What kind of interface do you want ? You have async (multiport async), sync, ethernet, fddi and now atm is coming. BTW, do you get arcnet with cisco ? :-)

HSSI?

ATM is doable today. There are multiple HSSI vendors out there: http://www.lanmedia.com/products.htm http://www.sdlcomm.com/

Define lots. You want full BGP table in a PC router ? Why :) ?

The bandwidth through a router is not necessarily directly related to the amount of routing information that one needs to support. For example, one can easily imagine a multi-homed site that buys transit from multiple backbones. While no single backbone is deserving of very high bandwidth, the need to maintain a full routing table for optimal return path routing could be quite high. Tony
