Problems solved by technology
The network packet loss rate refers to the ratio of the lost part of the data packet to the total number of transmitted data packets. When the network packet loss rate is relatively high, the retransmission of the lost data packet will cause a relatively large network delay.

The invention discloses a network data transmission method and device, and electronic equipment, which can solve the problem of long network delay due to retransmission of lost data packets in the prior art. At a sending end, the method comprises the steps of caching acquired data packets to obtain backup data packets; sending the acquired data packets to a receiving end; and when the number of the backup data packets is equal to a predetermined number, extracting all the backup data packets, calculating out redundant data packets based on the backup data packets and an FEC algorithm and sending the redundant data packets to the receiving end, wherein the backup data packets and the calculated redundant data packets serve as a group, so that whether the number of the data packets belongingto the same group is equal to the predetermined number or not is judged by the receiving end. At the receiving end, the method comprises the steps of receiving the data packets sent by the sending end and carrying out caching; judging whether the number of the data packets belonging to the same group in the backup data packets is equal to the predetermined number or not is judged; and if so, calculating out the lost data packets based on the backup data packets and the FEC algorithm. The network data transmission method and device is suitable for recovery of the lost data packets in UDP datatransmission.
Description
technical field [0001] The invention relates to the field of computer application technology, in particular to a network data transmission method, device and electronic equipment. Background technique [0002] Currently, in the mobile Internet, when network data is transmitted, data retransmission is sometimes performed due to network packet loss. Packet loss, as the name suggests, refers to the loss of communication data packets in communication, which means that the data of one or more data packets cannot reach the destination through the network. Packet loss may cause jitter in streaming media technology, VolP, online games and video conferencing, and affect other online applications to a certain extent. When packet loss occurs, the receiver of the network data transmission can ask the sender to retransmit the lost data packet, or the sender can automatically resend the lost data packet. The network packet loss rate refers to the ratio of the lost part of the data packe...
