Abstract
Software reliability is one of important characteristics for most systems. Due to dynamic properties of the system, the probability of number of visits to each component might change after a certain amount of period. To maintain the software system reliability, this paper proposed a dynamic reliability maintenance mechanism based on resource monitoring and redundant resources allocation. An open-source monitoring software, namely Glassbox, was employed to monitor the change of number of visits to a component. Then the path-based method was used to analyze the reliability of software system at the component level in run time. Sensitivity of each component was calculated using the path-based model. A greedy algorithm for re-allocating resources dynamically was proposed according to component sensitivity. Finally, some simulation experiments were conducted to evaluate the proposed mechanism. The results have shown that the proposed method is effective.
