Monitoring faults self-consciously in the real time dual working system based on high performance network

Abstract

The time that system takes to find out exceptions cannot be too long in a real-time system. In this paper, we first construct a stochastic Petri net to analyze the relationship between the time the system takes to diagnose faults and the system's availability. We conclude that the shorter the time it takes the higher the availability it can achieve. Next, we explain how the self-detecting fault can be realized. Finally, several experiments have been designed to prove its effectiveness.
