Modeling and availability analysis of nested software rejuvenation policy

摘要: Software rejuvenation is a proactive technique to counteract software aging. A new nested policy put forward in this paper. finite-state automaton used model the working process of with policy. Comparing conventional periodic policy, takes into account application-level and system-level simultaneously, specially giving emphasis on nesting. This paper solves intervals based minimum downtime compares maximum system availability policy's. The numerical results demonstrate that consumes less downtime, enhances reliability.
