摘要： A communication device transmits a first packet to a first device via a network device, and receives a second packet from the first device. A transmission time between the communication device and the first device is calculated using time indicated by the communication device when the communication device transmitted the first packet, time indicated by the first device when the first device received the first packet, time indicated by the first device when the first device transmitted the second packet, time indicated by the communication device when the communication device received the second packet. A size of the first packet is set so that wait time of the first packet at the network device is within predetermined period. The wait time is calculated by assuming that a third packet transmitted from a second device is inputted to the network device before the first packet is inputted to the network device.

摘要： A receiving unit receives from a second terminal, a switching request message requesting switching of a counterpart of a communication that a third terminal is establishing with a first terminal, from the first terminal to the second terminal. When receiving the switching request message, a selecting unit selects one of the second and third terminals based on a predetermined rule, as a transmission source terminal that transmits an establishment request message requesting establishment of a communication between the second terminal and the third terminal. A transmitting unit transmits to the transmission source terminal, a transmission request message requesting transmission of the establishment request message.
