摘要
基于区分应用提出具有层次车轮结构的应用层多播(ALM)模型,该模型在混乱情况下自愈性强、数据传输速度高。给出一种基于泛洪算法和区分应用的分层多播数据传输协议,根据不同应用使数据通过不同链路传输。依据网络状况变化动态优化系统拓扑结构。利用P2Psim在Linux下进行仿真实验,结果表明该模型可以提高ALM性能。
Based on differ-application, this paper proposes a Application Layer Multicast（ALM） model with hierarchical wheel structure. This model can resume itself and transmit data with high speed in a disordered situation. A Differ-application and Flooding based hierarchical Multicast data transmitting Protocol（DFMP） is presented to transfer data by different links according to the applications. It optimizes the topology structure dynamically according to the network status change. Simulation experiment is done under Linux by using P2Psim, and the results show that this model can improve the performance of ALM.
