Coupling Source Routing with Time-Sensitive Networking

We discuss source routing over time-sensitive networks (TSN) as means to create explicit forwarding paths. The proposed source routing scheme over TSN can be used in multiple scenarios and complex topologies, with the aim to satisfy strict latency requirements of modern network applications. In this respect, we present the implementation of this technique in Mininet, exploiting the TAPRIO interface, together with SDN control and routing header encoding. We discuss evaluation results for scenarios, where source-routing and TSN scheduling are concurrently applied to protect high-priority traffic.
