Abstract: The model parameters of data sources were obtained based on the characteristic of the packet onboard date system and stochastic process theory．Furthermore,the satellite network model was established by STK and OPNET.The model parameters of data sources were loaded to the LEO,and the network traffic was collected on the GEO．Lastly,R/S analysis,variance-time plots and periodogram-based analysis were applied to the Hurst parameter estimation of the degree of the self-similarity and burstiness of the satellite network traffic．Simulation results show that the satellite network traffic is characterized by self-similarity.

Key words: Hurst parameter,R/S analysis,Variance-time plots,Periodogram-based analysis,Satellite network traffic
