Abstract: A time synchronization client having a timer, transmits request frames to request a reference time to a server having a reference timer, and receives a reply frame of respective request frames from the server. Based on an accuracy of the timer to the reference timer and an allowable time difference therebetween, an allowable measurement period is calculated. For the respective request frames transmitted within the allowable measurement period before a current time of the timer, an estimated time difference therebetween is calculated, based on a first time of the timer when the request frame is transmitted, a second time of the reference timer when the server receives the request frame, a third time of the reference timer when the server transmits the reply frame, and a fourth time of the timer when the reply frame is received. The time of the timer is corrected based on the estimated time difference.

Abstract: 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.
