摘要
对通信网络的大量研究表明,网络业务本质是自相似的(相关函数上表现为长相关特性)。网络业务的统计自相似性主要是指在不同时间尺度上观测到的业务流量序列具有相同的统计特性。讨论了当前网络业务流的特性;分析了现有的自相似业务流模型。为在线测量网络中的高速业务流,根据实测时间序列数据建立合适模型提供了参考。
A great deal of research on telecommunication network indicate that the network traffic is self- similar in essentially (represents long range dependence on correlation function). The statistic self- similarity mostly means traffic sequence which is observed in different time scale have the same statistic characteristics. First,this paper discusses the characteristics of the modern network traffic. Then,it analyzes the existing self - similar traffic models. It provides reference for measuring the online high speed traffic in the network and establishing right model according to the time series data measured.
