  • Patent number: 6928475
    Abstract: A method of determining a connection between a data emitting device j having address IP(j) and a data receiving device i having address IP(i) via a routing device, wherein the routing device utilizes a management information database MIB, establishing a mask field in the MIB for all devices in a subnet which passes data through the routing device having a property (IP(i) AND MASK)=(IP(j) AND MASK), and indicating connection of a device i to a device j for devices in which the property is true.

  • Patent number: 6829641
    Abstract: A method of determining a connection between a data emitting device and a network device which may carry the data, wherein the network device is comprised of a store for a data source address of a last frame transmitted to the network device and an input traffic count comprising: (a) periodically reading the data source address, (b) periodically reading the input traffic count, (c) determining whether the data source address has always stayed the same, (d) in the event the data source address has always stayed the same, determine whether the traffic count has exceeded a predetermined threshold, (e) in the event the result of step (d) is true, indicate that the data source address identifies with acceptable probability a data emitting device directly connected to the network device.

  • Patent number: 6728670
    Abstract: 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 network by sensing a sequence of reception of the signal in the devices from the source device toward the destination device.

  • Patent number: 6046988
    Abstract: A method of determining network topologies comprising monitoring traffic received by devices connected in the network and traffic emitted out of the devices, correlating traffic out of the devices with traffic into the devices, indicating a network communication path between a pair of the devices in the event that the correlation of traffic out of one of the pair of the devices and into another of the pair of the devices is in excess of a predetermined threshold.
