Richard Steenbergen has released excellent slides and a technical document on Traceroute from a presentation he gave at a networking conference.
You can see the slides here. Most people will find that they’re the easiest to follow. However, those that wan’t to dive a bit deeper into the technical networking details, you can also read his document here.
If you’re an IT Manager trying to troubleshoot latency across your network, or a web developer trying to figure out why your web server is acting so slow all of a sudden, and every in between, you’ll find this document worth the read. It’s also a great overview for a beginner.
