Traffic generation methods based on generative adversarial neural networks

Abstract： Traffic generation in network simulation is crucial for ensuring simulation effectiveness. Currently, common network traffic generators are typically based on a certain random model, where the generated traffic adheres to a specified random distribution. However, determining a realistic random model for actual network traffic is often challenging, leading to biases in current models when simulating real network traffic. To address these issues, this paper proposes a spatiotemporal-correlated traffic generation model based on Generative Adversarial Neural Networks (GANs). The encoding method for network traffic data is improved, and Z-score is applied to process traffic data, making the data tend toward a standard normal distribution. Additionally, a measurement method for evaluating the spatiotemporal correlation of network traffic is introduced. Experimental results indicate that, compared to existing baseline generation methods, the proposed approach averages 9% improvement in measures of authenticity and correlation.
