The paper, "The Design Philosophy of the DARPA Internet Protocols", was
written by David Clark in 1988. Mr. Clark clearly describes the 8 original
design goals for the Internet protocol and how their relative priorities led
to certain design choices. This includes the use of a layered architecture
and routing using stateless packet switching. While the author does credit
the ubiquity of Internet protocol adoption to the datagram and the limited
demands it makes of the networks that support it, he does suggest that some
sense of "flow" may need to be adopted in the next generation in order to
more adequately address a number of the original design goals. Perhaps the
most startling aspect of this paper is the insight of how little statistical
understanding through modeling tools or simulations the designers of the
Internet really had in structuring its protocols. Their success is truly an
engineering marvel.
