Abstract
Official abstract text for this publication.
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.
