Abstract

The application discloses a document transmission method. The document transmission method comprises the following steps: segmenting data of a transmitted document into document fragments with a preset number by adopting a preset fragment size value as a unit; transmitting the document fragments, and respectively recording the transmission rate of each document fragment; determining the network transmission rate of a next moment according to the transmission rate of each document fragment; updating the fragment size value according to the network transmission rate of the next moment, and segmenting data which are not transmitted in the transmitted document into document fragments with the preset number by adopting the updated fragment size values as a unit; and re-determining the transmission rate of a network at the next moment according to the transmission rate of the current document fragment so as to update the fragment size value, segmenting data which are not transmitted into the document fragments with the preset number, and transmitting the data of the transmitted document. By matching the fragment size value with the transmission rate of the network at the next moment, a purpose for adequately utilizing the current network transmission data flow capacity and reasonably utilizing the data transmission flow capacity of the network can be realized.

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...
