Network congestion is a serious problem for a hybrid network in Internet. In this paper we have improved the arithmetic of RED. The RED always cause that the length of average queue approximates to the max-limited length on router, and then leads to the larger delay and lower throughputs. Therefore, BP NN, which can forecast the situation of the network for a certain time, is adopted to analyses and control the length of queue on router. And then prevent the TCP stream from congestion so that the queue can transit smoothly and shorten the delay. Simulate in NS2, experimental results show that the delays of the network packets are smaller and the throughputs are higher when use BPRED on router than RED under the same Internet condition. And the TCP data stream is more powerful now.
