Abstract
In one embodiment, the integrity of forwarding paths within a packet switching device is investigated. A packet switching device creates a probe packet. The packet switching device then communicates the probe packet within the packet switching device in a normal forwarding manner, while monitoring at multiple positions along forwarding paths through the packet switching device for the appearance of the probe packet. The traveling within the packet switching device of the probe packet, including as identified by the monitored positions, is analyzed to identify whether or not the probe packet was correctly forwarded at one or more locations within the packet switching device.
