Abstract
Techniques for tracing routes taken by data packets transmitted through an overlay network are disclosed. A system uses a first TTL value for selecting a number of hops in an underlay network and a second TTL value for selecting the number of hops in the overlay network. Initially, the system increments the first TTL value with each new probe packet while holding the second TTL value at zero or one. When an overlay network node is reached by one of the probe packets, the system increments the second TTL value with each new probe packet. While incrementing the second TTL, the system holds the first TTL value at a constant value higher than the first TTL value corresponding to when the overlay network node was reached.
