摘　　要：文章基于多级心跳模型,提出并实现了多入口集群调度器的环形、专用和全备份三种连接表同步模型,通过将失效节点模值指定给备份节点实现失效接管,将正常节点的连接记录和模值转移新节点实现扩展。试验表明,该方案具有很好的容错效果和扩展性。Based on heartbeat mechanism in multi-entry environment, this paper presents 3 models for connection table synchronization with their implementation, i.e. ring, full backup and special backup models. By modification of the model values of the takeover host with the values in down host, the system possesses better fault tolerance and scalability. It's particularly useful for dispatchers of the cluster that is not allowed to go down or can tolerate only a minimal amount of downtime.
