【Abstract】 In this paper, chaos characters of miniature network flow data sampled in low resolution are differentiated, using methods of nonlinear time series analysis. Firstly, a smoothing method is given for network flow data. Then, largest Lyapunov exponent of flow data is computed, and noise data with the same characters are distinguished from network flow data. From different points of view, it proofs that network flow is a chaos system. These work provide the foundation for studying behavior characters of network flow using chaotic theory.更多还原
