A method of determining the topology of a network comprising: transmitting a signal comprised of a sequence of bursts of packets formed of orthogonal signals, monitoring devices in the network including the destination device for reception of the signal, and defining a sequence of devices within the

대표청구항 ▼

1. In a network in which signals are transmitted from a source device to a destination device, through a subset of devices having at least one device, a method of determining the topology of a network comprising: (a) transmitting a signal comprised of a sequence of bursts of packets formed of orthogonal signals from said source device toward said destination device,(b) monitoring said at least one device of said subset of devices and said destination device for reception of said signal, and(c) defining connectivity among said subset of devices, within said network, by sensing a sequence of reception of said signal through said subset of devices and in said destination device from said source device toward said destination device.2. A method as defined in claim 1 in which a pair of sequences contained in each of successive sampling periods of successive bursts are mutually orthogonal.3. A method as defined in claim 1, wherein each of said subset of devices is capable of providing means for reporting said sequence of reception of said signal.
