>the excessive overhead present in FDDI networks...FDDI is not a WAN technology. Losing 20% of bandwidth of a 10 ft
piece of fiber is one thing. Losing 20% of bandwidth of a
$3M/yr circuit is quite different.ATM as a LAN is probably ok, if it can compete with Gb Ethernet
price/performance-wise.
In the smaller networks, GigabitE may well turn out cheaper than ATM,
but Ethernet will never have the design flexibility ATM does.
...and any technology which experiences performance problems at 40%
utilization will is questionable at best...
