A new approach to bandwidth requirement estimation and its accuracy verification

We propose an estimator of the effective bandwidth, called Gaussian estimator using buffer measurement, for superposition of sources in IP networks. Our estimator does not rely on a specific traffic model and works only based on a small set of measurements of the workload in the buffer of a router. We conducted simulation experiments by using real traces, which were collected on a LAN at Chiba University and collected at an US-Japan link of WIDE backbone, and show that our proposed estimator performs better than other existing estimators that rely only on the measurement of traffic amount from sources.
