摘要： 提出了一种应用于多个节点集群失效检测的心跳模型。该模型包括信任度模型、投票模型和邻居链模型3个子模型。测试表明,利用这3个子模型设计实现的心跳系统能迅速、准确地定位小规模集群中失效的节点,从而能为接下来的热切换等动作做好准备。

Abstract: A multi-node heartbeat model is introduced. It includes several sub models such as trust model, vote model and neighborhood model.The focus is on the multi-node heartbeat model design and implementation. The test result shows that this model works well in small scale clusters.
