A flow control method for rate-adaptive-system in satellite is proposed for the significant increase in signal attenuation in rainy weather with the frequency.Based on the improved token bucket algorithm,this method can guarantee the proper bandwidth of services,by accumulation and comparison of multiple packets.It is shown that the rate-adaptive-system using the method can limit the service occupying excess bandwidth.This method has been implemented in FPGA for its low-complexity and small resource consumption.

Key words: flow control;token bucket algorithm;FPGA
