It's difficult to remember clearly from 25 years ago, the OSI model was certainly covered, and I clearly remember datagram programming, but nothing in terms of say network routing protocols.
The engineering course covered token ring. Remember in 2000, and certainly a few years before (when I suspect half the courses were created as lecturers often go years between updating them), Ethernet and IP were not the only kid on the block. Netbios/ipx was still in widespread use, Token ring (which I do remember being covered, as I'd encountered ipx and ip over serial and ethernet, but never token ring) was still being developed. HTTP was only 9 years old.
