- Abstract
In simulation system, failures of simulation nodes and deficiencies in resources availability affect the effectiveness of simulation system. To improve the reliability of distributed simulation system, an optimized self-adaptive fault tolerance approach is proposed to improve the effect of fault tolerance and reduce the overhead. We construct the self-adaptive fault tolerance architecture based on virtualization technology. We divide the failures according to their locations and realize fault tolerance by self-adaptive selection strategy. Then three main problems of replication fault tolerance strategy are analyzed, including node selection, number of copies and location distribution. Solutions are proposed combining virtualization technology. Besides, virtual machine migration is adopted and optimized with weighted descending multi-attribute matching method to improve the performance and reduce the overhead of simulation system. Finally, we evaluate the performance of the proposed fault tolerance approach using experiment data. The effectiveness of fault tolerance is guaranteed and the overhead is controlled at a low level.
