On Hard Realtime Traffic in Converged Time-Sensitive Networks

Time-Sensitive Networking (TSN) extends IEEE Ethernet with realtime capabilities providing standardized support for multiple traffic classes within a shared network. While TSN-capable devices are becoming increasingly available, practical experience with managing traffic of varying realtime requirements in a converged infrastructure remains limited. In this paper, we present insights into the hardware and software configuration of a TSN testbed designed to support data streams of mixed criticality. In an evaluation, we apply different methods for isolating hard realtime streams from other traffic and analyze their impact on latency and jitter.
