摘要

Fault-Tolerant techniques are often employed to provide predictable performance in the presence of malfunction of embedded real-Time systems. Our research addresses the problem of restoring real-Time systems to a prior state when a fault generates errors. In this paper, we first define the state restoration problem in real-Time systems, explaining when is necessary to restore a real-Time system to a prior state. We then make a thorough comparison of two important state restoration schemes, viz. backward error recovery and failure recovery, in an integrated framework. The comparisons give us an in-depth study of both schemes and allow us to characterize the kinds of fault-Tolerant problems in real-Time applications that each scheme is best suited to deal with. Finally, we propose a novel technique to avoid the domino effect that may arise when backward error recovery takes place.
