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

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!
