基于加权公平的DiffServ服务质量模型的研究

On Weighted Fairness-based DiffServ QoS Model

针对在核心节点实现的主动队列管理(AQM)可以预见和防止拥塞,并且能够较公平地分配带宽,介绍了一种加权公平的主动队列管理算法,提出一个基于公平性的拥塞控制机制,即将这种AQM算法部署在可提供Q oS服务的区分服务模型中,最后介绍仿真过程并分析该模型的性能.

The problem of active queue management （AQM） implemented in core nodes is discussed to predict and prevent congestion and allocate bandwidth in a fair manner. An weighted fairness guaranteed AQM algorithm is introduced, and then a fairness-based congestion control mechanism is presented in which the AQM approach is deployed in DiffServ model providing QoS guaranties. The simulations and analysis on the performance of this model are described.
