hence this fddi is at 90%: why not add another onte? It is bridged anyways.

Maybe because they want people to pay the difference to upgrade...

Maybe because inside a DEC GIGAswitch, there's an 800Mb/s crossbar switch such that while the peak b/w between any pair of ports is limited by FDDI's spec (100Mb/s, or 200Mb/s full duplex), the peak b/w between all pairs of ports is limited to a much higher number (800Mb/s.) Thus Andrew's comment earlier about the MAE-East GIGAswitch humming along nicely at 190Mb/s peak load. The shared FDDI can't do that, and a bridge between two shared FDDI's couldn't do that. DEC did something wonderful with that GIGAswitch, it would behoove you both to understand what it was in case you need similar technology inside your own hubs. Not to mention the importance of choosing the right way to connect at a MAE or NAP, and especially not to mention the importance of knowing which side of the MAE-W T3 you want to be on. (As long as I'm singing the GIGAswitch's praises, I'd like to add that DEC is planning a GIGAswitch-to-GIGAswitch interconnect product but it will only run at a few hundred megabits, not the full b/w of the crossbar; and further, they now sell an ATM version of the GIGAswitch in case you don't want FDDI but you need an ATM with working congestion control.)
