| 摘 要： | 1.问题的提出——软件衰老 1.1 软件衰老概念在最近的很多研究中讨论了“软件衰老”现象。软件衰老是指伴随着软件的运行,系统资源逐渐耗尽或运行错误逐渐积累所导致的系统性能持续下降乃至挂起停机的现象。软件衰老现象是软件可靠性的大敌,有着非常严重的危害作用,在普通的计算中,它可能影响到结果的获取和效率,在战争和国防中,其危害就难以估量了。在文16]中记述了在海湾战争时,美军正是因为“爱国者”导弹拦截控制系统中的一个软件衰老问题,对伊拉克“飞毛腿”导弹的拦截判断出错,致死美军

| Abstract: | Recently, the phenomenon of "software aging", one in which the state of a software system gradually degrades with time and eventually leads to performance degradation or crash/hang failure, has been reported. The aging phenomenon is ubiquitous in all kinds of software systems and hard to eliminate thoroughly. A proactive technique called "software rejuvenation" has been proposed13] to counter the aging problem and increase the software availability. In this paper, we systematically investigate the basic motivation, concept and development of software rejuvenation, and then, detailedly analyze the main research work on it. At last, a prospect about the future research directions is outlined. |
