Abstract: Stream-media and real-time application standing for new network application mode presents challenges to network performance and accurate measurement, which requires ISP provide efficient monitoring means meeting service level agreement. This paper proposes a network performance measurement system named NPMFO(Network Performance Measure Frame) based on One-Way Active Measurement Protocol(OWAMP)), which is an advice of IPPM working group. It discusses the effect of packet distribution and packet size to measurement result. Simulation results validate the methodology selected in the system.

Key words: delay, packet loss rate, bandwidth
