Matthias,
I'm not sure if my email address is accepted by the IH list.  If not, 
will you please forward this message to the list.  See my notes below 
your notes below.

      According to my research ca. one year ago, there are a host of prior
      papers essentially anticipating in full the point made in the 1977
      Davidson et al paper.

The following is not intended to add substance to the current 
discussion of laying on the IH list -- just to give a tiny personal 
note.  The full reference to Walden, 1975 is "Host-to-Host 
Protocols," International Computer State of the Art Report No. 
24:  Network Systems and Software, Infotech, Maidenhead, England, 
published 1975, pp. 287-316; reprinted in A Practical View 
of  Computer Communication Protocols, J.M. McQuillan and V.G. Cerf, 
IEEE, 1978, pp. 172-204.

Lyman Chapin told me at the time of his book with David Piscitello 
(Open Systems Networking) that my 1975 paper was the first 
(published?) instance he had found of that protocol layers figure. 
That sort of surprised me as at the time the idea of layering had 
been around (in my memory) since nearly the beginning, and my memory 
was that we used that figure rather widely.  I do believe (although 
old memories can be faulty) that I in fact was the person who first 
drew that *particular version* of the laying figure to illustrate how 
it seemed to me that the layers went together and that there was some 
skipping around layers. I'm not sure if I drew it for the 1975 
conference or earlier for some technical report to ARPA or other 
informal note, and surely it was based on common knowledge at the time.

If the 1977 Davidson paper being mentioned is our six-author paper on 
TELNET, the history there is that I conceived of the paper and asked 
the other authors to participate, and Bob Thomas and I did the 
integration of the individual parts with the paper passed around for 
review as is normal for collaborative writing projects.  The author 
order is of course alphabetical.  Including the layers figure in 
there was surely my idea.
