| 摘 要： | 在流媒体业务中,用于数据包转发的流媒体交换矩阵,其交换性能的优劣对系统的整个性能有着重要影响.为了测试其转发数据包的效率,需要对其发送与接收数据包进行性能监控,以便计算丢包率和数据流量.通过分析比较由系统提供的性能计数器和剖面分析工具这两种性能监控工具,提出创建公共语言运行时系统性能计数器,采取将系统性能计数器和自定义性能计数器相结合的方式,以监控流媒体交换矩阵的数据流量,并编写程序进行实现.经过测试,可以对流媒体交换矩阵的数据包流量进行有效地监测,取得了良好的效果.

| Abstract: | It is very important to increase the streaming switcher's performance in streaming application.Aimed at the performance monitor with streaming switcher,it needs a way to test the send/receive packets,and to calculate the loss factor.A way is provided by creating user CLR performance counter and cooperating with system performance counter to monitor the data flow rate of the streaming switcher after compared the performance counter with profiling tools,and developed a test program.The experiment show indicated that it is a valid way which can monitor the performance of the streaming switcher efficiently |
