In comparison with other AQM algorithms, the Proportional Integral Controller Enhanced (PIE) algorithm has been shown to better manage the queuing delay without sacrificing channel efficiency. However, when deploying the PIE algorithm to a network equipment, key parameters such as Reference Queuing Delay have to be tuned before operation and cannot be modified afterwards. In this thesis, we address the flaws of the PIE algorithm and propose a novel adaptive PIE algorithm. We observe that the Reference Queuing Delay should adapt to the network state. In addition, we propose the partial Round Trip Time (RTT) estimation method for queue length adjustment. Furthermore, we use the well-known ns-2 network simulator to evaluate the revised PIE algorithm. Our study shows that the proposed A-PIE algorithm significantly outperforms the original PIE algorithm. Gau, Rung-Hung 高榮鴻 2018 學位論文 ; thesis 41 en_US |
