按最小速率分配的ABR控制算法公平性的研究

A study of fairness of ABR congestion control algorithm under non max min criterion

现有的各种ABR拥塞控制算法都只能实现最大最小准则下的公平分配。文中提出了一种称为“既得利益”相等的设计思想。依据这一思想改造现有算法 ,原则上可以在原算法框架内实现任一准则下的公平性。作为例子 ,我们改造了ERICA算法 ,使得新算法能达到ATM论坛定义的按MCR成比例分配带宽准则下的公平性。仿真实验结果表明 ,新算法性能良好。

All the ABR congestion control algorithms reported are designed to achieve max min fairness In this paper,a new principle named“equal profit”principle is presented Theoretically,the algorithms designed under this principle can achieve fairness under any given criterion As an example,we redesigned the ERICA algorithm Simulation shows that the new algorithm work well under various network configurations,various traffic classes,and scale well to LAN or WAN either
