In January, the ARPANET standardizes on the TCP/IP protocols adopted by the Department of Defense (DOD). The Defense Communications Agency decides to split the network into a public ‘ARPANET’ and a classified ‘MILNET, ‘ with only 45 hosts remaining on the ARPANET. Jon Postel issues an RFC assigning numbers to the various interconnected nets. Barry Leiner takes Vint Cerf’s place at DARPA, managing the Internet. Numbering the Internet hosts and keeping tabs on the host names simply fails to scale with the growth of the Internet. In November, Jon Postel and Paul Mockapetris of USC/ISI and Craig Partridge of BBN develop the Domain Name System (DNS) and recommend the use of the now familiar user@host.domain addressing system.The number of computers connected via these hosts is much larger, and the growth is accelerating with the commercialization of Ethernet. Having incorporated TCP/IP into Berkeley Unix, Bill Joy is key to the formation of Sun Microsystems. Sun develops workstations that ship with Berkeley Unix and feature built-in networking. At the same time, the Apollo workstations ship with a special version of a token ring network. In July 1983, an NSF working group, chaired by Kent Curtis, issues a plan for ‘A National Computing Environment for Academic Research’ to remedy the problems noted in the Lax report. Congressional hearings result in advice to NSF to undertake an even more ambitious plan to make supercomputers available to US scientists. |
