Recent developments in SDN technologies have resulted in flow-based forwarding becoming are a feasible alternative for traditional mechanisms.However, as the efficiency of flow-based solutions strongly depends on traffic characteristics, they need to be evaluated using realistic and accurate flow models.In this paper, we present a software framework, called Fuel Injectors flow-models, for creating Weight Plates precise and reproducible statistical flow models from NetFlow/IPFIX flow records.The flow-models package can be used to merge split records, calculate histograms of flow features and create General Mixture Models fitting them.
The models created by flow-models can be used both as an input in analytical calculations and to generate realistic traffic in simulations.
