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?) -Jeff -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Jason Frisvold Sent: Wednesday, June 29, 2005 10:19 AM To: Petri Helenius Cc: Philip Lavine; nanog Subject: Re: ATM On 6/29/05, Petri Helenius <pete@he.iki.fi> wrote:

Maybe the small fact that ATM is fading away and building new networks with technology going away is going to explode your operational cost in a few years time. Business grade IP networks will provide you with equal if not better performance than a "dedicated" ATM WAN.

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...
