look to the private networks luke... Seriously, many large private
ATM/Frame networks are transitioning to MPLS networks because the ATM or
Frame gear is/was/will-be-shortly EOL/EOS from the vendors. The costs to
run these networks don't jibe well with the alternatives.
Now, start the discussion on: "private network" and "mpls vpn" and "oops,
hey, that runs over the same routers as that bad-old Internet thing with
the haxors and such!"
