René Hummen joined Belden in 2015, where he is working in the CTO Office of the Industrial Networking platform. With his work, René plays a crucial role in shaping the future of Industrial Ethernet and the Industrial Internet of Things (IIoT). He identifies and analyzes new technology trends, contributes to standardization, and advances next generation industrial network architectures. René is highly engaged in the OPC Field-Level Communications (FLC) initiative and is an active contributor in the OPC UA PubSub TSN Subgroup. His passions include Time Sensitive Networking (TSN), Software-Defined Networking (SDN), and Cyber Security. René holds a Ph.D. in Computer Science from RWTH Aachen University.

TSN Configuration – No reason for confusion!


Time-sensitive networking (TSN) enhances conventional IEEE Ethernet with a set of mechanisms that enable bandwidth and timing guarantees, e.g., for real-time communication in industrial control applications. The provision of such guarantees requires consistent end-to-end configuration of the newly introduced TSN mechanisms along the communication path. As an answer to the question of TSN configuration, the IEEE recently standardized three configuration models: a centralized, a distributed, and a combined configuration approach. These three models, however, led to a certain confusion about how to configure TSN rather than providing the answer everyone had hoped for.

This confusion in parts stems from the fact that the IEEE is developing standards with a broader scope than industrial communication. In this presentation, we therefore offer a tangible interpretation of TSN configuration based on how industrial control systems are often configured today. In doing so, we also reflect recent discussions in standardization such as in the OPC Field Level Communications Initiative.
