Modeling and analyses of operational software system with rejuvenation and reconfiguration

Abstract

In this paper, a software rejuvenation model with reconfiguration is proposed to improve the software performance. Firstly, continuous-time Markov chain is adopted to describe the system model. Then, the formal definitions and analyses of system availability and throughput are given. Finally, some numeric experiments are done. The results show that the presented method is effective and adopting reconfiguration can improve the system throughput though the availability has a trivial reduction.
