Framework of end-to-end performance measurement and analysis system for Internet applications

The Internet provides only the best-effort service for users. There is no guaranteed QoS service for end users. In general, an end-to-end path of the Internet is changed by the bandwidth, delay and packet loss by time. Therefore, the measurement of the end-to-end performance is a difficult task for users who need to establish the guaranteed path for critical applications. This paper proposes a framework for measurement, analysis and application program interface to estimate the end-to-end performance for critical applications. The proposed framework is based on the combination of the historical data for previous measurements and the real-time data for current measurement. The framework is effective for applications which need to know the end-to-end performance. The preliminary measurement in this paper has been done to verify the method
