Followup: In the message from Grenville Armitage referred to above: - #1 refers to forwarding based on caching the forwarding information. It is not particularly relevant to today's *ASIC* based forwarding engines. I believe it's not particularly relevant to CPU based forwarding either: You would not *use* such a router precisely because performance would be abysmal. - #2 refers to forwarding based on an ATM cell fabric. This, too, is not particularly relevant today. So, my basic claim is that the world has moved on, and claims made in 1997 about an MPLS forwarding speed advantage simply aren't relevant today.
