Abstract:

I he selt-simtlarity degree ot network trattic is checked by computing the Hurst parameter based on the selfsimilar theory. In this paper, we capture packets on the campus network＇s backbone, and then compute the Hurst parameter to check the self-similar degree of network traffic by using the R/S met    thod and the variance-time method. The existence of self-similarity is verified by experiments. We also discuss the network traffic abnormal detection b  ased on the Hurst parameter＇s obvious changes.

Key words: network traffic, self-similar, variance-time methods R/S method
