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.
