基于TCP友好性的网络流量均衡模型

Network traffic balance model based on TCP-friendly

随着多媒体流技术的快速发展,网络中的流量呈爆炸式的增长,UDP流所占的比例越来越大,具有TCP友好性的网络流量均衡是保证网络高效和稳定的重要措施。引入排队理论,采用分析的方法,提出一种考虑了网络带宽和节点缓冲区两个因素,确保UDP流的TCP友好性的前提下,使网络流量均衡的优化模型,用遗传算法进行了求解。通过仿真实验,验证了该模型的正确性。

With the rapid development of multimedia technology, the network traffic is growing explosively and the proportion of UDP flow takes more and more in it.Balancing network traffic based on TCP-friendly is an important measure to ensure high efficiency and stability of the network.This paper presents a balanced model with TCP-fi-iendly based on network load-balanced degree,which considers the link bandwidth and the buffer of every node.At last,this paper uses the genetic algorithm to find the optimal solution and gives simulation results.
