High-speed calculation method of the Hurst Parameter based on real traffic

Recent studies on traffic measurement analysis in the various networks (LAN . MAN, WAN) have shown that packet traffic exhibits Self-Similarity, The pa cket traffic represents some behavior quite different from what it has been assumed. Some papers reported that Self-Similarity degrades the network pe rformance, such as buffer overflow and network congestion. Thus, we need ne w network control scheme considering Self-Similar properties. The control s cheme requires high-speed calculation method of Hurst Parameter. In this pa per, we propose high-speed calculation method of Hurst Parameter based on t he Variance-Time Plot method, and show its performance. Furthermore, we try to apply this method to the simple network control, in order to show effec tiveness of the network control with Self-Similarity.
