摘要
在互联网中,一个好的速率分配算法必须公平的反映用户的效用.基于TCPvegas版本,使用优化理论解决网络中的一组对偶问题———用户效用值最大和链路拥塞值最小,实现网络带宽的合理分配,避免网络拥塞的出现.仿真实验证实了新算法使得平均队列长度、瓶颈链路吞吐量两个指标优于TCPvegas.
In the internet,a good algorithm of rate allocating must impartially reflect the utility of users.Based on the TCPvegas,the optimization theory is used to slove the dual problem about maximizing the utility of users and minmizing the congestion value of a link, fairly allocating the bandwidth and avoiding the congestion in the network.The experiments of simulation prove that the new algorithm is better than TCPvegas at average queue length and thoughout of bottleneck.
