To the best of my knowledge (including inquiries with colleagues) the
proverbial "3,4,5" rule for Ethernet was prior to switches, as in a
store and forward, mechanism. I think the rule was mainly to help
timing and to prevent signal degradation, which switches help take care of.
So, now, at least in theory, you could have a bridged network the world
over in one really big broadcast domain. The problem would be that it
is one really big broadcast domain which has its own down sides to
consider and mitigate.
