TL;DR
This paper reviews the current state and open challenges of deterministic communications in 6G networks, emphasizing the need for seamless integration, scalability, security, and end-to-end system awareness for future cyber-physical systems.
Contribution
It identifies key limitations of existing technologies and proposes a comprehensive vision with approaches like 6G evolution, edge-cloud integration, and digital twins to enable deterministic communications in 6G.
Findings
Current systems are limited in predictability and scalability.
Integration of 6G with existing deterministic technologies is essential.
End-to-end security and system awareness are critical for future CPS.
Abstract
Over the last decade, society and industries are undergoing rapid digitization that is expected to lead to the evolution of the cyber-physical continuum. End-to-end deterministic communications infrastructure is the essential glue that will bridge the digital and physical worlds of the continuum. We describe the state of the art and open challenges with respect to contemporary deterministic communications and compute technologies: 3GPP 5G, IEEE Time-Sensitive Networking, IETF DetNet, OPC UA as well as edge computing. While these technologies represent significant technological advancements towards networking Cyber-Physical Systems (CPS), we argue in this paper that they rather represent a first generation of systems which are still limited in different dimensions. In contrast, realizing future deterministic communication systems requires, firstly, seamless convergence between these…
