The OSI stack can encapsulate all forms of agreement between parties over a network; if you've got a protocol, it has a place in the OSI stack. Not that I think the OSI model is the be all and end all of stacks (I don't), but it is complete in that sense. The IETF model is similarly complete. (and BTW, "network layer", in this context, usually refers to OSI layer three) We've had this discussion here, in other forms (i.e. "GET is an application semantic"), so I don't expect us to come to any agreement about this. If there's concensus in the WG about what you've written, I would request that this be reflected in the arch doc so that IETFers and other OSI/IETF model folks can be aware of the difference in terminology. Or perhaps it could just go in the glossary, in the definitions of "application layer", "transport layer", etc.. MB -- Mark Baker.
