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 cost-effectiveness, 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 time-sensitive 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.
