Network bandwidth detection method, device, system and equipment and storage medium

The invention relates to a network bandwidth detection method, device and system, equipment and a storage medium. The method comprises the following steps: receiving a plurality of packet pairs sent by a client, wherein each packet pair at least comprises two data packets; screening the packet pair meeting the condition as a target packet pair, determining an estimated rate of the target packet pair, and sending the estimated rate to the client; receiving a packet group sent by the client at the estimated rate, wherein the packet group comprises a plurality of data packets; determining a target rate corresponding to the packet group, and determining a network bandwidth according to the target rate of the packet group; and sending the determined network bandwidth to the client. The network bandwidth detection of the network line is completed by combining the advantages of the packet pair method and the packet group method, and the network bandwidth detection can be realized more quickly and more accurately. 本申
