Estimation of traffic parameters in high-speed data networks

Bellcore studies have shown that Fractional Brownian Motion (FBM) is a convenient and compact mathematical representation that can account for the burstiness and long-range auto-correlation observed in the traffic of highspeed data networks. The convenience of the FBM representation for a traffic stream lies in the fact that it is described by just three parameters ( ) m,a,H , where m is the mean rate, a the ‘peakedness’ and H the Hurst
