I'm learning networking troubleshooting and noticed how there are three different time values outputted for every hop when using traceroute, what do they mean? (The left CLI in the image is a router and the right is a Windows CLI)

Three requests are made for each hop, and the times represent the round-trip time for each request. In your first example, the third request to hop number 3 took far longer than the other two.

You're likely to see bigger disparities for more distant hops as there are more factors that can affect round-trip times.

  • Ahaa! Do you BTW know any flag or something you can use together with traceoroute/tracert to at the end of the output get min/avg/max times? @flup

  • I don't, but stats like that would be pretty meaningless. You might be better off looking at the stats at the end of a ping run.

  • Of course, I just got them mixed up ;) @flup

  • If you want something with more stats than traceroute, look at MTR: en.wikipedia.org/wiki/MTR_%28software%29
