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.
Is it the concensus of this group that the "GIGAswitches aren't having
measurable problems"? I have recently received messages from the "Operators"
at MAE-West that don't seem to support this position.
There is a conclusion to be drawn from this regarding ATM.
I run an IP/ATM network with which I am happy. Most NSPs either use ATM
for transport or are rumored to be moving in that direction.
