| Abstract: | 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 heartbeat 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. |

| Keywords: | failure detection detection point second detection latency packet loss |
