==BBN and ARPANET==

The ARPANET was a project of the [[IPTO]] funded by the Defense Advance Research Agency ([[DARPA]]) which evolved as the internet today. The plan for the ARPANET was developed by Licklider during his tenure as Director of the agency from 1962 to 1964. Licklider envisioned a universal network.<ref>[http://www.livinginternet.com/i/ii_licklider.htm J.C.R. Licklider And The Universal Network]</ref> Inspired by this vision, his successors [[Ivan Sutherland]] and [[Robert Taylor]] both served as IPTO director and [[Lawrence Roberts]] who served as ARPANET program manager pushed for the development of wide area communications network.<ref>[http://www.livinginternet.com/i/ii_roberts.htm Lawrence Roberts Manages The ARPANET Program]</ref> In 1968, the IPTO issued a Request for Quotation for the development of Interface Message Processors ([[IMP]]) for 140 companies, BBN submitted a detailed proposal for the project. IPTO awarded the contract to the company. The BBN team was led by Frank Heart  with [[Boh Kahn]], a communications theoretician expert responsible in error control and identifying problems related with sending data over the telephone lines; '''Severo Ornstein''' and '''Ben Barker''', in-charge of hardware development while Will Crowther, Bernie Cosell and Dave Walden were responsible for the software development. <ref>[http://www.bbn.com/about/timeline/arpanet The Arpanet Forerunner of Today's Internet]</ref> <ref>[http://www.livinginternet.com/i/ii_imp_walden.htm Looking back at the ARPANET effort, 34 years later by Dave Walden]</ref> BBN collaborated with the teams from the first four sites selected by Roberts to be connected in the ARPANET  including the University of California Los Angeles ([[UCLA]]), Stanford Research Institute ([[SRI]]), University of California at Santa Barbara and University of Utah. The UCLA Team composed of [[Vinton Cerf]], [[Steve Crocker]], '''Bill Naylor''', [[Jon Postel]], and '''Mike Wingfield''' were responsible in installing the first IMP delivered by BBN to the Network Messaging Center of UCLA and created the first ARPANET node. The first message sent through the network was "Do it to it, Truett" as a tribute to BBN engineer Truett Thach who brought the computer to UCLA from Cambridge. The exchange of communication was successful. On October 29, 1969, ARPANET was born when the SRI's SDS-940 computer with the Genie operating system was connected to second IMP through an [[AT&T]] 50 kbps line; the Culler-Fried Interactive Mathematics Centre at the University of California at Santa Barbara was added to the network followed by the University of Utah Graphics Department.
