摘　　要：对利用二次检测模式构建的基于检测点的失效检测算法进行改进:利用误判概率调整二次检测延迟时间的计算方法,动态计算二次检测时间,从而提高分布式网络中失效检测的准确性.通过实验将传统的失效检测算法以及基于检测点的失效检测算法与本文提出的改进算法进行对比,验证了在分布式系统失效检测应用中,改进的算法能够提高失效检测的准确性.An improved failure detector algorithm was demonstrated on the basis of fresh point. Using the historical probability of erroneous judgment to change the check time dynamically will increase the accuracy of failure detector in distributed network. A compared experiment of the basic failure detector algorithm, the algorithm on the basis of fresh point and the improved algorithm was conducted, showing that the improved algorithm will increase the accuracy of failure detector gradually in distributed system.
