ABSTRACT:
A method for tracing a communication route through a network coupling a first device with a second device is provided. A first signal is transferred from the first device to the second device to cause a plurality of intermediate devices to report first information concerning the first signal. The first information is processed to identify the intermediate devices as defining the communication route. The intermediate devices are configured so that a second signal, when transferred from the first device toward the second device, causes a subset of the intermediate devices to report second information concerning the second signal. The second signal is transferred from the first device toward the second device. The second information is processed to identify the subset of the intermediate devices as a portion of a sequence of the intermediate devices defining the communication route.
