Abstract：Transmission control technique influence communication performance in aviation network.The transmission control mechanism based on priority guarantee performance of high priority business,but a-rise poor transmission performance of low priority business and bandwidth utilization problem.For allevi-ate this problem,put forward the innovative"cognitive available bandwidth"concept and design the transi-tion and control mechanism of cognitive available bandwidth through combined with the theory of green communication and the available bandwidth estimation techniques;and self-adaptive modulation is applied to improve bandwidth utilization rate.The simulation results prove that the low priority service perform-ance is relieved based on guarantee performance of high priority service and achieve the delay shake is less than 0.02 ms through the use of transition and control mechanism of cognitive available bandwidth.The throughput rate is improved 3.26% by using self-adaptive modulation technique.
