ATM

Wed Jun 29 17:34:28 UTC 2005

Most MPLS networks use a combination of point to point, frame and ATM
facilities as the infrastructure.  The phone companies use ATM just
about everywhere to deliver voice across their networks.  I don't see
ATM/FR equipment being EOL'd anytime in the near future.

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!"
