ARPANET - Wikipedia, the free encyclopedia. The Advanced Research Projects Agency Network (ARPANET) was an early packet switching network and the first network to implement the protocol suite TCP/IP. Both technologies became the technical foundation of the Internet. ARPANET was initially funded by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense.

Access to the ARPANET was expanded in 1. National Science Foundation (NSF) funded the Computer Science Network (CSNET). In 1. 98. 2, the Internet protocol suite (TCP/IP) was introduced as the standard networking protocol on the ARPANET. In the early 1. 98. NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in 1.
NSFNET project, which also created network access to the supercomputer sites in the United States from research and education organizations. ARPANET was decommissioned in 1. History. Prior to the advent of packet switching, both voice and data communications had been based on the idea of circuit switching, as in the traditional telephone circuit, wherein each telephone call is allocated a dedicated, end to end, electronic connection between the two communicating stations. Such stations might be telephones or computers. The (temporarily) dedicated line is typically composed of many intermediary lines which are assembled into a chain that stretches all the way from the originating station to the destination station. With packet switching, a data system could use a single communication link to communicate with more than one machine by collecting data into datagrams and transmitting these as packets onto the attached network link, as soon as the link becomes idle. Thus, not only can the link be shared, much as a single post box can be used to post letters to different destinations, but each packet can be routed independently of other packets.
Licklider of Bolt, Beranek and Newman (BBN), in April 1. Those ideas encompassed many of the features of the contemporary Internet. In October 1. 96. Licklider was appointed head of the Behavioral Sciences and Command and Control programs at the Defense Department's Advanced Research Projects Agency (ARPA). He convinced Ivan Sutherland and Bob Taylor that this network concept was very important and merited development, although Licklider left ARPA before any contracts were assigned for development. Taylor recalls the circumstance: .

So, if I was talking online with someone at S. D. C., and I wanted to talk to someone I knew at Berkeley, or M. I. T., about this, I had to get up from the S. D. C. That idea is the ARPANET. Most computer science companies regarded the ARPA. At year's end, ARPA considered only two contractors, and awarded the contract to build the network to BBN Technologies on 7 April 1. The initial, seven- person BBN team were much aided by the technical specificity of their response to the ARPA RFQ, and thus quickly produced the first working system.
This team was led by Frank Heart. The BBN- proposed network closely followed Taylor's ARPA plan: a network composed of small computers called Interface Message Processors (or IMPs), similar to the later concept of routers, that functioned as gateways interconnecting local resources. At each site, the IMPs performed store- and- forward packet switching functions, and were interconnected with leased lines via telecommunication data sets (modems), with initial data rates of 5. The host computers were connected to the IMPs via custom serial communication interfaces. The system, including the hardware and the packet switching software, was designed and installed in nine months. In addition to the front- panel lamps, the DDP- 5.
