ARPANET was established in 1968, and the first phase of the project was put into use in 1969. At the beginning, there were only 4 nodes, and it expanded to 197 15 nodes in 0 year. After several years of successful operation, it has developed into a computer network connecting many universities, research institutes and companies throughout the United States, and can be connected with Hawaii, London and Norway in northern Europe through satellite communication, so that European users can also access the network through nodes in Britain and Norway. 1July, 975, ARPANET was handed over to the Communications Bureau of the US Department of Defense for management. To 198 1, there are 94 nodes distributed in 88 different locations. The main features of ARPANET are: ① You can enjoy hardware, software and database resources. ② Decentralized control structure is adopted. ③ Application of packet switching technology (packet switching technology). (4) Use a high-function communication processor. ⑤ Layered network protocol is adopted. These characteristics have been widely used and further developed in computer networks established in the United States and Western Europe (such as European information network EIN, CYCLADES in France, TYMNET, CYBERNET, TELENET, AUTODIN2 in the United States, etc.). ).
Its leader is Roberts, known as the father of ARPANET.
Father of ARPANET: Larry Roberts
Arpa in Arpa (ARPA- transliteration) The original meaning of com is the American Advanced Research Program.
Larry Roberts was born in 1938. His parents are chemists at Yale University. He studied at MIT, from bachelor's degree to master's degree until he got his doctorate. After entering the computer field by self-study, I have made extraordinary achievements in software design, computer drawing, especially communication technology, and have brilliant organizational and management capabilities.
From 65438 to 0967, Larry Roberts joined ARPA and was responsible for the design, planning and development of ARPA network.
Roberts later recalled that he was basically "blackmailed" by Taylor and forced to work in ARPA. Because he didn't want to leave Lincoln Lab, after many entreaties, Taylor had to use administrative means to force him to take office, which made him mistakenly call himself "the father of ARPANET".
After 1973, he left ARPA and served as the chairman and CEO of several Internet companies for many years.
After 1999, he served as chairman and technical director of Packetcom.
Larry Roberts won many honors in his life, including the Meritorious Service Award of the US Department of Defense, the Computer Pioneer Award of the Institute of Electrical and Electronics Engineers (IEEE) and the Data Communication Award of the American Computer Society.
