On the inverse, routers--if designed properly, can be 10 times better
because of lower overhead, cost effectiveness, etc.  I don't think this
is going to be a debate that one will win in this forum.  There are
many router only based backbones, such as ours, Digex, etc.  Then there
are the many on the fr/router side..  just as "effective" one might
say..

This is not exactly true. Frame Relay -- if designed properly, and with
good frame switches -- can be - IMHO - 10's of times better. 

Frame Relay allows yout he ability to psuedo-directly connection various
pop's together, and gives that clean appearance of a 'no-hop' back bone. 
Why route when you can switch?

I've noticed that several of the larger networks use frame-relay.

Why? Our experience with frame-relay with the local telco has had
mixed results.

What technical advantages does a frame-relay network have over an 
IP routed network?

Thanks!
