摘要： 结合组通信协议的原子性、次序性、实时性和容错性,介绍了目前国外组通信协议的研究现状,然后提出一个可靠的组通信协议。该通信协议所满足的四元组可表示为<最终原子性,全序性,非实时性,1-级容错性>。实现了以下关键技术:消息丢失检测和重传机制,拥塞控制机制,虚拟同步机制和缓存机制。

Abstract: On the basis of the properties of group communication protocol: atomicity, ordering, real-time delivery and fault tolerance, the paper introduces the present situation in group communication protocol , and brings forward a reliable group communication protocol RGMP , implements the following pivotal techniques: the mechanism of detecting the losing message and repeat transmitting message, congestion controlling mechanism, synchronous mechanism and cache mechanism.
