The fault tolerance of FDDI and the build quality of DEC's gigaswitch products. The bandwidth of FDDI is a lot better than fast ethernet. Not true, not unless the implementation is crummy. Any halfway decent fast Ethernet host will run at wire speed, and the difference between 1500 and 4460 MTU isn't enough to amount to very much. Except for the fact that on ethernet you took the framing hit to your speed (100Mbps link level) and with FDDI the framing was done outside of your "speed" (125Mbps link level, true 100Mbps data). -brian
