Abstract

This paper addresses the challenge of efficiently transmitting video data in networked control systems while meeting stringent real-time constraints such as low latency and minimal packet loss. The objective is to develop a simple yet scalable network architecture that minimizes end-to-end delays for critical watchdog traffic, ensuring system reliability and performance. The proposed design includes three interconnected workcells with sensors, controllers, actuators, and cameras, and is capable of managing bandwidth-intensive video data alongside time-sensitive control traffic. Using delay calculations and Riverbed simulations, the study evaluates transmission, propagation, queuing, and processing delays. By implementing traffic management strategies like phase-shifting camera traffic, the solution achieves a significant improvement in delay reduction, decreasing end-to-end delays for watchdog traffic by over 95%, demonstrating its effectiveness in mitigating congestion and ensuring timely data delivery.
