Analysis of Resource Diffusion Characteristics in BT and eMule based on Monitoring and Tracking
In P2P file-sharing systems, users file transferring and downloading behaviors are invisible and nonreproducible. In order to monitor the distribution process and diffusion characteristics in those P2P systems, we implemented a resources monitoring and tracking system for BT and eMule. It continuously retrieves the BT and eMule production servers and crawls data exchanging information among peers in real-time. The system persistently saves data for tracking and searching purposes. By analyzing some target resource files, we find that resources diffusion patterns often vary in different P2P systems. Our experiments were based on two popular Chinese websites: 5Q Zone(5q.com, BT protocol) and VeryCD (verycd.com, eMule protocol) By studying the characteristics of resources distribution, introducing three P2P resources diffusion models, and giving a quantitative resource diffuseness formula, it concluded that basing on the early-stage distribution trends of a resource file, it is possible to predict its overall distribution pattern later on, which provided a screening guidance to better monitor or track resources in these systems.
