【摘要】 区分服务网络节点中的多级别的队列输出带宽由权值调度算法保证,固定权值调度在网络负载发生变化时无法继续提供公平的带宽保证。本文提出了一种动态调整权值的调度算法以达到在多服务级别间公平分配带宽。实验仿真表明,该算法可以对负载流数目的变化作出有效的响应,并快速实现调度权值的理想公平值。更多还原

【Abstract】 Class-based service differentiation is provided in DiffServ networks. However, when it is under dynamic traffic load, this differentiation will be disordered by the fixed weighted bandwidth allocation. In this paper,a fair bandwidth allocation algorithm is proposed for the scheduling among multiple service classes. Simulation results show that the algorithm can quickly response to the changes of the traffic load and adjust the weights to ideal faire values.更多还原
