The RAND group had written a paper on packet switching networks for secure voice in the military in 1964.
It happened that the work at MIT (1961-1967), at RAND (1962-1965), and at NPL (1964-1967) had all proceeded in parallel without any of the researchers knowing about the other work.
Kleinrock’s conviction of the need for packet switching was confirmed.
In late 1966 Roberts went to DARPA to develop the computer network concept and quickly put together his plan for the “ARPANET”, publishing it in 1967.
Today, terms like “[email protected]” and “ trip lightly off the tongue of the random person on the street.
This is intended to be a brief, necessarily cursory and incomplete history.
At the conference where he presented the paper, there was also a paper on a packet network concept from the UK by Donald Davies and Roger Scantlebury of NPL.
Scantlebury told Roberts about the NPL work as well as that of Paul Baran and others at RAND.
to the Q-32 in California with a low speed dial-up telephone line creating the first (however small) wide-area computer network ever built.
The result of this experiment was the realization that the time-shared computers could work well together, running programs and retrieving data as necessary on the remote machine, but that the circuit switched telephone system was totally inadequate for the job.
