摘　　要：针对大时延对计算机网络拥塞控制系统性能的影响,设计了一种基于Smith预估器的拥塞控制算法,并将其推广到多条链路的情况;该算法实现简单,适合计算机控制系统实现,在大时延网络中具有实际应用价值;仿真结果表明,该算法动态响应快,能够有效克服大时延对系统性能的不利影响,大大抑制了队列的不稳定振荡,提高了链路利用率。With regard to the impact of large delay on congestion control system, a flow control scheme is proposed based on Smith predictor, and this scheme is applied to the network with multi--link, The method is easy to implement and has a practical application in large --delay networks, The simulation results show that this algorithm is obviously superior to that of the original scheme in the large--delay network , and can increase the link utilization.
