  • Patent number: 12126545
    Abstract: Provided is a communication device that operates as a management node in a first zone being a management domain on a network, the communication device including a communication unit that executes communication with another node and a control unit that controls communication executed by the communication unit. The control unit operates such that, when having received, from a user, a request regarding an application that chains one or more application functions (AFs) to act on a packet flowing in the network, the control unit acquires information regarding the application from a second zone being a management domain other than the first zone, and then calculates a deployment destination of the AFs in the network including the first zone and the second zone based on the information.

  • Publication number: 20240340344
    Abstract: An information processing apparatus operates as an IoTSP 1 (corresponding to an example of “first IoTSP”) that provides a service for causing a user to acquire sensor data. The information processing apparatus includes a communication unit that executes communication with another IoTSP (corresponding to an example of “second IoTSP other than the first IoTSP”) and a control unit that searches the sensor data corresponding to an acquisition request of the user via an application and responds to the user with the searched sensor data. The control unit searches the sensor data from the other IoTSP via the communication unit based on an identifier of the other IoTSP included in the acquisition request and policy information indicating propriety of information sharing between the IoTSPs and uses a protocol interface including the same procedure as a procedure between the application and IoTSP1 when searching the sensor data.

  • Patent number: 10622263
    Abstract: There is provided a semiconductor device and a method for manufacturing a semiconductor device. Within the N-type semiconductor layer formed from a high resistance N-type substrate, the P-type well diffusion layer and P-type extraction layer are formed and are fixed to ground potential. Due thereto, a depletion layer spreading on the P-type well diffusion layer side does not reach the interlayer boundary between the P-type well diffusion layer and the buried oxide film. Hence, the potential around the surface of the P-type well diffusion layer is kept at a ground potential. Accordingly, when the voltages are applied to the backside of the N-type semiconductor layer and a cathode electrode, a channel region at the MOS-type semiconductor formed as a P-type semiconductor layer is not activated. Due thereto, leakage current that may occur independently of a control due to the gate electrode of a transistor can be suppressed.
