Methodology for passive analysis of a university Internet link
Passive monitoring of Internet links can efficiently provide valuable data on a wide variety of network performance measures. We use two publicly available monitoring tools (CoralReef and NeTraMet), exploring their synergy and relevance for collecting and analyzing Internet flow data. We consider measurement design issues, then present two case studies that use these tools to analyze an Internet connection at a large university. We illustrate and discuss the potential for investigating operational and research questions using our passive measurement methodology.
