ARPANET pristupne tačke 1970-ih

Advanced Research Projects Agency Network, u prijevodu Mreža agencija za napredne istraživačke projekte (ARPANET) bila je prva mreža sa komutacijom paketa širokog područja sa distribuiranom kontrolom i jedna od prvih mreža koja je implementirala paket TCP/IP protokola. Obje tehnologije postale su tehnički temelj Interneta. ARPANET je osnovala Agencija za napredne istraživačke projekte (ARPA) Ministarstva odbrane Sjedinjenih Država.[1]

Nadovezujući se na ideje J. C. R. Licklidera, Bob Taylor je 1966. godine pokrenuo projekat ARPANET kako bi omogućio dijeljenje resursa između udaljenih računara.[2] Taylor je imenovao Larryja Robertsa za menadžera programa. Roberts je donio ključne odluke o dizajnu mreže.[3] Ugradio je koncepte i dizajne Donalda Daviesa za komutaciju paketa,[4] [5] i zatražio pomoć od Paula Barana.[6] ARPA je dodijelila ugovor za izgradnju mreže Boltu Beranek & Newmanu koji su razvili prvi protokol za mrežu. [7] Roberts je angažovao Leonarda Kleinrocka na UCLA da razvije matematičke metode za analizu tehnologije paketne mreže.[6]

Prvi računari su povezani 1969. godine, a protokol mrežne kontrole implementiran je 1970.[8] [9] Mreža je proglašena operativnom 1971. godine. Dalji razvoj softvera omogućio je udaljenu prijavu, prijenos datoteka i e-mail.[10] Mreža se brzo širila i operativna kontrola je 1975. prešla na Agenciju za obrambene komunikacije.

Mr. Taylor wrote a white paper in 1968, a year before the network was created, with another ARPA research director, J. C. R. Licklider. The paper, "The Computer as a Communications Device," was one of the first clear statements about the potential of a computer network.

He decided to use packet switching as the underlying technology of the Arpanet; it remains central to the function of the internet. And it was Dr. Roberts's decision to build a network that distributed control of the network across multiple computers. Distributed networking remains another foundation of today's internet.

In 1965, Davies pioneered new concepts for computer communications in a form to which he gave the name "packet switching." ... The design of the ARPA network (ArpaNet) was entirely changed to adopt this technique.

The Internet was born of a big idea: Messages could be chopped into chunks, sent through a network in a series of transmissions, then reassembled by destination computers quickly and efficiently. Historians credit seminal insights to Welsh scientist Donald W. Davies and American engineer Paul Baran. ... The most important institutional force ... was the Pentagon's Advanced Research Projects Agency (ARPA) ... as ARPA began work on a groundbreaking computer network, the agency recruited scientists affiliated with the nation's top universities.

Roberts recruited Baran to advise the ARPANET planning group on distributed communications and packet switching. ... Roberts awarded a contract to Leonard Kleinrock of UCLA to create theoretical models of the network and to analyze its actual performance.
