Abstract

This paper proposes to use histograms for characterising network traffic and a simple stochastic process for network performance analysis. The result of this process is the buffer occupancy histogram (queue length distribution) using a finite queue model. From this buffer occupancy histogram we detail how to obtain another interesting performance parameters like cell loss ratio and network delay distribution. The proposed method has been extensively evaluated using real traffic traces. These evaluations show that the model is accurate. Applications of this model are very wide: analysis and prediction of QoS parameters, network dimensioning and provisioning, traffic admission control, etc.

Keywords: Traffic modeling Network QoS Stochastic Analysis
