中文摘要：

现有网络发送数据都集中在一条最优路径上,使得网络流量不均衡,拥塞不可避免。传统的IP网络难以拓展,文章在应用层上对覆盖网络进行流量均衡,利用覆盖网络之间的互动性给出了覆盖网络的多路径流量均衡模型,在该模型上研究了输入流量和输出流量的分配算法,并通过仿真实验说明了可以有效地减小网络的端到端延迟。

英文摘要：

The transmission of data in existing networks always concentrates on the optimal route.As a result the traffic of network is not balanced,and the network congestion cannot be avoided.Traditional IP network is hard to be expanded;the paper researches on the traffic balance of overlay network on application layer.By utilizing the interactivity between overlay networks,it presents a multi-path routing traffic balance model for the overlay networks,and researches the allocation algorithm of input traffic and output traffic based on this model.Then the simulation is carried out to show that it can reduce end-to-end delay effectively.
