Guys,

ATM as a desktop technology is dead. period.

ATM as a core technology has no merit at speeds above OC3. The cell tax easily exceeds 15%. There is a reason that Cisco and Juniper rule the core of ISP's - they do packet over sonet. The competition only did packet over atm and missed the boat.

Where does it fit - service provider carrier networks providing low speed (DS0 to DS1) connectivity to large enterprises with branch operations. As the underlying technology for DSL access and in similar environments.

As to the vaunted QOS properties of ATM - most commercial services do not provide them. You are lucky to get congestion notification on many provider networks.

In the lab and on paper ATM shines. In the real world its relegated to a niche. Yes this niche is growing, but don't read too much into it.
