| 中文摘要: |
| 近年来,关于因特网业务量多重分形性的研究已成为网络通信研究领域的一个热点.目前,在关于这一多重分形性的成因方面已经有了一些研究成果,大部分都认为这是由现代网络分层的体系结构造成的.然而这些结论对现代因特网的负载极重这一事实及其对网络业务量性质的影响没有给予充分的重视.通过对已有成果的研究,结果表明,在网络处于重负载的条件下,业务量多重分形性是由于TCP(transmission control protocol)独特的发送行为和多个TCP连接的汇聚造成的.为了支持这一结论,利用小波分析、模型模拟分析、实际数据计算等手段,从多个方面进行了论证.由于该发现是由现代因特网的实际情况得出的,因而比某些现有的结论更加接近实际,并且对因特网的网络设计和性能估计等方面具有重要的理论指导意义和实际使用价值. |

| Recently, the study on the multifractal nature of Internet traffic has been becoming a hot-point in the field of study on communication networks. There have been some results on the problem of the source ofmultifractal in Internet traffic, most of which think that the source comes from the hierarchical feature of networks protocols. However, these results ignore the fact that the traffic load in modern Internet is very heavy, which makes important effects on traffics. After analyzing the existing results, it is found that,in the case of heavy loading,the source of the multifactal in Internet traffic is the aggregation of lots of TCP(transmission control protocol)connections,as well as the particular sending behavior of TCP protocol.To support the find,means of wavelet analysis,simulation,and practical data calculating are used.As the find is concluded on the base of practical case in Moden Internet,it is more approach to the truth than existing results,and is more valuable in neworking designing and performance evaluating. |
