摘　　要：针对节点局部移动或离开所在群所引起的群布局部分和全部失效问题,研究群维护算法和群首维护算法。群维护算法设计了离群节点快速入群或重新组群的算法,确定算法中涉及的消息格式,设计了节点在正常担任群首职责期间对群成员的维护流程。通过设定群成员存活最新时间,定期进行心跳检测,实时更新群成员列表,基于消息线程分时同步处理群消息,实现了群管理的实时性和准确性,维护群结构的稳定性。The local node movement or leaving the cluster may make a part of or the whole cluster structure failure.In view of this problem,this paper studies the cluster maintenance algorithm and cluster header maintenance algorithm.In the cluster maintenance algorithms,the fast joining the cluster or reforming a new cluster for the nodes leaving the cluster is designed.The message format involved in the algorithm is determined.The maintenance flow of cluster member is designed when the node serves as the cluster leader.The new survival time of cluster member is set,the heart-beat detection is periodically done and the cluster lists are updated in real time.The messages are processed synchronously based on message threading at different time.The timeliness and correctness of cluster management is implemented.The stability of the cluster is maintained.
