摘      要：Recently, the phenomenon of software aging, one in which the state of a software system gradually de-grades with time and eventually leads to performance degradation or crash/hang failure, has been reported. The agingphenomenon is ubiquitous in all kinds of software systems and hard to eliminate thoroughly. A proactive techniquecalled software rejuvenation has been proposed[13] to counter the aging problem and increase the software availabili-ty. In this paper, we systematically investigate the basic motivation, concept and development of software rejuvena-tion, and then, detailedly analyze the main research work on it. At last, a prospect about the future research direc-tions is outlined.
