In this embodiment of the application, each of the transfer second neighboring devices sends the allocated transmission file segment, so that the electronic device can obtain a plurality of transmission file segments.
It should be noted that the plurality of relay second neighboring devices may directly transmit the transmission file segments of the first neighboring device to the electronic device, or may be divided into a plurality of portions, where each portion is used to transmit the transmission file segments of the first neighboring device, so that the plurality of transmission file segments are transmitted to the electronic device through a plurality of relays, thereby improving transmission efficiency.

In addition, the missing segments to be downloaded can be searched according to the serial numbers, and the fault processing capacity is improved. In one embodiment, the method further comprises: when the target transmission duration is reached, acquiring a plurality of target numbers corresponding to the plurality of transmission file fragments; if the difference between the plurality of numbers and the plurality of target numbers is one reference number, determining a transit second adjacent device corresponding to the reference number as a reference adjacent device; and if the reference adjacent equipment fails, receiving a transmission file segment corresponding to the reference adjacent equipment and sent by the candidate relay second equipment.

The alternative relay second device may be, without limitation, one of the plurality of relay second neighboring devices except the reference neighboring device, which is closest to the reference neighboring device, and has the fastest network speed or the highest evaluation value.
It can be understood that, when the target downloading duration allocated for downloading the file segments to be downloaded reaches, the reference neighboring device is determined according to the target numbers corresponding to the acquired multiple file segments to be downloaded and the numbers allocated in advance, and when the reference neighboring device fails, the candidate device is adopted to acquire the file segments to be downloaded corresponding to the reference neighboring device, so that the failure handling capability can be improved, and the downloading rate can be improved.
