PROCÉDÉ ET APPAREIL D'ENVOI DE DONNÉES, ET PROCÉDÉ ET APPAREIL DE RÉCEPTION DE DONNÉES

摘要

The present disclosure discloses a data transmitting method, a data receiving method, and a device. The method includes: generating, by a first device, data messages based on a to-be-sent data stream; transmitting, by the first device, the data messages to a second device based on a packet transmission rate; recording, by the first device, the number of transmitted data messages; when the number of the transmitted data messages reaches a preset number for one batch, transmitting, by the first device, a verification message to the second device; receiving, by the first device, a verification acknowledgement returned by the second device, and determining, by the second device, a packet loss rate of the batch of data messages; updating, by the first device, the packet transmission rate based on packet loss rates of multiple batches of data messages. Because the packet loss rate reflects the current network condition to a great extent, based on the packet loss rate, the packet transmission rate may be updated to adjust the packet transmission rate of the first device to better accommodate the fluctuation of the network bandwidth, thus reducing the occurrence of the packet loss phenomenon. Further, the first device may perform verification with the second device batch by batch, which reduces the occupation of network resources in the verification process.
