摘　　要：区分服务模型是现代大规模网络保证IP QoS的主要模型,该模型是当前互联网通讯性能方面研究的热点问题。在改进RIO-C算法的基础上,提出了一种适合于区分服务模型的主动队列管理算法-PFRIO(RIO based on Priority and Fair)。该算法提高了带宽分配的公平性,增强了网络对突发数据流的处理能力,有效改善了区分服务模型的总体性能。DiftServ model is a main model that guarantee IP QoS in modem-large-scale network,and it is a hot issue in improving network communications properties currently.This paper improves a Active Queue Management algorithm-PFRIO （RIO based on Priority and Fair） that is suitable for DiffServ model based on RIO-C.The algorithm increases the fair for bandwidth allocation,increases the network＇s capacity to manage sudden data flow,and improves the overall performance of DiffServ model effectively.
