Abstract

The present application discloses a file transmission method, including: dividing a preset number of file fragments from the transmitted file data in units of a preset fragment size; transmitting file fragments, and recording the transmission rate of each file fragment respectively ; Determine the network transmission rate at the next moment according to the transmission rate of the file segment; update the fragment size value according to the network transmission rate at the next moment, and use the updated fragment size value as a unit, among the untransmitted data in the transmitted file Divide a preset number of file fragments; repeatedly determine the network transmission rate at the next moment according to the current file fragment transmission rate to update the fragment size value, divide the preset number of file fragments from the untransmitted data and Transfer is transferred file data. This application achieves the purpose of making full use of the current network transmission data traffic capacity and rationally utilizing the network data transmission traffic capacity by means of real-time adaptation between the fragment size value and the network transmission rate at the next moment.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a file transmission method and device. Background technique [0002] In the process of data transmission, in order to reduce the repeated transmission of the entire file caused by the failure of data transmission due to network abnormalities, it is necessary to divide the file into equal-sized fragments according to the fixed fragmentation size, that is, to divide the file into multiple file fragments, and then serially transmit these multiple file fragments separately, and reorganize into a complete file after receiving all the file fragments of the file at the receiving end; through the above method, if encountering network abnormalities, generally It will only affect individual file fragments in the file. At this time, it is only necessary to repeatedly transmit the failed file fragments, thereby avoiding the repeated transmission of the entire file, thereby improving the util...
