I am not sure what the protocol model was called when I first learnt how different protocols worked over different media. To be honest, I don't think it had a name, we learnt how serial, ethernet, token ring and a number of different bus technologies worked then we learnt about Dec LAT, XNS, IP, IPX and some others. The only one I work with now is IP but when I worked for Xerox I dealt with all of them but mostly XNS. It has been 10 years since I have used anything but IP and bit of EtherTalk. I have complete left out all the non ethernet protocols. PS I found a Vampire Tap Kit a few months ago cleaning out an old desk. The "youths" I work with had no idea what it was, and when I told them how it was used, they thought I was joking. I also found an AUI cable, and showed them how networking old school was done with a couple of Cisco 2500's without using any transceivers. The had no idea that you could network machines together over ethernet with out using RJ45 patch cables. They thought I was tricking them and using a serial cable.
