Old articles about TCP/IP

[Retro1234]

Looking for some old articles on TCP/IP something that might of appeared in Amiga Format "You've all heard of TCP/IP but what is it" something like that.

Not just Amiga stuff but any retro old PC stuff or any other format.

I'm not looking for modern guides etc I know all about TCP/IP. I'm looking for old articles etc - for retro articles talking about it.

One of the amiga magazines came with demon.co.uk floppy disk with AmigaTCP which had instructions on how to download AmiTCP/IP and set up the browser, ftp client, IRC client and some info about TCP/IP.

Is that what you wanted?

[Retro1234]

Sounds interesting.

What i'm thinking is now we take TCP/IP suite for granted. It comes built into the OS.
I'm think some article of what is this revolutionary thing and why do you want it etc.

Something like that?

Funny that the article calls it ip/tcp. I actually find that more logical. IP over TCP.

Trumpet Winsock was the popular package in Windows 3 days, I bet some of the old documentation would be the kind of thing you want.

First Steps Amiga Surfin' by Karl Jeacle (of AmiGemini fame) and Dale L. Larson's Connect Your Amiga are probably worth a look. Both are available at https://commodore.bombjack.org/amiga/amiga-books.htm

Thanks everyone

@Nightshift yep just like that

@Gimbal yeah I noticed that but it's only the once but makes you wonder.

@aeberbach Thanks dude I'll check it out.

@stevelord haven't checked yet but sounds just the kind of thing.p
: Just looked,that is great also the stuff on PPP have to admit I don't fully get PPP so anything on PPP is also great

The use of the word over can be confusing.. ;-)
But I agree, IP/TCP is much more accurate.
TCP, UDP, ICMP, 54, etc all run within IP.
So IP is the top, over the others.
That said, "IP over TCP," while an accurate description of the visual, makes it sound like IP is running on top of (over) TCP, which is the opposite of what is happening. ;-)
So it is both accurate and the opposite of accurate.
Gotta love grammar!!! ;-)

TCP/IP doesn't "stand for TCP over IP", it stands for "Transmission Control Protocol/Internet Protocol". The "/" doesn't mean "over" and is more like "and".

It is purely the name of the suite of protocols with IP being the underlying network routing protocol.


In terms of which protocol sits over another, the OSI 7-layer model defines how things work https://en.wikipedia.org/wiki/OSI_model with each layer sitting on top of the previous layer and building upon it, each time getting a higher level and closer to the user and abstracting away from the physical hardware.


This starts at the bottom with the "physical" layer (layer 1)

This is followed by the "data link" layer (layer 2)

IP or Internet Protocol sits above this at the "network" layer (layer 3)

TCP sits above this in the stack at the "transport" layer (layer 4)

Above this, you have the application centric layers "Session" (5), "Presentation" (6) and "Application" (7). Whilst the OSI 7-layer model lists these separately, it's not uncommon to see these bundled together as the lines between them can be quite blurred. These are the highest levels and are closest to the user.


You wouldn't say "IP runs over my web browser" (layer 3 runs over layer 7) and in fact say "my web browser runs over IP" (layer 7 runs over layer 3), so why would it be correct to say "IP runs over TCP" (layer 3 runs over layer 4)?


You can follow the same analogy with, for example, a railway - the tracks are layer 1, followed by the wheel section (bogies at layer 2) followed by the chassis (layer 3), followed by the carriage (layer 4), followed by the seats (layer 5). Instead of a carriage at layer 4 you could have a gravel hopper or a liquid container, the underlying layers are the same, but the user interface layer has changed for a different purpose... and the tracks don't run over the carriage, the carriage runs over the tracks

yes but nobody was talking about that, we were talking about the odd way of flipping it around. So... wasted opportunity of throwing the book at people I'm afraid.

To be honest - exactly the kind of post I was trying to avoid.

I've clearly hit a nerve, for which I apologise, as there was no intent.

My post was purely one of education explaining how the various layers work and how/why it is called TCP/IP. The reference provided was for further reference. It wasn't the case of "throwing the book at anybody".
