    摘要： A power line communication apparatus transmits a signal to a first power line communication apparatus through a power line connecting to a second power line communication apparatus. The power line communication apparatus includes an information retriever for retrieving transmission rate information indicating both a first transmission rate and second transmission rate. The first transmission rate correspond to a first path of the power line along which the signal is directly transmitted to the first power line communication apparatus, and the second transmission rate corresponds to a second path of the power line along which the signal is transmitted through the second power line communication apparatus to the first power line communication apparatus. A selector selects, based on the transmission rate information, a path corresponding to a higher transmission rate among the first and second paths. A transmitter transmits the signal through the selected path.

    摘要： The present invention provides a repeater which automatically closes a dynamically opened port in accordance with prior setting, the repeater including: a port mapping table where a global IP address and an external port number, or an external port number on the Internet is associated with a local IP address and an internal port number of a terminal connected to a LAN; a control unit which, receiving a communications packet to which an external port number is specified, converts the external port number to an internal port number based on the port mapping table and transfers the internal port number to the LAN; a timer unit which counts the unoccupied time of the port after transferring a communications packet to which an external port number is specified; and a port management unit which checks whether the registered machine is present on the LAN and in case it is absent, deletes registration concerning the external port number from the port mapping table.

    摘要： An IP device (for example, network cameras 3a, 3b, and 3c) connectable to a router (for example, a router 2) makes a request to the router for assignment of a port number when a predetermined operation is performed, and notifies a management server 6 connected to a wide area network of address data containing an assigned port number when the port number is assigned from the router, wherein address data containing the port number can be registered in the management server 6 on the wide area network, so that, even when access is made from the terminal 4 on the wide area network side with a port number that is locally updated, access is made possible by transmitting address data of the IP device to the terminal 4.

    摘要： A power line communication apparatus controls a transmission using a plurality of parameters. The power line communication apparatus includes: a registration processor which performs a registration process for achieving a state to be communicable with another power line communication apparatus through a power line by use of transmission data based on a first parameter set at a first value and a second parameter set at a second value, a parameter controller which changes the first parameter to the third value to lengthen a communicable distance and the second parameter to the fourth value to shorten the communicable distance when the registration process has ended in failure. When the registration process has ended in failure, the registration processor retry the registration process by use of transmission data based on the first parameter set at a third value and the second parameter set at a fourth value.
