Fast Simulation of Background Traffic Through Fair Queueing Networks
Large-scale network simulation is widely used to facilitate development, testing and validation of new and existing network technologies. To ensure a high-fidelity experimental environment, the authors often need to embed real devices and have the simulator running faster than real time. Since, the generation and movement of background traffic in a network simulation represents so much of the workload, they develop here techniques for modeling background traffic through switches that use Fair Queueing scheduling. Their work is an extension of earlier efforts that assumed all switches use First-Come-First-Serve scheduling.
