Abstract: This paper proposes a criterion with which to differentiate classes of service on the basis of an available bandwidth metric. As the service classes are differentiated in terms of their available bandwidth values, the difference between neighboring classes must be proportional to the square of the available bandwidth of the current class. This statement is equivalent to saying that the difference in packet delay between neighboring service classes is constant. The ratios connecting minimum delay, network jitter and packet proportion are derived for different classes. Experiments carried out using an NS-2 network simulator illustrate the efficiency of the proposed criterion.

Keywords: Differentiation criterion for service classes, available bandwidth metric
