flow-models: A framework for analysis and modeling of IP network flows
Piotr Jurkiewicz · SoftwareX · 2021
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 flow-models, for creating 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.
