【摘要】：多媒体业务在异构网络传输过程中,由于现有的QoS(Quality of Service)类映射方法存在灵活性不足的问题,从而降低了系统端到端效能。针对这个问题,该文在深入分析当前的QoS类映射方法基础上,结合用户QoE(Quality of Experience)特点,借助于网络微积分理论,构建了QoS类映射的数学分析模型,并进行了理论分析。基于该数学分析模型,该文从用户QoE角度提出了具有弹性的QoS类映射方法(Elastic QoS Class Mapping Method,EQCMM),该方法根据当前网络资源的使用情况,通过灵活地调整QoS类映射,充分利用网络现有资源,提高了端到端带宽资源的利用率,改善了系统端到端的效能。最后,通过仿真验证了该方法的有效性。
[Abstract]:Due to the lack of flexibility of the existing QoS (Quality of Service) class mapping methods, the end-to-end performance of multimedia services is reduced in the process of heterogeneous network transmission. In order to solve this problem, based on the analysis of the current QoS class mapping method and the characteristics of user QoE (Quality of Experience), the mathematical analysis model of QoS class mapping is constructed with the help of network calculus theory, and the theoretical analysis is carried out. Based on the mathematical analysis model, this paper proposes a flexible QoS class mapping method (Elastic QoS Class Mapping Method,EQCMM) from the point of view of user QoE. The method adjusts QoS class mapping flexibly according to the current network resource usage. The utilization rate of end-to-end bandwidth resource is improved and the efficiency of end-to-end system is improved by making full use of existing network resources. Finally, the effectiveness of the method is verified by simulation.
