As the network technology has been developed, the Next Generation Internet (NGI) such as Internet2, KOREN, KREONET2 and etc has been deployed to support bandwidth of Giga bps. And, various applications such as the video conference, the tele-surgery and etc that require high bandwidth has been developed and operating on the NGI, especially KOREN and KREONET2 in Korea. When the applications are operating and happen to face some problems, various tools for traffic measurement are usually used to analyze them, and provide traffic information in each link on total flow path or other metrics such as end-to-end delay, jitter and etc in most cases. However, although with these tools most of network problems can be properly analyzed, the problem in the user’s view point can not be resolved so that which part of networks and/or which ones among user’s systems and nodes on the flow path cause the problems for the user’s flow is not discriminated Therefore, this paper designs a end-to-end performance monitoring system for the user’s flow that the user can access performance data for user’s flow on the flow route, and describes the experience about deployment on KOREN.
