Abstract: Visualizing end-to-end path measurement data is important for monitoring network performance, diagnosing network problems, identifying trends and faults. However, the current visualization systems, such as VisoNETUI and Smokeping, suffer from a number of shortcomings. One of the problems is to only provide static presentation on measurement results. Moreover, most systems are short of interactive model that restricts to explore more performance metrics of Internet path. In essence of archive functions, most are reluctant because it does involve too complex technical designs. In this report, we have proposed and developed new monitoring approaches to overcome these shortcomings. We build new network monitoring tool called FlashyPath for the issues addressed which visualizes interactive measurement results on multiple Internet paths. For the sake of visualizing continuous monitoring results, the tool is required to read the measurement results for every five minutes and compute averaged statistics on each client request. Having FlashyPath integrated interactive model can provide ISP and institutional operators with In the report, FlashyPath provides Internet path measurement on Round-trip time (RTT), Time-to-Live (TTL), and packet and path loss. A visual mechanism for network topology would also be useful to better understand and debug network problems with utilizing measurement result in multiple paths. The report will mainly illustrate the worked approach on user interaction and data integrity.
