Adaptive tracing with a reduced number of probes to avoid firewall issues

Abstract:

Techniques for using trace with tunnels and cloud-based systems for determining measures of network performance are presented. Systems and methods include determining a number of hops from a source that is the user device and a destination, including determining metrics from the source to the destination; performing a trace to all intermediate nodes between the source and the destination, including determining metrics from the source to each of the intermediate nodes; and combining and presenting the metrics from the source to the destination and from the source to each of the intermediate nodes.
