Analysis of Software Rejuvenation Policy Based on Given-failure-probability
Liu Feng-yu · Jisuanji gongcheng · 2006
A method solving the rejuvenation intervals based on a given failure probability is put forward in this paper.The two-step failure model with rejuvenation interval and semi-Markov process are used for solving the mean rejuvenation cost based on the given-failure-probability.In addition,considering fine-grained rejuvenation consumes lower cost and less downtime,this paper adopts the nested time-based software rejuvenation policy,which takes the application-level and system-level rejuvenation into account simultaneously.And then based on the given-failure-probability,it obtains the maximum times of application-level rejuvenation,the rejuvenation interval sequence,and the minimum mean rejuvenation cost.
