Towards Time-Sensitive Networking Traffic Generation with PIPO-TG

Realistic traffic simulation is essential for evaluating network performance, security, and efficiency. However, modern network environments demand testers with high performance, scalability, precision, flexibility, and costeffectiveness, which current solutions struggle to achieve simultaneously. PIPO-TG has been proposed to overcome these constraints as a Tofino-based traffic generator tailored for high-performance parametrizable traffic experiments. In this work, we extend PIPO-TG capabilities to support an even more challenging scenario, a delay distribution on a nanosecond scale. We reproduce timesensitive networking (TSN) delay traces measured in a commercial TSN bridge. We demonstrate the flexibility, accuracy, and performance of PIPO-TG, making it an ideal tool for network testing in network research and experimentation.
