Abstract: In response to the problem of data processing and increasing transmission speed in the modern satellite network, a label exchange-based AOS frame transmission mode is designed, so that the transmission of data frames in the satellite network is implemented, and the transmission efficiency of the network is improved. In addition, in the face of the quality of service in the space network, this paper proposed the highest response ratio polling queue scheduler algorithm based on adaptive weight, so that the network satisfied the requirements of the communication service quality, which effectively prevented the loss of cache data. The design was verified in FPGA, which proved that this design met the quality of service while ensuring efficient transmission of AOS frames.
