Dear Hannes, absolut correct, we act in the past and on the level of the past. In this time, the digital information, coded in analog signals, was going over a pure analog system with relais and amplifiers and on the end you have the digital information decoded. In general, nature does not know digital technology. Data transmission will always be analog. Internally in our data processing systems we work with digital interpretation of analog signals. In analog systems, no error checking can take place that relates to digital interpretations. But today, every node in the network works with digital information. Only the connections must still be analog. And thus the error checking can take place in each segment of the transport system. TCP/IP is no longer needed. Also, because the resources in all end nodes are sufficient to receive the packets. If not, the transmitter can determine the capacity of the receiver beforehand, or the receiver will reject the reception. greetings, willi Am 16.03.2022 um 04:49 schrieb Hannes Tschofenig: > 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.

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. > > Ciao > Hannes > > IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
