Abstract

Abstract: DiffServ model is a main model that guarantee IP QoS in modern-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.

Key words: DiffServ, QoS, priority, active queue management

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。
