摘　　要：在分析现有可靠组播协议中网络开销与网络扩展性的冲突问题后,提出了一种基于总线环型混合拓扑结构的可靠组播协议BRMP(Bus-ring Reliable Multicast Protocol),并从体系结构、覆盖网的建立、可靠性等多个方面对BRMP进行分析,叙述了该可靠组播协议的实现原理以及实现机制。仿真实验结果表明,基于NACK的BRMP协议减少了发送端的网络开销并且具有良好的可扩展性。The paper first discussed the conflict between the network overhead and the scalability of the existing reliable muhicast protocol, then proposed a Bus-ring Reliable Muhicast Protocol （BRMP）, and analyzed it in the view of architecture, the establishment of coverage network, reliability, etc. In addition, it described the reliability of muhicast protocol in the realization of the principle and implementation mechanism. The simulation results indicate that BRMP based on NACK could achieve much lower network overhead and better scalability.
