Question Karon:
With most routers intentionally designed to answer packets destined for themselves at a considerably lower priority (lower than lowest? ) than packets going through them... how does pingplotter help with that?
This is often the reason why, when you graphically plot pings, you will find that places in the middle can take longer than getting to the destination. This, of course, should make you doubt the results in the middle, since logically the sum of the whole will always be greater than the sum of a half. As a result, fluctuation of the RTT in the middle should be dismissed as misleading information.
