Aiming at the problem of packet loss of finite-length queues caused by the characteristics of data high burst, and finally leading to a decrease in throughputin AOS space communication system, a link adaptive optimization method based on the minimization of the system packet loss rate is proposed. It combines the finite length queue,limited retransmission of the data link layer and adaptive modulation coding of the physical layer. The system packet loss rate is used as an objective function.By solving the minimum system packet loss rate to reasonably assign the retransmission times and modulation encoding schemes, the system average throughput is improved finally. The theoretical analysis and simulation results show that this method can reduce the system packet loss rate by 80% and increase the system average throughput by 4.2%, compared with the AMCA method. At the same time, reduce system packet loss rate by 90% and increase the system average throughput by 11.1%, compared with the AMCAFQS method.
