With the development of technology, the network environment on civil aircraft gradually tends to it in daily life. In order to avoid congestion, link data on aircraft needs active queue management. This paper proposed an IPD-RED algorithm with self-adjusting coefficients, which based on the PD-RED algorithm. IPD-RED algorithm introduced the adjustment functions of proportional coefficient and derivative coefficient to reduce the influence of parameter selection on the algorithm. Considering the queue deviation after normalization, the adjustment function used it as the parameter in order to make the coefficient change dynamically. IPD-RED designed the adjustment function according to the law of coefficient change. The experiment analyzed the improvement effect of the algorithm by changing the combination of upper and lower threshold values, the delay between routing nodes and the number of end nodes, and explored the impact of the initial value on the performance of the algorithm by changing the initial value of proportional coefficient and derivative coefficient. NS2 simulation results show that IPD-RED algorithm makes the average queue length closer to the expected value, improves the throughput and reduces the packet loss rate. The influence of initial value shows that increasing the proportional coefficient in a certain range can make the average queue length faster and closer to the expected value and reduce the packet loss rate, but it increases the delay and oscillation. The dynamic range of the derivative coefficient is very large and has little effect on several network performance parameters. In practical application, the appropriate selection of the initial value of the coefficient can make the algorithm better adapt to the business on the aircraft.
