Methods improvement and optimization of satellites network transfer control protocol

There are several different features of satellites network compared to ground networks, such as long time delay, large bandwidth delay production (BDP), high error rate, intermittent and asymmetric links, etc. There are abundant research results indicated that it will reduce its performance and waste precious network resource if apply the traditional TCP in the satellites network directly. Transfer control protocol is a very important part to the satellites network, and it is the key to data transfer and control. Based on this point, the paper researches on the Satellites Network Transfer Control Protocol (STP), puts forward the improvement and optimization methods to the STP. It is proved that the improved STP has better performance than the traditional TCP applied in the satellites networks by simulation results using OPNET software.
