Research and Modeling Analysis on Adaptive Process-level Nested Software Rejuvenation Policy of Computing System

Software rejuvenation with fine rejuvenation granularity can improve software availability and reliability and save the cost of software rejuvenation. Based on the characteristics of process which corresponds in high frequency and has complex corresponding relation. Based on coupling relation between the processes of the software systems, this paper defines the degree of restart dependence between processes in a new way, brings forward the arithmetic theory of self-adaptable mutuality topology charts of processes , sets down the nested software rejuvenation policy on process-level, and then models the software rejuvenation policy. So it can support to execute intelligentized software rejuvenation with fine rejuvenation granularity.
