摘　　要：在区分服务网络确保转发(assured forwarding)服务中,提出一种基于动态服务规格(service profiles)的病态流控制机制。该机制在DS域的入口节点(ingress node)根据核心节点反馈的信息动态地调整病态流的当前服务规格和进入DS域的速率,达到控制病态流的目的。模拟实验表明,该机制可以有效地提高正常业务流的性能,控制由病态流引起的DS域内全局最大-最小不公平(global max-min unfairness)问题。A dynamic service profiles based method controlling ill-behaved flows is proposed for Assured Forwarding Services in Differentiated Service Networks.This method control ill-behaved flows at the ingress node according the message coming from core router of DS domain,with dynamic adjusting their service profiles and rate of entering the domain.Simulation results indicate that the approach can improve the performance of normal flow and prevent the global max-min unfairness caused by ill-behaved flows in DS domain.
