摘要： A communication device searches for a desired communication device and requests a service, without being conscious of the status of the power supply of other communication devices on a network, and achieves a reduction in power consumption. The communication device includes a main processing unit to process main service provided for other communication devices, a network processing unit to transmit and receive a request packet and a response packet among other communication devices, and an integrated power supply unit to stop supplying power to the main processing unit in a state of being able to supply it again and to supply the power to the network processing unit. The network processing unit is provided with an automatic responding unit to determine whether or not it can respond to the received request packet only by itself and, when the response is possible, to transmit the response packet to the communication device, and a power supply controlling unit, when the response is not possible, to control a main-power supply unit to supply the power to the main processing unit.

摘要： A communication apparatus which is capable of performing bi-directional communication via a router in a local network including one or more routers is provided. An upper segment determination section obtains address range information under an upper router which is connected on an external network side of a router to which the communication apparatus is connected. A terminal communication path holding section connects and holds a communication path to another communication apparatus in the local network. A message relay section relays a communication message from the other communication apparatus. When the terminal communication path holding section receives a first request message requesting to establish a communication path from the other communication apparatus, the terminal communication path holding section stores source address information of the received first request message, and transmit a response message to the stored source address information to establish a communication path to the other communication apparatus.

摘要： To provide, without requiring a user to have special knowledge or to pay a high cost, a communication apparatus which enables detection of an apparatus present on a different network in a router multistage network comprising a plurality of routers. When a communication apparatus (101) cannot detect, on a network thereof, a desired apparatus, the communication apparatus requests a connection support server (001) securing communication paths with all the apparatuses on a home network, to relay an apparatus detection request. The connection support server (001) transfers the request to relay the apparatus detection request, to an arbitrary apparatus belonging to a different network from the network to which the communication apparatus (101) belongs, and the arbitrary apparatus, by proxy, performs an apparatus detection, and transfers information about a detected apparatus to the connection support server (001). By obtaining the information from the connection support server (001), the communication apparatus (101) detects the apparatus on the different network.

摘要： Provided is a communication terminal capable of establishing a P2P communication path with a communication terminal connected to a different private network. A communication terminal (10) transmits and receives messages to and from a server (30) via a router (11), thereby examining a relay characteristic of the router (11). When the examined relay characteristic of the router (11) is Port Reuse, the communication terminal (10) determines address information, which contains at least a port number of the communication terminal (10), which port number is to be used for P2P communication with a communication terminal (20), to be address information about the router. The communication terminal (10) exchanges the determined address information about the router (11) with the communication terminal (20). Based on the exchanged address information, the communication terminal (10) establishes a P2P communication path with a communication terminal (20).

摘要： It is an object of the present invention to provide a QoS controllable communication device and communication system. A device 114 such as a first IP telephone comprising a QoS control unit 121 of the present invention transmits first transmission control data to a device 111 such as a PC performing lower priority communication. The first transmission control data includes data for changing the communication path of the lower priority communication, and the PC 111, having received the first transmission control data, performs subsequent lower priority communication through the first IP telephone or other device 114, enabling the first QoS control unit 121 to perform priority control. Because the present invention employs widely used protocols such as ARP and ICMP, the device 111 receiving the control data does not need protocols specific to the present invention.
