Problems solved by technology

[0002] During data transmission, if unreliable protocols such as UDP are used, data may be delayed or lost when network jitter or failure occurs. If the receiving end does not request the sending end to retransmit the unreceived data in time, the reception may be affected. The use of end-to-end data, for example, if the above-mentioned transmitted data is live streaming data, it may cause blurred screen, freeze or delay when playing live streaming data, but if the receiving end requests the sending end to retransmit too early Unreceived data may cause data duplication and redundancy. For example, data is delayed due to network jitter during transmission. If the unreceived data is requested to be retransmitted too early, after receiving the retransmitted data, there may be Delayed data will be received, resulting in redundancy and the problem of occupying network bandwidth

Abstract

The invention discloses a data retransmission method, a data retransmission device, terminal equipment and a storage medium. The data retransmission method is applied to a receiving end, and comprisesthe steps of: receiving data packets transmitted by a transmitting end, wherein each data packet carries a serial number used for describing the uniqueness of the data packet, the serial numbers areconsecutive, and the receiving end and the transmitting end are based on an unreliable protocol; storing a missed serial number in a pre-retransmission cache region when detecting that the serial numbers of the acquired data packets are not consecutive, recording storage time of the missed serial number and calculating to-be-used time of the data packet corresponding to the missed serial number; and requesting for retransmission of the data packet of a target serial number to the transmission end or a third end storing the data packet corresponding to the missed serial number, wherein the target serial number comprises a serial number with the storage time reaching first preset time or the to-be-used time not longer than second preset time. The data retransmission method, the data retransmission device, the terminal equipment and the storage medium aim to solve the problem of data retransmission redundancy or influence on data usage in the existing data retransmission technology.
