Well, also keep in mind that pure ATM/FR is becoming more and more of an edge service, where it is actually transported as MPLS in the core. Thus, an MPLS VPN does make more sense in some cases (why would I want to take a beating on cell tax if I don't have to?)

And being replaced with ....  ?  GigE?  DPT/RPR?  MPLS?

ATM is a great technology...  Unfortunately, I don't think it was ever
fully utilized..  From what I understand, MPLS takes some of the good
bits and combines it with traditional routing..  But I don't see a lot
of MPLS implementations either...
