I have an interesting problem: I need some host that doesn't mind being pinged but with several seconds of RTT (that's thousands milliseconds; from Moscow, but it probably doesn't matter).
Just something to keep in mind, if they have such a terrible network connection, they probably would not appreciate being pinged (if you mean continuously or at any degree of regularity), chipping away at their miniscule network bandwidth in favor of some random person's unrelated research...
My experience is it’s not always about the lack of connectivity, it’s about odd buffering behaviors of devices. The Juniper M40 would buffer an incredible amount of data on the FPC for a T1 speed link whereas a OC48 FPC had the same buffer sizes for much higher rates. Of course, this all assumes you know what you’re measuring, which is a critical part of it. - Jared
