摘要
本文在多级过滤算法的基础上，提出了一种适用于区分服务模型的QoS接纳控制算法。该算法支持对聚集类的分级接纳控制，当高优先级的聚集类的QoS要求无法得到满足时，通过拒绝低级别聚集类中大的网络流来满足高级别聚集类的服务质量要求。算法使用扩展的MF算法来找出大的网络流。理论分析结果表明，该算法具有快速的收敛特性，同时能够提供粒度更细的QoS接纳控制策略。
This paper presents a QoS admission control algorithm for Differentiated Services. Based on multistage filters algorithm, this algorithm supports admission control schemes for class-based traffics. When the QoS requirements of high-grade class can＇t be satisfied, this algorithm will try to deny some big traffic to satisfy the requirements of high-grade class. The theoretical analyses demonstrate that this algorithm has fast constringency and provides more hackly granular admission control schemes for QoS.
