拥塞控制中的随机检测算法研究

作为主动队列管理（AQM）的典型代表，RED（Random Early Detection）算法得到了较为广泛的应用。出于改进其稳定性和公平性的考虑，研究者开发出了ARED，SRED，FRED，RIO和WRED等几种算法。重点研究了RED及其多种变种方法的设计思想、算法，并比较了它们的优缺点。在此基础上，分析了IP复接器中适用的算法。

Researches on random early detection of congestion control

As the typical representation of active queue manangement(AQM),RED(Random early detection) has been applied abroad.The several varied algorithms such as ARED,SRED,FRED,RIO and WRED are developed in order to improve its stability and equity.This paper deals with the design idea and algorithm of RED and its varied formats,as well,compares these algorithms.Based on the above analysis,it analyzes the use of algorithms in an IP multiplexer.
