摘　　要：为解决由传输数据堆积而引发的网络拥塞问题,达到缩减网络滞后延迟的目的,设计一种基于随机检测算法的新型网络拥塞控制系统。利用LAIDS/LIDS主机随机检测架构,对拥塞控制器、网络数据过滤器进行调节,完成新型系统的硬件运行环境搭建。通过传输数据拥塞定义的方式对网络中可能出现的拥塞情况进行分类处理,再根据具体判断结果选择合适的网络拥塞控制方式,实现新型系统的软件运行环境搭建。结合软、硬件结构,完成基于随机检测算法的网络拥塞控制系统设计。对比实验结果表明,与现有控制系统相比,应用新型控制系统后单位时间内传输数据堆积量的最大值不超过5.5×10^(13)TB,网络滞后延迟平均值始终低于60 ms,网络拥塞现象得到有效缓解。In order to solve the network congestion problem caused by transmission data accumulation and reduce the network delay,a new network congestion control system based on random detection algorithm is designed. The LAIDS/LIDS host random detection architecture is utilized to adjust the congestion controller and network data filter to complete the hardware running environment establishment of the new system. The congestion situations possibly appeared in the network are classified by defining the transmission data congestion modes,and then the appropriate network congestion control mode is selected according to the specific judgment results to realize the software running environment establishment of the new system. The design of network congestion control system based on random detection algorithm is completed by combining the hardware and software structures. The contrast experimental results show that,in comparison with the available control systems,the new system′ s maximum accumulation amount of transmission data in unit time is less than 5.5×10^13 TB,and the average delay of network is always lower than 60 ms,and the network congestion phenomenon is effectively relieved.
