Oh, 2 things come to mind, my variability throughout an ATM cloud is greatly reduced versus a routing cloud, a cell requires WAY less time to cross a switches backplane, versus a packet through a router. And seriuosly less time to determine where to send it...
Hmm... I thought we went over this fallacy not that long ago on NANOG. Please look up the past NANOG thread with subject _Internet Backbone Index_.

Dorian, I could be wrong about a LOT of things. However, your thread in the NANOG is about network switching vs network routing, not ATM switching. This is Apples to Oranges. Network Switching: Using MAC address to determine next hop. Network Routing: Using layer three address to determine next hop. ATM Switching: A path set up once, by one or more of the above (or none), to deliver cells across a multi hop, or point, path. Although comparisons can be made between "Network Switching and Switching", they are not the same thing. (Although some elements are in common) One is a methodology to determine a path. The other is a method of delivering a requested path. Never forget, A full NxN-point Matrix (non-folded) is almost always faster than a BUS. Although, many would call a Matrix a BUS ;) Sigh..... It reminds of a local Newspaper that was so kind as to point out that Multicast is Infinitely Inferior to HDTV. And they had the GUTS to declare that Multicast would not make it because of this. Can someone point me to the multi-user conferencing specs for HDTV ? And what API set do I use to access it ? ;)
