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!
