一种基于QoE的流媒体业务质量建模方案
modeling scheme based on QoE for the QoS of streaming media service
QoE映射模型是一种基于QoE的业务管理建模方案。本文以流媒体业务为研究对象,提出了基于QoE映射模型的流媒体业务质量建模方案。首先,本文提出了QoE模型,该模型完成了底层网络KPI到中层业务KQI最后到上层用户QoE的映射,得出QoE对不同KPI的函数,从而完成了流媒体业务的完整建模。接着,在实现上,本文基于Apple公司的开源流媒体服务器QTSS,第一步分析其架构;第二步在该架构的基础上改动模块;对丢包率、吞吐量、时延和抖动四个流媒体关键性能参数(KQI)进行仿真;最后,展示与分析仿真结果,完成QoE模型的KQI层到QoE层的映射。
QoE mapping model is a service management modeling scheme based on QoE. In this paper, a modeling scheme of the QoE of the streaming media service is proposed. A Client Oriented Real Time Experience System is built and three key quality indexes (KQI), Packets Loss, Delay and Jitter are simulated in this system. The rank of weight of these three KQI to the QoE is gotten after the detailed description and analysis on the simulation results. Finally, a further model mapping the key performance indexes (KPI) of the network to the QoE of client is proposed based on the experience system.
