Problems solved by technology

[0004] However, when the network transmission environment fluctuates greatly or the noise is large, the round-trip time of receiving the acknowledgment packet each time the host successfully sends a data packet may vary greatly, resulting in large fluctuations in the results of linear filtering, and it is impossible to obtain a relatively accurate The reference value of the round-trip time greatly affects the accuracy of the timeout retransmission time, so that the host side performs invalid retransmission and delayed retransmission of a certain data packet.

Abstract

The embodiment of the invention discloses a data retransmission method and device, equipment and a storage medium. The method comprises the following steps: for current target data which are confirmed to be successfully transmitted each time in a current network, filtering actual round-trip time of the target data in the current network by adopting an extended Kalman filtering algorithm to obtain estimated round-trip time of the current network after the current target data are transmitted; and estimating the current timeout retransmission time in the current network based on the estimated round-trip time of the current network after the current target data is transmitted. According to the technical scheme provided by the embodiment of the invention, the extended Kalman filtering algorithm is utilized to iteratively update the estimated round-trip time during data transmission in the current network, and the real-time performance and accuracy of the estimated round-trip time during data transmission in the current network are ensured, so that the accuracy of timeout retransmission time in the current network is improved; and the phenomena of invalid retransmission and delayed retransmission of the data packet are avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data transmission, and in particular, to a data retransmission method, device, device, and storage medium. Background technique [0002] With the rapid development of Internet technology, in the live broadcast application, the anchor will continuously transmit corresponding data packets to the server to ensure the normal start of the live broadcast. At this time, due to problems such as network congestion, there may be network packet loss during the transmission process. Therefore, in order to ensure the integrity of data transmission, it is necessary to retransmit the data that may be lost. When detecting whether the data packet sent by the anchor is lost, a retransmission timeout (Retransmission Timeout, RTO) will be set, so that after a certain data packet is sent, the data packet has not been received beyond the retransmission timeout When the acknowledgment packet is recei...
