  • Publication number: 20150207877
    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.

  • Patent number: 8976818
    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.

  • Publication number: 20150049627
    Abstract: According to one embodiment, a measuring apparatus includes a first calculation unit and a second calculation unit. The first calculation unit calculates, as a communication delay for each request packet, a half of a round trip time based on first time information included in the request packet and second time information included in a response packet, the request packet requesting a notification of a reference time, the response packet being a response to the request packet. The second calculation unit calculates one of one or more communication delays not more than a threshold among a plurality of communication delays as an estimated delay of each response packet to be transmitted from the one or more second devices.

  • Publication number: 20140355629
    Abstract: There is provided a communication apparatus communicating with a master apparatus generating events at a constant time interval via a network, including: a clocking unit clocking a time; an event generator generating an event based on the clocking unit in accordance with event interval information specifying a time interval for event generation; a storage storing a first timestamp representing a time when the event is generated in the event generator; a receiver receiving, from the master apparatus, a frame containing a second timestamp representing a time of the event generated in the master apparatus; and an event interval corrector correcting the event interval information so as to make a timing of event generation in the event generator closer to a timing of event generation in the master apparatus based on the first timestamp, the second timestamp, and a pre-acquired time difference between the clocking unit and the master apparatus.
