Detection of latency, packet drops, and network hops through a TCP tunnel using ICMP and UDP probes

摘要

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 to perform a reverse trace; requesting a trace to an endpoint that is one of an egress router and a tunnel client, wherein there is a tunnel between i) the destination and ii) the one of the egress router and the tunnel client; receiving a response to the trace; and sending details associated with the response to the client so that the client aggregates these details with details from one or more additional legs to provide an overall view of a service path between the client and the destination.
