Worst case response time analysis of hard real-time sporadic traffic in FIP networks
P. Pedro, Alan Burns · 2002
Real-time field buses are currently a significant issue in both process control and manufacturing areas. They constitute the base upon which real-time fault-tolerant distributed systems can be designed for these application areas. A potential large leap towards the use of Fieldbus in such time-critical applications lies in the evaluation of its temporal behaviour. In particular an important problem associated with the Fieldbus FIP is its inability to guarantee the timing performance of sporadic traffic. In this paper we develop the pre-run-time schedulability analysis of FIP bounding the worst case response time of the sporadic traffic.
