Abstract:

In order to model the modern network traffics in multi-time scales which enables the parameters to have physics meanings , the basic characteristics of the long-range dependence (LRD) in network traffics are investigated, and several essential laws required by modern network traffics are proposed. The relationships among the parameters such as Cγor cf that describes the quantitative LRD , the traffic aggregated level m and the average arrival rate λ in long-range dependence traffic are then revealed , followed by verification with real measured data. The proposed laws include the opinions that there exists LRD in network traffics indeed , certain statistically-quantitative relationships between the average arrival rate involving the TCP and IP levels , etc. and the parameter Cγ or Cf .

Key words: Internet, network traffic, self-similarity, long-range dependence, traffic model
