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. 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>
