Tang Zijia · Journal of Sichuan University of Science & Engineering · 2013
In a heterogeneous network environment,in order to solve the loss tolerance problem of congestion caused by the flow fairness of TCP Vegas algorithm,the TCP Vegas congestion control algorithm and active queue control strategy are combined to carry on the analysis.Then,a kind of algorithm that combines congestion mechanism of different levels in the network model is proposed.Network simulation shows,the algorithm can avoid congestion lost packet effectively.In the network environment,the random early detection algorithm is improved,so that the new algorithm can distinguish the bursty traffic,thereby the congestion loss rate is reduced,which will also provide a good reference value of the development of high reliability network.
