MAE-East
The MAE (later, MAE-East) was the first Internet Exchange Point (IXP). It began in 1992 with four locations in Washington, D.C., quickly extended to Vienna, Reston, and Ashburn, Virginia; and then subsequently to New York and Miami. Its name stood for "Metropolitan Area Ethernet," and was subsequently backronymed to "Metropolitan Area Exchange, East" upon the establishment of MAE-West in 1994. The MAE predated the National Information Infrastructure plan, which called for the establishment of IXPs throughout the United States. Although it initially had no single central nexus, one eventually formed in the underground parking garage of an office building in Vienna, VA.
