摘要: 容错系统不仅会产生硬件故障,而且连续长时间的运行,系统的性能还会逐渐下降或失效,即老化现象。本文综合考虑容错系统中的硬件故障和老化现象,提出了将传统的冗余策略和软件抗衰策略相结合,并给出了该系统的时间颜色Petri网(timed-CPN)模型,并结合实例进行了分析。

Abstract: A fault-tolerant system experiences a crash due to hardware components' faults or progressive performance degradation as an "aging" phenomenon, because of running continuously for very long periods. This paper considers hardware components' faults and "ag
