The problem is that the TCP/IP model stops at level 4, and if we consider TCP a protocol of transport, it shouldn't do that.
In the OSI model what you talk about is level 5, that is session, but in TCP/IP there is no such level, thus it must be handled by the application (e.g. trough a session cookie, in HTTP).
- klysm 2y agoI disagree. There’s no reason TCP couldn’t work like that. See QUIC for example
- wmf 2y agoSlavish adherence to theoretical models is a recipe for failure. Even worse, the OSI model was developed in the 1970s before successful internetworks existed so it's not informed by experience; it's mostly made up.
