组通信系统中组成员关系服务的设计和实现

Design and implementation of group membership service in group communication system

在组通信系统中,成员关系的维护是一个非常重要的模块,它保证消息的次序传递和虚同步。为了使一个组中节点的数目易于扩充,采用多播树的层次结构来组织节点;当成员关系发生变化时采用一种一致性算法使得视图达到一致。在此基础上设计和实现了一个有效的组成员关系服务模块。

In group communication system, group membership service is a very important module that guarantees the ordering delivery of messages and virtual synchronization. In order to expand the number of nodes, a multicast tree is applied to organize the structure of nodes. When membership changes a, consensus algorithm is applied to obtain a consensus view. Based on the above, an effective group membership service module is designed and implemented.
