The following map represents the backbone of the Internet as of August 2007. Each line depicts the shortest outgoing route from a test computer to each of more than 320,000 network nodes around the world. The map does not represent the physical or geographic location of servers, but rather is a topological representation of the various networks that combine to form the Internet. It shows the incredible number of interconnected networks owned and maintained by private companies. These networks combine to form the world Internet backbone infrastructure. This map is a product of the Internet Mapping Project. It was compiled and created by Bill Cheswick and Steven North at AT&T Labs Research, using technology and methods developed by the Lumeta Corporation.
