Satellite terminal bursty traffic model and queuing performance analysis
Bie Yuxi · Journal of Computer Applications · 2014
With the increase of application of satellite networks in emergency communication, and continuous growth of satellite terminal service types, the traffic may experience an instant augmentation showing a significant burst, and the data flow on the terminal also presents self-similarity. A method was proposed to generate satellite terminal self-similar traffic flow by using a superposition ON / OFF model with heavy-tailed distribution of time interval. And the effect of input of self-similar traffic flow on the packet loss rate, delay, and delay jitter was discussed, as well as the requirements on effective bandwidth. The relationship between packet loss rate at network terminal, delay, delay jitter and system cache was obtained by simulation, based on which, a method was put forward to reduce delay and decrease packet loss rate, providing theoretical support for efficient information transmission under condition of limited bandwidth and system cache.
