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

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 self-similarity 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.
