I would probably add TLS in thereas an optional layer between TCP and HTTP. But http/3 and quic complicates things because it kind of blends the tcp, tls, and http layers together.
- KirillPanov 3y agoLayer 4 is the lowest layer of the OSI model that isn't packet-based (i.e. can handle messages of arbitrary size). IMHO that's the highest layer of the OSI model that is useful. After that it's various ways of tunnelling streams inside of streams.
- fanf2 3y agoThat’s not true, though: the OSI model has connection-oriented services at the lower layers too.
