摘　　要：目前,已有的流媒体业务性能测量工具主要用于对服务进行压力测试,不能反映终端用户的实际使用性能。本文从端用户角度设计了合理反映流媒体业务性能的指标,提出并实现了一种基于主动业务仿真的流媒体业务性能测量方法,能及时向流媒体服务器反馈信息,实现动态的质量控制,并为流媒体业务系统的优化提供依据。Most of the tools for measuring streaming media applications are designed for pressure test,which can not reflect the actual performance at end users.During the development of the streaming media,the streaming media performance monitoring is very important.From the perspective of end users,we propose several metrics reflecting the performance of the streaming media applications,and accomplish a measurement method,which is based on active business stimulations.A simulative experiment is designed for analyzing the influence on the streaming media performance caused by bandwidth,frame rate,packet loss and delay.According to the experimental data,our work can accomplish the dynamic control of quality and provide a basis for optimizing the streaming media business system.
