Abstract: It is generally accepted that network traffic could be characterized by self-similarity. It is important to generate network traffic according to this principle for network performance analysis. A scheme for network background traffic generation was given, and it was validated by a program implemented in VC++. Furthermore, this procedure was used to simulate satellite network and help to analyze end to end delay. It suggests that bursty traffic has influence on satellite network performance.This factor should be carried to satellite network routing optimization and traffic allocation.

Key words: Network traffic, Self-similarity, LEO satellite network, Network simulation
