Dynamic bandwidth allocation is needed to guarantee quality of service

while video traffic prediction plays an important role in dynamic bandwidth allocation. In this paper

both autocorrelation and Hurst parameter of self-similarity are illustrated to show that traffic character of original frame sequence can be represented by traffic on the time scale of GOP. A new variable step size adaptive algorithm is also presented based on the fixed step size adaptive algorithm

which is used to predict MPEG4 video traffic on large time scale of GOP. And VSSA algorithm can improve performance of prediction significantly according to a number of simulations.
