| Abstract: | 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. |
