NSFnet

National Science Foundation Network connecting research universities and other research centers in the United States. (See also NREN )

A wide-area network developed under the auspices of the National Science Foundation (NSF). NSFnet replaced ARPANET as the main government network linking universities and research facilities. In 1995, however, the NSF dismantled NSFnet and replaced it with a commercial Internet backbone. At the same time, the NSF implemented a new backbone called very high-speed Backbone Network Service (vBNS), which serves as a testing ground for the next generation of Internet technologies.
