A screenshot of a 3D model of the vBNS network which connects universities and laboratories in the USA. The model was created by Jeff Brown, a researcher at MOAT, National Laboratory for Applied Network Research (NLANR), USA, using his Cichlid data visualisation software. The model is animated to show how traffic flows over the links. More information on their work can be found in the paper "Network Performance Visualization: Insight Through Animation" by J.A. Brown, McGregor A.J and H-W Braun.
