ABSTRACT:
Nodes in an Internet Protocol (IP) network receive probe packets configured to travel over particular IP media paths. The probe packets cause the network nodes to send media path reports to a logging system. The media path reports contain information identifying the different nodes in the media path. The logging system can reconstruct the network topology of a particular media path from the media path reports which can then be used for debugging purposes. In one embodiment the probe packets are Resource Reservation Setup Protocol (RSVP) packets configured for media path probing.
