摘要:

为保证不同类型业务在传送多协议标记交换网络中的合理调度,并提高链路带宽资源利用率,提出了一种改进型的加权公平调度算法. 为分析该算法性能,利用OPNET仿真软件搭建平台进行仿真. 结果表明,相比于传统的加权公平算法,该算法在不增加算法复杂度的基础上能有效地节约链路带宽资源,并使高等级业务获得更好的时延特性.

Abstract:

An algorithm is proposed for scheduling different types of services and for improving bandwidth utilization of links in transport multiprotocol label switching network. This algorithm is implemented in a simulation testbed based on OPNET modeler for performance evaluation. Simulation is shown that, compared with traditional scheduling algorithms, the complexity of this algorithm is notincreased. And a better timedelay performance of the high class services is also verified.
