Abstract
Techniques for using traceroute with tunnels and cloud-based systems for determining measures of network performance are presented. Systems and methods include requesting a trace to a destination with a signature inserted into a trace packet; receiving a response to the trace packet; when the response does not include tunnel info, providing details in the response to a service where the details include parameters associated with a service path between the client and the destination; and, when the response includes tunnel info, segmenting the service path into a plurality of legs, causing a trace for each of the plurality of legs, and aggregating details for each of the plurality of legs based on the causing.
