Abstract:

It is essential to model and generate dthe background traffic in constellation network emulation. A framework of generating fractal-shot-noise-based aggregated flow-level traffic for constellation networks is described in this article. In the model, the shot is shaped by the flow rate, and the flow ra te fluctuation is characterized by the BER of inter-satellite links, the buffer management strategy of the onboard router,and the congestion control alg
  orithm of the transport control protocol, then the packet flow is generated using the fractal shot noise process. We implement the traffic generation module in the constellation network emulation environment to generate the SCPS-VJ protocol flow. The results indicate that in contrast to the well-used st  atistics-based models, the fractal-shot-noise-based traffic generation model can generate self-similar traffic according to the network dynamics.
