| 摘 要： | 从判断一个节点好坏的全过程来看，利用传统心跳故障检测器的算法还是离不开超时技术。借助于心跳器的“计数”思路，提出了一个扩展心跳故障检测器模型，允许对计数器施行递增和递减操作，心跳序列随时间上下波动，从而输出更多的用于判断节点好坏的线索，使得基于扩展心跳故障检测器的算法彻底地摆脱了超时的阴影。

| Abstract: | Judging from the process ofdistinguishing crashed nodes from correctones,we find that the algorithm with the existing heart-beat failure detector can do nothing without time-out technology.By adopting the ways and means of "counting" of existing heartbeat failure detector,an extended heartbeat failure detector model is introduced,which allows addition and subtraction on the counters.The heartbeat curve stretches up and down according to time,consequently.As a result,more hints used to distinguishing crashed nodes from correct ones are outputted,and the algorithm with extended heartbeat failure detector shakes off time-out technology completely. |
