  • Patent number: 10805408
    Abstract: A system and method for discovering Internet Protocol (IP) network address and port translation bindings is disclosed. According to one embodiment, a system for creating IP data records, includes a carrier grade network address and port translation (CGNAPT) node in communication with a private network on an internal side and a public network on an external side. The system further includes a private Ethernet span port disposed on the internal side of the CGNAPT node that receives packet streams traversing the CGNAPT node. A public Ethernet span port is disposed on the external side of the CGNAPT node that receives packet streams traversing the CGNAPT node. The private Ethernet span port and the public Ethernet span port copy packet streams traversing the CGNAPT node and deliver the copied packet streams to a deep packet inspection host.

  • Patent number: 6624750
    Abstract: A wireless alarm system (10) employs two-way transceivers (32, 60) in a network of smoke detectors (16), a base station (12), and other sensors. A keypad (14) is not needed because the system is reset by pressing a Test/Silence button (66) built into every detector or sensor. A siren is also eliminated because a sounder (64) in every detector sounds an alarm when any sensor is triggered. This is possible because every detector includes a transceiver that can receive alarm messages from any other detector. AC power wiring is also eliminated because the base station and sensors are battery powered. Only a telephone connection (48) is needed if the system is to be monitored. In apartments or dormitory installations, smoke detectors in one apartment relay alarm messages to the next apartment, and onto the next, and so on, to a centralized base station for the entire facility.
