基于采样的gCHOKe主动队列管理算法的研究
Research on Improved gCHOKe Algorithm Based on Sampling
摘要
Abstract
Active Queue Management ( AQM) algorithm is one of very important research field of network congestion control. Focus on the fairness of the active queue management algorithm in this paper. gCHOKe is an algorithm of fair approximation of active queue man-agement. When gCHOKe hit happened, the algorithm extracts another packet and judge whether gCHOKe hit happening or not. The gCHOKe hit,whose effectiveness and the force of punishing non-response flows are the key factors to enhance the fairness algorithm,is lack of fairness. Based on gCHOKe algorithm,sgCHOKe (Sampling based gCHOKe) is proposed in this paper,through analyzing the low effectiveness of non-response flows hit,which samples several packets from queue to compare with the arrived packet and employ a new mechanism of packet-loss. The simulation results based on NS-2 show that compared with CHOKe and gCHOKe,sgCHOKe can maintain the fairness of different bandwidths better,achieving better effectiveness of non-response flows hit,with high index of network fairness.关键词
