  16. Gnutella interfaces

  17. Problem • what does the network look like? • how am I connected? • find "good" hosts (lots of files, reliable, etc.) • where do my search messages go? • where do results come from? • network/node diagnostics

  18. Previous work

  19. Previous work

  20. What we did • Collect data Gnutella python module • Viz in realtime! Python and TKinter

  21. A preview Network graph = Ping's layout algorithm Node size = number of files Node color and border = connection state Line color = direct/indirect connections between nodes Text = node info and search queries Interactivity = drop searches, click on nodes

  22. Demo

  23. Observations • Connectivity • Small number of “big nodes” • Searches take a long time

  24. Conclusions • Future Work • Improve layout • Viz (line width, saturation) • Node information (Profile of behavior and content) • Interactivity • Your ideas? • Python/TK is a great prototyping tool!
