Flow-Level Traffic Modeling for Creating a Traffic Generator

In order to efficiently run and manage a network, the network structure must be able to express the various types of traffic flowing through the network and the elements that compose the network in a simulation network environment. This paper was aims at examining the flow-level traffic modeling in order to implement a simulation traffic generator for network performance assessment. The authors propose a traffic modeling using flow information so to improve the shortcomings founds in the packet-level modeling and application-level modeling studies in the existing traffic generator. They also suggest a classification of new and existing applications in order to resolve the issues with the application-level mechanism.
