These striking images are 3D hyperbolic graphs of Internet topology. They are created using the Walrus visualisation tool developed by Young Hyun at the Cooperative Association for Internet Data Analysis (CAIDA). The underlying data on the topological structure of the Internet is gathered by skitter, a CAIDA tool for large-scale collection and analysis of Internet traffic path data.



Plankton visualization of the hierarchical topology of the international web cache. Developed by Bradley Huffaker at the Cooperative Association for Internet Data Analysis (CAIDA).



A topology map of a core network of a medium-sized ISP. It was created using an automatic network discovery tool called Mercator developed as part of the Scan project by Ramesh Govindan, Anoop Reddy and colleagues, at the Information Sciences Institute, USA.



Constellations of satellites, such as the Teledesic system, are being deployed to provide global network infrastructure. The SaVi (satellite visualization) system can visualise the orbital patterns of these satellites as shown in the example images here. SaVi was originally developed by Robert Thurman and Patrick Worfolk, in The Geometry Center, University of Minnesota.
