  • Retransmission control device, method, and computer readable medium for time sensitive network communications
    Patent number: 11677515
    Abstract: A communication device (101) transmits data by switching types of data to be transmitted by a unit of a time slot. A data transmission unit (6) transmits transmission data during a time slot corresponding to a type of the transmission data. Further, the data transmission unit (6) decides a retransmission time for performing a retransmission of the transmission data based on a time when a transmission of the transmission data has been completed.
    Type: Grant

  • Communication device, communication method and computer readable medium
    Patent number: 11463369
    Abstract: A communication device (10) communicates in a network in which a TSN (Time-Sensitive Networking) technique is used. A time slot management unit (21) notifies that time slots in the TSN technique have been switched. A data receiving unit (23) stores reception data in a reception data storage unit (25) when the reception data received from other communication devices (10) is not transmission data transmitted during a current time slot. When the time slot management unit (21) notifies that the time slots have been switched, the data receiving unit (23) delivers to a reception task (27), the reception data which is the transmission data transmitted during a time slot after being switched and is stored in a reception data storage unit (25).
