You can get info at:
The Gigaswitch/FDDI is a different product than the Gigaswitch/ATM. You
can insert ATM uplinks into the Gigaswitch/FDDI.
I won't discount Gigabit Ethernet to quickly (yet there are no router
interface available). I believe Ether Channel has an opportunity depending
on what happens with the GSR but there is no switch to take advantage of it
(except maybe the Cat 5500). But I do agree that traffic shaping
technology is critical to any long term design. I guess the ideal solution
will be Gigabit Ether Channel (8Gbps) or Terrabit Ethernet with traffic
shaping if its not ATM at OC-192.
