It becomes a packet shredder when it doesn't do EPD/PPD, dropping a
small percentage of cells on overload but a large percentage of
packets. You have to overprovision to start with.
Also in the "dead horse dept" (I hope) unless you are dealing with
boneheaded switch vendors. Some don't believe in EPD/PPD preferring
ABR. Are any of them still entirely clueless in this regard and not
doing either EPD/PPD or ABR?
