TSN (EN)

Definition

Time-Sensitive Networking (TSN) is a set of standards that enables deterministic real-time communication in Ethernet networks. TSN guarantees time-accurate data transmission through mechanisms such as Traffic Shaping, Scheduling, and Prioritization. In combination with OPC UA, TSN enables the convergence of IT and OT networks on a common infrastructure and is crucial for time-critical applications in Industry 4.0. The precise configuration of TSN parameters on all switches and end devices is crucial to avoid time delays.
