Posted by on August 16, 2013

When manually diagnosing network performance issues, there are several techniques that can rely on ICMP probing, e.g. measuring round trip time, measuring end-to-end loss, tracerouting, etc. In this article we will show that ICMP introduces some bias in these measurements, and that by using TCP-based probing we are able to overcome most of the limitations of ICMP.… Read More »
