摘要
提出了一种基于中心环旋转木马的高效分布式应用层组播模型(CRCL)。CRCL采用层次环状结构,以中心环为基础,每个中心环节点组建自己的旋转木马,通过创建节点优先级,使高优先级节点位于上层环中。通过仿真实验对比表明:该模型在中小型流媒体应用中具有很高的数据传输率、较短的收敛时间,同时平均路径长度也较小。
A distributed application layer multicast model based on Central Ring Carousel algorithm was proposed.The model employed ring as the basic topology unit,constructed carousel on each central node,and built its upper rings topology according to each node s priority.The simulation results indicate that CRCL can improve the performance of streaming media application efficiently,especially in data transmission,convergence time and average path length.
