Technorati Profile

The system of communications that
Baran attacked in the early 1960s at RAND was the imperial establishment
of AT&T. As Baran explains, "While AT&T did have digital
transmission under examination, it was in the context of fitting
directly into the plant by replacing existing units on a one-for-one
basis. A digital repeater unit would replace an analog loading coil. A
digital multiplexer would replace an analog channel bankalways a
one-for-one conceptual replacement, never a drastic change of basic
architecture. I think that AT&T's views on digital networks were
most honestly summarized by AT&T's Joern Ostermann after an
exasperating session with me: 'First, it can't possibly work, and if it
did, damned if we are going to allow the creation of a competitor to
ourselves.'"
In 1972 the company sealed its fate by turning down an opportunity to
buy the entire Arpanet. As Larry Roberts explained in Where Wizards Stay
Up Late, "They finally concluded that the packet technology was
incompatible with the AT&T network." So it was and so it still is.
The existing phone system remains the chief obstacle to the final
triumph of the Net. But the logic of digital communications is
inexorable. It will displace all the existing establishments of
television and telephony.
