摘　　要：介绍了将拥塞计费应用到区分服务网络的流量调节机制中,与基于令牌桶的双速率三色标记器(trTCM)相结合,提出了一种基于拥塞计费的DiffServ流量调节机制(CPDTC)。仿真表明该机制不但可以保障不同属性的AF响应流之间的公平性,而且可以有效地控制网络拥塞,提高业务流的有效吞吐量。Conception of congestion pricing is applied to traffic control scheme in DiffServ networks. In this paper, combined with trTCM algorithm, a congestion pricing-based traffic conditioning scheme is proposed. Simulation results indicate that the new proposed scheme can not only guarantee fairness between AF aggregates, but also control the congestion effectively so as to improve the good throughput of aggregates in DiffServ networks.
