<div>Anyone with an SC16 archive should have them. I believe I
have the first 300 or so documents on Microfiche somewhere. You
are looking for SC16/N46, N117 and N227. These were the outputs
of the Washington, 78 meeting; Paris, Oct 78; and London, 79;
respectively. The DP version should also be around which would
be Berlin 1980. The document went through a complete
re-organization between 117 and 227. The Babbage Institute has
the proto-version of that document.</div>

received the figures for his RFC 871 (1982). His figures are an
interesting half circular representation of the three layer Arpanet
model, which he adapted from an earlier Davidson/Postel paper (see
below). I'd be interested to see if the Cohen/Postel paper
above also has a version of the half-circle diagram.</blockquote>

<div>Layering did not originate with the OSI model. The model
really just wrote down what people were thinking at the time.
There had been talk of these layers all through the 70s.</div>

<div>Further questions on the OSI stuff let me know.</div>
