摘　　要： 网络拥塞已成为制约网络发展和应用的一个瓶颈,研究如何有效解决拥塞问题对于提高网络性能有着特别重要的意义。通过分析网络拥塞控制中的慢启动算法及其存在的问题,针对性地提出了一种基于历史连接参数和令牌技术的改进算法,该算法使用缓存表中的历史连接参数对新的连接进行初始化,以避免重新探测网络带宽的过程,减少了传输延迟,提高了网络拥塞控制性能,最后,运用NS2对该算法进行了仿真实现,为有效控制网络拥塞提供了一种解决方案。 The network congestion has become a bottleneck that restraints the network development and application. Studying how to effectively solve the congestion problem has a particular significance for improving the network performance. Through the analysis of a slow start in network congestion control algorithm and its problems, this paper presents an improved algorithm based on the historical connection parameters and token technology. The algorithm uses the historical connection parameters in the cache table to perform initialization for new connection to avoid the process of re-detecting the network bandwidth, reduces the transmission delay, and improves the performance of network congestion control. Finally, NS2 is used to perform simulated realization for this algorithm, which provides a solution for eflSciendy controlling network congestion.
