Abstract: Based on the TES(Transform Expand Sample) models of heavy traffics with certain burstiness,a new practical formula for computation of effective bandwidth of traffics was derived out.When the effective bandwidth computed by means of this formula was used as the declared bandwidth of the newly coming traffic,all the simulation results on the related measurement-based admission control(MBAC) algorithm showed that the better utilization of network could be achieved than the way of those MBAC algorithms that only used average rate or peak rate as the declared bandwidth for newly coming traffic.

Key words: heavy traffic, burstiness, effective bandwidth, admission control
