HiPNet 2021 - 3rd International Workshop on High-Precision, Predictable, and Low-Latency Networking

New waves of networked applications continue to push the limits of what is possible with networks today. For
example, Industrial Internet applications, Augmented Reality, Tactile Internet require ultra-low latency measured in
single-digit milliseconds and do not tolerate no jitter at all. Economic pressures mandate increasingly cloudification
of real-time applications with precision service level needs. Many of those applications are mission-critical and cannot
afford any loss in connectivity or even single packets. Collectively, these applications require networking services
that support high-precision and predictable service levels with associated guarantees that border on determinism.
This requires a rethinking of many of the principles underlying existing "Best Effort" internetworking technology.
Various approaches are emerging to tackle those challenges. Data centers with fixed topologies and a constant
number of hops rapidly replace conventional routing and more general Internet topologies. Networks are becoming
more programmable to allow to custom-tailor and optimize treatment of packets and flows. Related technologies
range from Service Function Chaining to Network Slicing to SDN. While 5G is making URLLC at the network edge a
reality, momentum for Beyond 5G and 6G is building to push the boundaries of precision services beyond the edge
and across the core. One overarching question concerns how these technologies can be harnessed and what
additional approaches are needed to deliver on high-precision and predictable networking. This will involve advances
over all planes of network architectures, such as programming and processing of packets in the data plane, control
interfaces and ultra-low latency control loops to optimize service levels in the control-plane, high-precision
measurements and telemetry with nanosecond accuracy at scale, and related platforms and algorithms in the
management plane.
The workshop aims to provide a forum for researchers, students and professionals from industry and academia to
discuss challenges, solution approaches, and work-in-progress to deliver, manage, and control high-precision and
predictable networking services, including (Ultra) Low-Latency networks, deterministic networking, 6G, etc. The
