Abstract
Techniques for using traceroute with tunnels and cloud-based systems for determining measures of network performance are presented. Systems and methods include receiving a request, from a client, for one or more of a first trace of a tunnel and a second trace to a destination; checking a cache at the node for results from previous traces of the first trace and the second trace; responsive to the results not being in the cache, performing one or more of the first trace and the second trace; and providing the results to the client so that the client aggregates the results with details from one or more additional legs to provide an overall view of a service path between the client and the destination.
