摘　　要：流媒体业务是推动下一代互联网发展的主要动力之一,对其性能的测量极为重要。根据流媒体业务性能测量的要求,借鉴主动测试技术,从端用户角度提出了合理反映流媒体业务性能的指标,分析了精确测量性能指标的方法,从而设计并实现了基于主动测试的流媒体业务性能测量工具,并对设计的关键问题做了分析。测量实验表明测量工具运行健壮,测量数据精确,取得了理想的效果。Streaming media application is a key impetus for Next Generation Network （NGN）. During the developing of streaming media, streaming media performance monitoring is very important. Several indexes were proposed which can reflect the performance of streaming media application from the perspective of users. The method of measuring these indexes accurately was introduced, The stream media measurement tool based on active measurement was designed and implemented, Some pivotal problems in tool design were analyzed, The robustness and accuracy are validated by experiments.
