ABSTRACT:
In one embodiment, an endpoint sends messages containing Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (NATs) (STUN) requests to traceroute a path to the remote endpoint. The traceroute may be completed through security devices such as NATs and firewalls. Receipt of a STUN response from the remote endpoint signals that one of the traceroute packets reached the remote endpoint whereas the other traceroute packets have elicited error responses from intermediary, on-path routers, allowing these routers to be identified.
