摘要
通过研究和分析经典、主流失效检测算法,对基于检测点的二次失效检测算法进行改进:对心跳消息预计到达时间增加反馈修正,将网络延迟误判和丢包误判进行区分。实验结果表明优化改进的算法能提高失效检测的效率和及时性。
With the research and analysis on the mainstream and classical failure detection algorithm, the second failure detection algorithm based on freshness point is optimized：adding feedback correction for estimated arrival time of heart-beat message, distinguishing between network latency and packet loss misjudgment. Experimental results show that the optimized algorithm can improve the efficiency and timeliness of failure detection.
