In 1964 a researcher at the Rand Corp. named
Paul Baran came up with a bizarre solution to this Strangelovian puzzle. He designed a computer-communications network that had no hub, no central switching station, no governing authority, and that assumed that the links connecting any city to any other were totally unreliable. Baran's system was the antithesis of the orderly, efflcient phone network; it was more like an electronic post offlce designed by a madman. In Baran's scheme, each message was cut into tiny strips and stuffed into electronic envelopes, called packets, each marked with the address of the sender and the intended receiver. The packets were then released like so much
confetti into the web of interconnected computers, where they were tossed back and forth over high-speed wires in the general direction of their destination and reassembled when they finally got there. If any packets were missing or mangled (and it was assumed that some would be), it was no big deal; they were simply re-sent.
