Wherein, the receiving end includes but is not limited to a desktop and a server.
For example, a dedicated line for transmitting messages and files is established between the enterprise a and the bank B, and in order to avoid that the transmission of a message is affected when the time for transmitting a large file occupies the dedicated line, the preset value may be set according to the bandwidth of the dedicated line, for example, the bandwidth of the dedicated line is 2MB/s, and the preset value is 128KB, so that the transmission of the file to be transmitted can be completed quickly without affecting the transmission of subsequent messages. And the size of the file to be sent put into the file sending queue by the sending end of the enterprise A is smaller than or equal to the preset value. Before sending a file to a receiving end of a bank B, a sending end of an enterprise A judges whether a message exists in a message sending queue, if the sending end judges that no message exists in the message sending queue, the sending end of the enterprise A acquires the file to be sent from the file sending queue, and then sends the file to be sent to the receiving end of the bank B.
