I'm a bit surprised at the frequency at which people who claim to be
networking protocol engineers fail to appreciate the benefits of clean
separation-of-function and layering.
Hopefully the drawbacks are appreciated also. Quoting Rich Seifert,
"Layering makes a good servant, but a poor master. Use layering to
organize the way you THINK about networks, but don't let it restrict how
you DESIGN networks." If I recall correctly, David Clark used to say
something very similiar to this in a protocol workshop class at Interop
awhile back.
