The Internet network topology is a slowly
changing web with thousands of lines and even
more inter-connections. The overall Internet architecture is described on the architecture page.
The near real-time network topology of the Internet -- how it is connected
and put together in practice -- can be viewed at a range of online resources,
of which are listed below.
Internet Exchange Points. The communications traffic on the
Internet backbone is exchanged at large Internet Exchange Points (IXP), sometimes
Points (NAP) or Metropolitan Area
Exchanges (MAE), constituting the top level of the Internet network topology.
The first five large NAP's in North America were established in the 1990's
San Francisco, San Jose, and Washington, D.C. The following sites maintain
current indexes of IXPs, many of which provide statistics and graphs of the
performance of their major nodes:
Data sources. The following sites provide a range of maps,
graphs, graphics, and statistics about the Internet network topology:
