A small note: > I would like to propose the following: Let's make a strict separation of transport and application. > The Internet is only a transport system for digital data in packet form and has only one task: To make sure that the packet sent by the sender arrives exactly the same at the receiver. Thus the error handling is implicit part of the transport system. Very few people use the term "Internet" to only refer to the "Internet Protocol". Instead, the Internet is usually used to refer to the whole system, including the applications, TCP/UDP, TLS, and all the other good stuff. If you narrow your definition of the "Internet" down to "IP" then your definition of the task above is wrong. IP does not provide error handling so that the packets sent by the sender arrive exactly in the same manner at the receiver. This is a function provided by layers above IP.
