Analysis of Software Rejuvenation in Clustered Computing System with Dependency Relation between Nodes

This paper investigates software rejuvenation policy for the clustered computing system with dependency relation between nodes, and reconstructs a SRN model for the software rejuvenation in clustered computing system which considers both having different node types and having dependency relation between nodes. Numerical simulations of the new model shows that the software rejuvenation strategy can significantly decrease failure rate and increase the availability of the system, and also shows that dependencies between nodes have impact on software rejuvenation policy.
