Zusammenfassung
Traffic engineering has been a highly important area since the early days of telephony. The constant increase in the complexity of multimedia networks of today requires sophisticated tools and modeling techniques to be developed and constantly improved to cope with the needs of the traffic engineer and performance analyst. Due to the very high transmission rates with respect to those of other events in the system model, many recent modeling work have used fluid sources as replacement for packet-level traffic sources. This includes both analytical as well as simulation work. The object of this paper is twofold. We first introduce new algorithms to calculate several transient measures of interest that are useful in the traffic characterization and subsequent performance evaluation of network resources. We then present a modeling environment that implements these algorithms and includes unique features to aid the user in the evaluation task.
