Tends to be more localized and less visible in many cases.

Iâ??m aware of at least one regional network that has duplicate packet issues going on and theyâ??ve yet to understand the root cause.  This can have performance impacts that are not always understood.

Things get harder to diagnose when thereâ??s multiple paths, etc.. involved.  Many folks these days just fail away from a seemingly problematic link quickly and donâ??t always identify the root cause.
