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.
