摘　　要：本文在Byzantine fault tolerant状态机复制容错系统研究基础上,将主复件故障划分为Muteness故障和Non-Muteness故障,对主复件进行Muteness故障检测。当系统中主复件故障只是Muteness故障时,Muteness故障检测结果可以缩短view change时间,优化系统性能,提高了系统可用性。Different from BFT algorithm, the paper classifies failures into two types： Muteness failures and Non-Muteness failures. Muteness failures are detected by muteness failure detector. When the faulty primary replica is muteness failure, ＂view changes are triggered faster by the result of muteness detector. The optimization provides orders of magnitude improvements in performance of BFT during the faulty primary replica is muteness failure.
