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.
