【摘要】 随着QoS路由技术的发展,研究人员不断地提出新的QoS路由算法以满足多媒体业务的服务质量需求。实用的QoS路由算法在应用之前除了严密的理论分析之外,还需要足够的实验来进行实际验证。在没有实际的路由实验环境下,有必要设计性能良好的QoS路由仿真平台进行仿真实验。设计并实现了一个通用的、简单的、开放性强的QoS路由仿真器QRSIM,为QoS路由算法的性能测试构建出真实、准确的仿真平台。对随机网络拓扑生成算法进行了研究,重点分析了QRSIM的总体框架和各功能模块的实现,并给出仿真实例验证了QRSIM的可靠性和有效性。更多还原

【Abstract】 With the development of QoS routing technology, many new QoS routing algorithms have been proposed so as to satisfy the quality-of-service requirements for multimedia applications. Besides the methodistical theory analysis, enough experiments should be needed to authenticate an utility QoS routing algorithm before it is applied. So it is necessary to design an QoS routing simulation platform withgood performance for experiments, if there does not exist an actual routing experiment environoment. a versatile, simple, and open QoS routing simulator(QRSIM) was designed and implemented , which provided a real and exact simulator platform for evaluating performance of QoS routing algorithms. How to generate the random network topology was studied,and then the framework of QRSIM and its primary modules were emphasized. Finally, some simulation examples are given to validate the reliability and availability of the simulator.更多还原
