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

Internet-Draft EDP Framework for Scaling Deterministic March 2023
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
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 in large-
scale networks. The Enhanced DetNet Data Plane (EDP) is required to
support a data plane method of flow identification and packet
treatment. [I-D.xiong-detnet-enhanced-detnet-gap-analysis] has
described the service requirements and characteristics of scaling
deterministic networks and analyzes the existing technologies gap for
EDP especially applying the DetNet data plane as per [RFC8938].
[I-D.ietf-detnet-scaling-requirements] has described the enhancement
requirements for EDP. 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 EDP such as IP/MPLS/SRv6 Data Plane.
This document proposes the enhancement of packet treatment to support
the functions and metadata for Enhanced DetNet Data plane (EDP). It
describes related enhanced controller plane considerations as well.

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.

Figure 1: Enhanced Functions in DetNet Data Plane Protocol Stack
3.1.1. Flow Identification
From the perspective of differentiated services requirements in
[I-D.xiong-detnet-enhanced-detnet-gap-analysis] section 3.1.1, 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 identification
of multiple flows and the differentiated deterministic QoS for each
DetNet flow.
According to the gap described in
[I-D.xiong-detnet-enhanced-detnet-gap-analysis] section 3.3.1, this
document proposes the enhanced DetNet data plane to support flow
identification of DetNet differentiated services with service-level
identification. It may downscale the network operations with a large
number of deterministic flows and network nodes in scaling networks.
3.1.2. Deterministic Routes
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.3.2.1, 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. This
document propose the deterministic routes which 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.
3.1.2.1. Deterministic Links
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.3.2.1, 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. This document proposes the
deterministic links to provide a one-dimensional deterministic metric
to guarantee for the deterministic forwarding capabilities at
different levels.
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
Xiong, et al. Expires 14 September 2023 [Page 5]
Internet-Draft EDP Framework for Scaling Deterministic March 2023
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. Inter-domain Deterministic Routes
As per [I-D.bernardos-detnet-multidomain], technical gaps are
existing in multi-domain DetNet scenarios. 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.
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.
In the distributed scenario, deterministic loose routes are computed
on the device through routing protocols. Interior Gateway Protocol
(IGP) is used to compute deterministic routes based on deterministic-
delay inside a domain, and Border Gateway Protocol (BGP) is used to
compute deterministic routes based on accurate delay/jitter across
domains.
3.1.3. Deterministic Resources
As discussed in [I-D.xiong-detnet-enhanced-detnet-gap-analysis]
section 3.3.2.2, the reservation and allocation of queuing related
resources or deterministic latency resources should be taken into
consideration in DetNet data plane. The networks need to shield the
differences between network capabilities. Deterministic resource is
the basis for providing deterministic network services. It refers to
the 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. The deterministic links are provided and
distributed to support the deterministic resource and forwarding
capabilities.
Xiong, et al. Expires 14 September 2023 [Page 6]
Internet-Draft EDP Framework for Scaling Deterministic March 2023
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.
3.1.4. Queuing Treatment
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.
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
improved in [I-D.dang-queuing-with-multiple-cyclic-buffers]. 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 timeslot-based queuing mechanism has been proposed in
[I-D.peng-detnet-packet-timeslot-mechanism].
3.2. Enhancements of DetNet-Specific Metadata
1. deterministic latency information
DetNet forwarding sub-layer may provide the function and technology
such as multiple queuing and traffic treatment for DetNet application
flows to guarantee the deterministic latency. The DetNet data plane
may also encode the deterministic latency related information in
packets.
Xiong, et al. Expires 14 September 2023 [Page 7]
Internet-Draft EDP Framework for Scaling Deterministic March 2023
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
[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.
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-mpls-tc-tcqf].
4. Controller Plane (Management and Control) Considerations
4.1. Management and Scheduling of Multiple Queuing Mechanisms
As described in [I-D.ietf-detnet-scaling-requirements] section 3.6.1,
it is required to support the configuration of multiple queuing
mechanisms. Different queuing mechanisms may be supported at
different levels of latency, jitter and other guarantees. The
enhancement for controller plane should be provided such as
configuration data model as defined in
[I-D.guo-detnet-vpfc-planning]. And the type of queuing mechanism
and the related queuing parameters should be advertised and
configured. For example, the deterministic links with queuing
resource could be distributed by IGP protocol as per
[I-D.peng-lsr-flex-algo-deterministic-routing]. And the queuing
parameters are carried in deterministic latency information may be
selected in path computation as per
[I-D.xiong-pce-detnet-bounded-latency].
Xiong, et al. Expires 14 September 2023 [Page 8]
Internet-Draft EDP Framework for Scaling Deterministic March 2023
4.2. Distributed Deterministic Path
The deterministic routes may be loose routes in distributed
scenarios. It is required to support the distributed deterministic
routes which are established by distributed protocols such as IGP as
defined in [I-D.peng-lsr-flex-algo-deterministic-routing].
4.3. Inter-domain Deterministic Path
In scaling deterministic networks, it may across multiple network
domains, it is required to support the inter-domain deterministic
routes to achieve the end-to-end latency, bounded jitter. And the
deadline of latency and jitter of each domain and segment should be
determined and controlled. The inter-domain mechanism MUST be
considered at the boundary nodes such as BGP configurations defined
in [I-D.peng-idr-bgp-metric-credit] and PCEP solution
[I-D.bernardos-detnet-multidomain].
4.4. Deterministic Path Computation
As defined in [I-D.xiong-pce-detnet-bounded-latency], the
deterministic latency constraints can be carried in PCEP extensions
and the end-to-end deterministic path computation should be achieved
for DetNet service.
4.5. Configuration of Flow Mapping
As defined in [I-D.xiong-idr-detnet-flow-mapping], the BGP flowspec
can be used for the filtering of the packets that match the DetNet
networks and the mapping between TSN streams and DetNet flows in the
control plane.
