Abstract
A method for modelling a relationship between effective bandwidth coefficient (EBC) and mean throughput in a network includes: calculating an EBC for each sample packet trace of a specified traffic type, where the EBC is the ratio of the estimated effective bandwidth EB to mean traffic flow rate M of the sample packet trace; storing the EBC for each sample packet trace with the associated value of M; and modelling EBC versus M for a plurality of values of M for the specified traffic type. Calculating the EBC includes: setting a maximum packet delay target parameter and a violation target parameter for a specified traffic type; collecting a sample packet trace of the specified traffic type from a selected measurement point on the network; estimating the EB of the sample packet trace using the maximum packet delay target parameter and a violation target parameter; and calculating the EBC for the sample packet trace as EBC=EB/M.
