As Proportional-Integral-Derivative (PID) controller provides almost the efficient method to enhance the performance and the stability, this paper further studies the 2nd order difference equation in Adaptive Random Early Detection (2DE-ARED) algorithm  to verify the stability and performance comparing to PID approach. We have conducted the experiments based on the NS-2 simulator to examine 2DE-ARED against both ARED and PID controller. Simulation results show that 2DE-ARED is able to keep the instantaneous queue length more stable and it has better control capability both ARED and PID in terms of performance of both goodputs and loss rate than.
