You can't use that for measurement, on many router products the process of replying to ICMP echo's (and generating other ICMP messages) is a VERY low priority task, so if it's CPU is loaded with other tasks, you will see a excessive latency in ping's to that router, but you will probably see a much more normal delay to a host behind it. /Jesper -- Jesper Skriver, jesper(at)skriver(dot)dk - CCIE #5456 Work: Network manager @ AS3292 (Tele Danmark DataNetworks) Private: FreeBSD committer @ AS2109 (A much smaller network ;-) One Unix to rule them all, One Resolver to find them, One IP to bring them all and in the zone to bind them.
