The '''National Science Foundation Network (NSFNET)''' was a program created and funded by the [[NSF|National Science Foundation]] to coordinate and promote ~~advance~~ research and education in networking in the United States. NSFNET served as a hub providing access to the five university based super computer centers created by NSF.<ref>[http://www.nsf.gov/about/history/nsf0050/internet/launch.htm The Launch of NSFNET]</ref> The five supercomputing centers connected to NSFNET include:

NSFNET was founded in 1985 with [[Dennis Jennings]] who was responsible in leading the development of NSFNET in linking ~~the~~ university based super computer networks to be able to share information and resources with each other. Jennings built NSFNET as a general purpose research network wherein the connection is not limited to the super computer centers, it ~~would~~ serve as a backbone connection for regional networks at every super computing ~~sites~~ and use [[ARPANET]]'s [[TCP]]/[[IP]] protocol. A team from the National Center for Superomputing Applications (NCSA) and Cornell University ~~of Illinois~~ built the initial backbone of NSFNET with 56 kbps lines. [[Dave Mills]] from the University of Delaware and [[Hans-Werner Braun]] of [[Merit Networks Inc.]] also assisted in building the backbone.<ref>[http://www.livinginternet.com/i/ii_nsfnet.htm NSFNET -- National Science Foundation Network]</ref>

NSFNET was founded in 1985 with significant effort by [[Dennis Jennings]], who was responsible for leading the development of NSFNET in linking university based super computer networks to be able to share information and resources with each other. Jennings built NSFNET as a general purpose research network wherein the connection is not limited to the super computer centers, it was to serve as a backbone connection for regional networks at every super computing site and use [[ARPANET]]'s [[TCP/IP]] protocol. A team from the National Center for Superomputing Applications (NCSA) and Cornell University built the initial backbone of NSFNET with 56 kbps lines. [[Dave Mills]] from the University of Delaware and [[Hans-Werner Braun]] of Merit Networks Inc. also assisted in building the backbone.<ref>[http://www.livinginternet.com/i/ii_nsfnet.htm NSFNET -- National Science Foundation Network]</ref>

In 1986, the super computer centers were officially connected and it became open to all academic networks. NSF decided to upgrade the NSFNET with private sector participation because of the rapid growth of ~~internet~~ users. In 1987, a Project Solicitation for Management and Operation of the NSFNET Backbone Network was released by NSF. [[IBM]], [[MCI]] and Merit Networks Inc. won the contract.<ref>[http://www.merit.edu/about/history/timeline_1980.php Merit History]</ref> NSFNET was upgraded to 1.5 Mbps and recorded a traffic growth rate of 20% per month. By 1992, NSFNET ~~has~~ 12 billions packets of traffic per month~~. By~~ December of the same year NSFNET was upgraded to T3. It had a capacity of 44.736 Mbps. By 1994 NSFNET recorded a monthly traffic level of 10 trillion bytes.<ref>[http://www.livinginternet.com/i/ii_nsfnet.htm NSFNET -- National Science Foundation Network]</ref>

The NSF decided to transfer the operations of NSFNET to the private sector in the midst of the rapid growth of the network. Four Network Access Points (NAPs) were developed for commercial backbones with 155 Mbps which were operated by [[Sprint]], [[MFS]], [[Ameritech]] and Pacific Bell (now [[AT&T]]). NSFNET was officially dissolved on October 30, 1995 however a very high performance Backbone Network Service ([[vBNS]]) was already in place for the ~~usedby~~ selected researchers.<ref>[http://www.nsf.gov/about/history/nsf0050/internet/anend.htm An End and a Beginning]</ref>
