This data set contains data related to the paper 'TrafPy: Benchmarking Data Centre Network Systems'. The data have been split into 3 files to avoid needing to download all data sets if only some are needed:1) plotData: The data plotted in the paper for each of the benchmarks averaged across 5 runs.2) trafficData: The flow-centric traffic requests used in each of the simulations.3) simulationData: Each individual benchmark run. Contains full access to the simulation history, metrics, and so on. When unzipped, this file is ~2.5 TB in size.
