The Visualizer is showing 50 nodes and communication between them. It also draws spanning trees for multicast with colored lines. In this case, an emulator is hosting all nodes and the Visualizer on a single computer. The Visualizer also works on a real network.
It is confirmed for Overlay Visualizer to be able to visualize 300 virtual nodes on an emulator. The computer in this case runs Linux over VMware on Windows XP and has a 1.7 GHz Pentium M processor.
It is confirmed for the emulator to be able to host 300,000 nodes on a computer running Linux with 7550 MB heap (java -Xmx7550m).
DHT shell provides a web interface. It can also show a routing path on a geographical map (Google Maps).
