4.6. Cross-DetNet Flow Resource Aggregation 4.4. DetNet Flow Aggregation
The ability to aggregate individual flows, and their associated
resource control, into a larger aggregate is an important technique
for improving scaling of messaging in the data, management and
control planes. This document identifies the traffic identification
related aspects of aggregation of DetNet flows. The resource control
and management aspects of aggregation (including the queuing/shaping/
policing implications) will be covered in other documents. The data
plane implications of aggregation are independent for PW/MPLS and IP
encapsulated DetNet flows.
DetNet flows forwarded via IP have more limited aggregation options,
due to the available traffic flow identification fields of the IP
solution. One available approach is to manage the resources
associated with a DSCP identified traffic class and to map (remark)
individually controlled DetNet flows onto that traffic class. This
approach also requires that nodes support aggregation ensure that
traffic from aggregated LSPs are placed (shaped/policed/enqueued) in
a fashion that ensures the required DetNet service is preserved.
In both the MPLS and IP cases, additional details of the traffic
control capabilities needed at a DetNet-aware node may be covered in
the new service descriptions mentioned above or in separate future
documents. Management and control plane mechanisms will also need to
ensure that the service required on the aggregate flow (H-LSP or
DSCP) are provided, which may include the discarding or remarking
mentioned in the previous sections.
4.7. Flow Identification and Aggregation As described in [I-D.ietf-detnet-data-plane-framework], the ability
to aggregate individual flows, and their associated resource control,
into a larger aggregate is an important technique for improving
scaling by reducing the state per hop. DetNet IP data plane
aggregation can take place within a single node, when that node
maintains state about both the aggregated and individual flows. It
can also take place between nodes, where one node maintains state
about only flow aggregates while the other node maintains state on
all or a portion of the component flows. In either case, the
management or control function that provisions the aggregate flows
must ensure that adequate resources are allocated and configured to
provide combined service requirements of the individual flows. As
DetNet is concerned about latency and jitter, more than just
bandwidth needs to be considered.
Section 3 introduces the use of the IP "6-tuple" for flow From a single node perspective, the aggregation of IP flows impacts
identification, and Section 4.5 goes on to discuss how identified DetNet IP data plane flow identification and resource allocation. As
flows use specific QoS mechanisms for flow-specific traffic discussed above, IP flow identification uses the IP "6-tuple" for
treatment, including path control and resource allocation. flow identification. DetNet IP flows can be aggregated using any of

found in [RFC7551]. found in [RFC7551].
4.9. Aggregation Considerations
The use of prefixes, wildcards, bitmasks, and port ranges allows a
DetNet node to aggregate DetNet flows. This aggregation can take
place within a single node, when that node maintains state about both
the aggregated and component flows. It can also take place between
nodes, where one node maintains state about only flow aggregates
while the other node maintains state on all or a portion of the
component flows. In either case, the management or control function
that provisions the aggregate flows must ensure that adequate
resources are allocated and configured to provide combined service
requirements of the component flows. As DetNet is concerned about
latency and jitter, more than just bandwidth needs to be considered.

Balazs Varga 7. Security Considerations
Loa Andersson Security considerations for DetNet are described in detail in
[I-D.ietf-detnet-security]. General security considerations are
described in [I-D.ietf-detnet-architecture]. This section considers
exclusively security considerations which are specific to the DetNet
IP data plane.
Tal Mizrahi Security aspects which are unique to DetNet are those whose aim is to
provide the specific quality of service aspects of DetNet, which are
primarily to deliver data flows with extremely low packet loss rates
and bounded end-to-end delivery latency.
David Mozes The primary considerations for the data plane is to maintain
integrity of data and delivery of the associated DetNet service
traversing the DetNet network. Application flows can be protected
through whatever means is provided by the underlying technology. For
example, encryption may be used, such as that provided by IPSec
[RFC4301] for IP flows and/or by an underlying sub-net using MACSec
[IEEE802.1AE-2018] for IP over Ethernet (Layer-2) flows.
Yuanlong Jiang From a data plane perspective this document does not add or modify
any header information.
Andrew Malis At the management and control level DetNet flows are identified on a
per-flow basis, which may provide controller plane attackers with
additional information about the data flows (when compared to
controller planes that do not include per-flow identification). This
is an inherent property of DetNet which has security implications
that should be considered when determining if DetNet is a suitable
technology for any given use case.
Carlos J. Bernardos To provide uninterrupted availability of the DetNet service,
provisions can be made against DOS attacks and delay attacks. To
protect against DOS attacks, excess traffic due to malicious or
malfunctioning devices can be prevented or mitigated, for example
through the use of existing mechanism such as policing and shaping
applied at the input of a DetNet domain. To prevent DetNet packets
from being delayed by an entity external to a DetNet domain, DetNet
technology definition can allow for the mitigation of Man-In-The-
Middle attacks, for example through use of authentication and
authorization of devices within the DetNet domain.
