一種新的適用于多種公平準(zhǔn)則的ABR流控算法的設(shè)計(jì)和研究
A NEW ABR CONGESTION CONTROL ALGORITHM ACHIEVED FAIRNESS UNDER SEVERAL CRITERIA

摘要: 現(xiàn)有的各種ABR擁塞控制算法都只能實(shí)現(xiàn)最大最小準(zhǔn)則下的公平性。本文提出了一種稱(chēng)為動(dòng)態(tài)帶寬分配(DBA)的控制算法,在該算法框架內(nèi)可以方便地實(shí)現(xiàn)ATM論壇定義的任一準(zhǔn)則下的公平性。仿真實(shí)驗(yàn)結(jié)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. -
