing mechanism includes Guaranteed-Service Integrated
service (IntServ) [RFC2212]. The Fair Queuing (FQ) mechanism
includes the extension such as Work Conserving Stateless Core Fair
Queuing (C-SCORE) [I-D.joung-detnet-stateless-fair-queuing]. The
timeslot-based queuing mechanism has been proposed in Timeslot
Queuing and Forwarding
(TQF)[I-D.peng-detnet-packet-timeslot-mechanism].
DetNet forwarding sub-layer may provide the queuing and scheduling
mechanisms in enhanced DetNet data plane to achieve the end-to-end
bounded latency and multiple mechanisms may be proposed to provide
different levels of bounded latency guarantees.
3.2. Enhancements of DetNet-Specific Metadata
1. deterministic latency information
DetNet forwarding sub-layer may provide the enhanced function and
technology such as multiple queuing mechanisms and traffic treatment
for DetNet application flows to guarantee the deterministic latency.
The enhanced DetNet data plane may encode the deterministic latency
related information in packets.
The information ensuring deterministic latency should be provided for
EDP. A common and simplified data fields can be defined as per
[I-D.xiong-detnet-data-fields-edp] including encapsulation in IPv6
[I-D.xiong-detnet-6man-queuing-option] , MPLS
[I-D.sx-detnet-mpls-queue] and SRv6
[I-D.xiong-detnet-spring-srh-extensions]. For example, the
encapsulation of a DetNet flow allows the packets to be sent over an
unique queuing mechanism. It is required to carry queuing related
information in data plane so as to make appropriate packet forwarding
and scheduling decisions to meet the time bounds.
Xiong, et al. Expires 29 August 2024 [Page 8]
Internet-Draft Enhanced DetNet Data Plane Framework for February 2024
2. aggregated class information
As per [I-D.ietf-detnet-scaling-requirements], the deterministic
services may demand different deterministic QoS requirements
according to different levels of application requirements. The flow
aggregation on class-level and explicit flow identification should be
supported. The enhanced DetNet data plane may also encode the
aggregated class information in packets. The deterministic latency
information and the aggregated class information as per
[I-D.xiong-detnet-data-fields-edp] may be used alone or together to
indicate the required queuing and forwarding behaviours. The
aggregated class information can also reuse the IP DSCP or MPLS TC
field.
3.3. Enhancements of DetNet IP/MPLS/SRv6 Data Plane
An IP data plane may operate natively or through the use of an
encapsulation. IP encapsulation can satisfy enhanced DetNet
requirements. Explicit inclusion of the flow identification, path
selection, queuing and traffic treatment is possible through the use
of IP options, IP extension headers or existing IP headers. For
example, the queuing information has been carried in IPv6/SRv6
networks as defined in [I-D.xiong-detnet-6man-queuing-option] and
[I-D.xiong-detnet-spring-srh-extensions].
MPLS provides a service sub-layer for traffic by adding specific flow
attributes (S-label and d-cw) in packets. MPLS provides a forwarding
sub-layer for traffic over implicit and explicit paths such as
F-Labels. Explicit inclusion of queuing and traffic treatment is
possible through the use of MPLS metadata or MPLS TC field as defined
in [I-D.sx-detnet-mpls-queue] and [I-D.eckert-detnet-tcqf].
