分组传送网的QoS实现方式分析

摘要

This paper described the strategy of QoS realization in the packet transport network throughDifferServ model, introduced QoS strategy and technology such as traffic classification, traffic shaping,congestion management and congestion avoidance, then compared each strategy' s advantage andshortcoming.%通过DifferServ模型介绍了分组传送网络的QoS实现策略,分析了流分类、流量整形、拥塞管理以及拥塞避免等Qos策略的技术实现方式,并对其进行优缺点比较.
