Yes, if you're an IPX network...
With TCP/IP you have something called windows and ICMP source quencing.
With UDP/IP you can flood a 100Mb full duplex link.
Turning on full duplex, in most TCP/IP environments, FAR outweighs the
alternative; collisions.
All this is mostly irrelevant. If your network is designed right, you're
not pushing a 100Mb network at a full 100Mb. You've added ATM, giga
ethernet, or load balanced over multiple links.
