NAP/ISP Saturation WAS: Re: Exchanges that matter...

The GIGAswitch has theoretical difficulties. Head of line blocking and so
on. But the exchanges that use GIGAswitches aren't having measurable
problems which are traceable to the GIGAswitches. The "O" in NANOG is for
"operations" and in the field of operations, anything that works gets used.

There is a conclusion to be drawn from this regarding ATM.
