Modeling techniques to determine network performance under asymmetric traffic loads

A new strategy for modelling asymmetric traffic load distributions on local area networks (LANs) is outlined. Mathematical analysis utilizing the statistical characteristics of traffic loads offered to LANs is presented which provides a mechanism for the prediction of network performance under asymmetric traffic load distributions. Discrete event computer simulations of the token passing protocol are used to verify the predictions made by the new modelling strategy, and hence the potential value of this tool for network planners and operators is illustrated.
