摘　　要：针对网络中海量数据传输的网络拥塞控制问题,对网络流量稳定性控制的非线性模型进行了分析和模拟。结合网络中产生拥塞的原因(控制信息与数据沿同一链路传输且具有相同的时延,而每一个用户都试图最大限度地利用网络),给出了利用TurboC模拟不同带宽利用率、不同工具函数、不同经验因子情况下的网络传输情况。验证了模型的科学性、问题所在及建立脱离网络拓扑和网络协议的通用结点流量控制模型的可行性。To study the problem of network transaction's congestion control, the nonlinear model of network node's traffic control,that is put forward by Kelly and Gleen.V. et al. is simulated and analyzed. The cause of network congestion is discussed, what is control message and data transfer by the same path and with the same time delay. On the other hand, each user tries to use the path to the maximum. The simulation results of network transaction under different bandwidth use factors, different utility functions and different experience factors are given. The scientific practicability and problem of the model and the possibility to establish a general congestion traffic control model are verified.
