Time-Sensitive Networking (TSN) is a set of standards under development by the Time-Sensitive Networking task group. These extensions in particular address transmission with very low latency and high availability. Applications include converged networks with real-time audio/video streaming and real-time control streams which are used in automotive applications and industrial control facilities.

Our research group focuses on modeling and analyzing networks with the goal of optimizing resource usage. This is achieved either by enhancing existing models or by developing our own IEEE 802.1Qbv model based on time-continuous Petri nets.

Additionally, we are in the process of building our own TSN testbed, which will enable us to evaluate and validate our models in real-world scenarios.
