Traffic estimation with short-term fluctuating component

Abstract

In network design, predicting the fluctuation of the amount of traffic is important to determine the required bandwidth. Measuring traffic volume in a short time interval is one solution. However, the measurement imposes a load on the measurement equipment. This paper shows the methodology of estimation of a short-term fluctuating component by using information about the peak rate of each traffic source. We propose a statistical methodology of estimating the maximum traffic volume and maximum short-term fluctuating component by only using the peak rate of each traffic source and the average traffic volume. This method is very useful for management of a network because the maximum traffic volume is estimated without measuring traffic within a short time interval.
