[Air-l] Info request re "layers" model of Internet

I think the original post by B. Lentz is asking for the defining paper for the internet layers. The question is whether you want TCP/IP model, which is 5 layers and sometimes called the DoD model, or if you want the more recent OSI 7 layer model, or some other layer definition (don't more recent IETF developments alter/supersede the layer model?). 

As I understand it, the 5-layer TCP/IP model is defined in the early 1970's at ARPA. I think the "origin" may be the following text:

Cerf, V., and R. Kahn, "A Protocol for Packet Network  Intercommunication", IEEE Transactions on Communications, Vol. COM-22, No. 5, pp 637-648, May 1974.

Certainly Vint Cerf was the co-author. I would start there.

As to OSI, I would look here: http://www.comsoc.org/livepubs/50_journals/pdf/RightsManagement_eid=136833.pdf

Not sure whether you were referring to this, but Yochai Benkler also referenced
a model of layers to explain the architecture of the internet.
Different from the OSI layer model, he instead talks about a Physical,
Logical and Content layer.
