I'm experiencing network lags. I know this from ping, but I would want to know what hop/node is causing the issue so I can fix it (or at least I know who to blame). How I could I check the latency between hops?

(Any tool should be preferable OS independent)

There are tools for almost any OS that do traceroute or tracepath. The problem with them is interpreting the information correctly and there seems to be a problem in it's usage. For Unix-like and Windows there's MTR and WinMTR. It does everything that you expect from a traceroute tool.

From unix/linux using:

mtr somehost.com

Will launch a GUI if available and display hop number, the packet loss percentage (this one is critical), amount of package sent, the last packet time response (similar to ping), an average/median, minimum and maximum response time.

From Windows, just download the zip file, extract it then run it. It will present you a box where you can type the host that you want to test against the interpretation is the same as Unix version.

  • Any packet loss is a bit of a disaster so it should be 0 or just an occasional 1. The kicker for VoIP and games is latency. So the round trip time is key. However, on a tracert, you can expect MOST of the hops to have 100% loss as they wont respond to the ICMP packets for security reasons. The display above indicates some serious network issues!
