And 102, the server generates an upgrading verification request based on the program upgrading request and the first program upgrading file, and sends the upgrading verification request to the target equipment.
And 103, the server correspondingly performs program upgrading processing according to verification result information returned by the target equipment for the upgrading verification request so as to upgrade the program of the target equipment.
In one embodiment, there may be multiple ways to obtain the first program upgrade file and determine the target device based on the program upgrade request. For example, the server extracts the file information from the program upgrade request, obtains a first program upgrade file corresponding to the file information, and obtains first version information corresponding to the first program upgrade file, where the first version information may be a version number or the like.
The server extracts the first address information from the program upgrading request and determines the target equipment corresponding to the first address information.

For example, after sending the second encrypted data block and the corresponding number and second check code to the target device, the server receives the first response information returned by the target device. If the transmission is determined to be successful according to the first response information, the server continues to transmit the third encrypted data block and the corresponding number and second check code.
And if the transmission failure is determined according to the first response information, the server acquires the number information from the first response information, determines that the second encrypted data block fails to be transmitted based on the number information, and retransmits the second encrypted data block corresponding to the number information, the number and the second check code.
And the server records the retransmission times of retransmitting the encrypted data block corresponding to the number information and the number and the second check code, and stops data transmission and transmits upgrading program transmission failure information to the client if the retransmission times are greater than or equal to a preset time threshold. The number threshold may be 3 times, etc., for example, if the number of retransmissions is equal to 3 times, the server stops data transmission and transmits upgrade program transmission failure information to the client.
