一种可靠可伸缩组通信系统设计与实现

组通信系统是支持一致性和容错的分布式协同系统中非常重要的组成部分.为了满足大规模协同应用的需求,文中采用了基于流言的协议与确定性协议组合的方法设计并实现了一种可靠可伸缩组通信系统SGCS.该系统主要包括可靠消息传输服务与组成员管理服务,其中基于流言的可靠多播协议和确定的消息恢复、流量控制、排序协议的组合,基于流言的失败检测协议与确定的视图一致化协议的组合以及乐观虚同步机制应用使系统具有良好的可伸缩性、可靠性和灵活性.

The Design and Implementation of a Reliable and Scalable Group Communication System

Group communication systems are powerful building blocks for supporting consistency and fault-tolerance in distributed collaborative systems. In order to meet requirements of large-scale collaborative applications, a reliable and scalable group communication system SC, C,S is designed and implemented through the combination of gossip-based protocols and deterministic protocols. This system includes reliable message transport service and membership management service. The combination of gossip-based multicast protocol and the deterministic message recovery, flow control, ordering protocols, the combination of gossip-based failure detection protocol and deterministic view consistency protocol with the optimistic virtual synchrony mechanism make SGCS have the good scalability, reliability and flexibility.
