Contributions for the Worst-Case Response Time Analysis of Real-Time Sporadic Traffic in WorldFIP Networks

Abstract

In this paper we address the ability of WorldFIP to cope with the real-time requirements of distributed computercontrolled systems (DCCS). Typical DCCS include process variables that must be transferred between network devices both in a periodic and sporadic (aperiodic) basis. The WorldFIP protocol is designed to support both types of traffic. WorldFIP can easily guarantee timeliness requirements for the periodic traffic. However, for the aperiodic traffic more complex analysis must be made in order to guarantee its timing requirements. This paper describes work that is being carried out to extend previous relevant work [1,2], in order to include the actual schedule for the periodic traffic in the worst-case response time analysis of sporadic traffic in WorldFIP networks.
