基于混合式IP组播的大规模分布式仿真数据传输分配策略

A Hybrid IP Multicast Based Data Dissemination Allocation Strategy in Large Scale Distributed Simulations

在涉及到“一对多”或“多对多”数据传输时 ,人们通常假定只有广播、IP组播和多次“点对点”方式可用 ,研究点对点和IP组播两种数据传输方式的分配策略 .本文针对这些传输方式的缺陷 ,提出了混合式IP组播传输方式 ,并分析、比较了各种传输方式的性能 ,进而提出了基于混合式IP组播优先的信息流归并IP组播组分配算法 .测试表明 ,本算法优于以往相关工作 .

When considering one-to-many or many-to-many transfer methods,people used to assume that only flooding,IP multicasting and multiple unicasting (point-to-point) are available. This article brings a new transmission approach:hybrid IP multicast.Based on a detailed analysis of these data transfer methods,we present an allocation strategy,which outperforms its counterparts.
