EFFECTIVE BANDWIDTH ESTIMATION OF HIGHLY RESPONSIBLE SYSTEMS BY THE RANDOMIZED BATCH MEAN METHOD

The effective bandwidth (EB) estimation of highly responsible systems is considered. A special attention is paid to the reasons causing overestimation of the EB obtained by the regenerative method. Simulations show that the basic reason of the overestimation is the random summation of the input data over regeneration cycles. Numerical results demonstrate an advantage of the randomizing for the EB estimation of highly responsible systems. If in such a system the workload excesses the predetermined threshold (or overloads the finite buffer), then an unacceptable violation of the QoS (quality of service) requirement happens. To estimate the EB in such systems, the modified batch means method with randomized blocks is proposed.
