一种新的适用于多种公平准则的ABR流控算法的设计和研究
A NEW ABR CONGESTION CONTROL ALGORITHM ACHIEVED FAIRNESS UNDER SEVERAL CRITERIA
-
摘要: 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性。本文提出了一种称为动态带宽分配(DBA)的控制算法,在该算法框架内可以方便地实现ATM论坛定义的任一准则下的公平性。仿真实验结果表明,新算法性能良好。

Abstract: All the ABR congestion control algorithms reported are designed to achieve max-min fairness. In this paper, a new algorithm named dynamic bandwidth allocation algorithm is presented. Under the same framework, the algorithm can achieve fairness under several given criterion. Simulation result shows that the new algorithm works well under various network configurations, various traffic classes, and scale well to LAN or WAN either. -
