| 摘 要： | 利用拥塞环境下网络业务流的混沌特性，提出了一种基于加权一阶局域法的公共拥塞检测方法.采用混沌信号处理方法对延时采样序列进行分析，能够迅速地判断出2个流是否通过了同一段拥塞链路.仿真结果表明，在长TCP(Transmission Control Protocol)流，短TCP流，UDP(User Datagram Protocol)流3种网络环境下，该方法具有比相关方法更好的性能，对于开发协同拥塞控制算法以及智能重叠网络的构建都有良好的应用前景.

| Abstract: | The chaos characteristic of traffic flows in the congested network environment was utilized to develop a novel shared congestion detection method based on a weighted first order local-region arithmetic.In this method,the end-to-end sample delay series of network flows are analyzed by the chaos signal process technique to quickly detect whether the network flows pass the common congestion links.The simulation results show that this method has better performance than other related methods in the network envir... |
