Since it is probably a fair assumption that routers will never procces forwarding packets slower than ICMP replies, the following applies.On Wed, 4 May 2005, Luke Parrish wrote:
The router receiving the traceroute response from its upstream would process that in its forwarding path. So if you see a 30ms hit on hop A and a 60 ms hit on hop B you can pretty much determine that hop A is 30ms away but you cant be quite sure about hop B until you see hop C's replies.
To make this more interesting, its always possible that hop B or C's path to you is different than your path to hop B or C.
Also, traceroute is effective at showing that the path rtt is good. Its just when you are trying to find where the latency is that things can get dicey.
