Reliable multicast protocol based on hybrid bus-ring architecture

The paper first discussed the conflict between the network overhead and the scalability of the existing reliable multicast protocol,then proposed a Bus-ring Reliable Multicast Protocol(BRMP),and analyzed it in the view of architecture,the establishment of coverage network,reliability,etc.In addition,it described the reliability of multicast 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.
