The invention discloses a bandwidth determination method and device and a storage medium, and belongs to the technical field of networks. The method comprises the following steps: receiving a first data packet and a second data packet; when it is determined that the first data packet and the second data packet are continuously sent by the sending end, calculating the receiving time difference between the second data packet and the first data packet, using the receiving time difference for representing the time length consumed by the receiving end in the process of receiving the second data packet; calculating a quotient between the data length of the second data packet and the receiving time difference as a predicted bandwidth; and determining the bandwidth between the sending end and thereceiving end according to the calculated predicted bandwidth. According to the method and the device, the time length consumed in the process of receiving the second data packet can be accurately determined at the receiving end according to the receiving time difference of the two successively sent data packets; therefore, the accurate bandwidth is calculated, the calculation accuracy is improved, the matched code rate is set according to the calculated bandwidth, and the bandwidth utilization rate can be improved as much as possible under the condition that normal data transmission is guaranteed.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 201711484244.1 and the title of the invention "Bandwidth Determination Method, Device and Storage Medium" filed with the State Intellectual Property Office of China on December 29, 2017, the entire contents of which are incorporated herein by reference In this application. technical field [0002] The present invention relates to the field of network technology, in particular to a bandwidth determination method, device and storage medium. Background technique [0003] The process of transmitting data between the sending end and the receiving end will be affected by the code rate and bandwidth. The code rate refers to the number of data bits transmitted by the sending end per unit time. For the number of data bits to be transmitted, when the code rate is set too small and the code rate is smaller than the bandwidth, the bandwidth utilization rate will be small, resulting ...
