Adaptive Method of TCP Performance in LEO Satellite Networks
Jun Zhang · Jisuanji gongcheng · 2008
The performance of TCP and the fairness are poor in LEO satellite networks because the difference among the path lengths is evident.A method is proposed to adjust TCP initial congestion window and the increasing speed of the window according to the number of satellites in the path.The new formula of increasing the congestion window is deducted.It is adaptable and can rightly treat different connections respectively.Simulation results show that the performance of TCP is improved effectively,especially when the delay is long.The fairness index is near to 1 when the connections with various delays coexist.The method is easy to implement and compatible with all kinds of TCP versions.
