| Abstract: | Space environment data transfer system needs to transfer massive space environment data from the ground monitoring station to the data center through Wide-Area Network (WAN). High loss rate and large delay of WAN influence the normal operation of the space environment data transfer system. In this paper, TCP congestion control mechanism is studied and the BBR congestion control algorithm is used to solve the problems of space environment data transmission. Aiming at the requirements of space environment data transmission, a workflow model of space environment data transfer is designed using Petri-net, and a space environment data transfer system based on BBR congestion control algorithm is established. Finally, it is proved by the experiments that the system is applicable to space environment data transfer on WAN. |
