Network access point

The four Network Access Points (NAPs) were defined under the U.S. National Information Infrastructure (NII) document as transitional data communications facilities at which Network Service Providers (NSPs) would exchange traffic, in replacement of the publicly-financed NSFNet Internet backbone. The National Science Foundation let contracts supporting the four NAPs, one to MFS Datanet for the preexisting MAE in Washington, D.C., and three others to Sprint, Ameritech, and Pacific Bell, for new facilities of various designs and technologies, in Pennsauken, Chicago, and California, respectively. As a transitional strategy, they were effective, giving commercial network operators a bridge from the Internet's beginnings as a government-funded academic experiment, to the modern Internet of many private-sector competitors collaborating to form a network-of-networks, anchored around the Internet Exchange Points we know today.

This was particularly timely, coming hard on the heels of the ANS CO+RE scandal, which had shocked the nascent industry and caused commercial operators to realize that they needed to be able to communicate with each other independent of any third parties.

Today, the phrase "Network Access Point" is of historical interest only, since the four transitional NAPs disappeared long ago, replaced by modern IXPs, though in Spanish-speaking Latin America, the phrase lives on to a small degree, among those who conflate the NAPs with IXPs.
