An improved RED algorithm based on ascending semi-Cauchy distribution and EBP

摘要：

A queue management algorithm, called ascending semi-Cauchy distribution and Hurst coefficients Adaptive Random Early Detection, CHARED for short, was proposed based on ascending semi-Cauchy Distribution and real-time Hurst coefficients calculated by EBP. According to the Hurst coefficients of traffic, ascending semi-Cauchy Distribution of the CHARED was modified by tuning the maximum of the packet dropping probability, aiming to reduce the effect of the selfsimilarity so as to improve the performance. Simulated results demonstrate that the CHARED can be used to reduce packet loss ratio, queue delay and queue delay variability.
