Paul Baran
Larry Roberts convenes a conference in Ann Arbor, Michigan, to bring the ARPA researchers together. At the conclusion, Wesley Clark suggests that the network be managed by interconnected ‘Interface Message Processors’ in front of the major computers. Called IMPs, they evolve into today’s routers.
Roberts puts together his plan for the ARPANET. The separate strands of investigation begin to converge. Donald Davies, Paul Baran, and Larry Roberts become aware of each other’s work at an ACM conference where they all meet. From Davies, the word ‘packet’ is adopted and the proposed line speed in ARPANET is increased from 2.4 Kbps to 50 Kbps.
The acoustically coupled modem, invented in the early sixties, is vastly improved by John van Geen of the Stanford Research Institute (SRI). He introduces a receiver that can reliably detect bits of data amid the hiss heard over long-distance telephone connections.
