The present invention relates to the technical field of cloud storage. Provided are a data transmission method and apparatus for a family cloud service system. The method comprises: when data transmission with a device end is needed, sending a penetration instruction to a server, such that the server sends, according to the penetration instruction, a second transmission protocol message address of a control end to the device end, and sends a first transmission protocol message address of the device end to the control end; sending a second transmission protocol message to the device end according to the first transmission protocol message address of the device end, and meanwhile receiving a first transmission protocol message sent by the device end according to the second transmission protocol message address of the control end, thereby achieving penetration between the control end and the device end; when the penetration succeeds, transmitting data with the device end by using a transmission protocol; and when the penetration fails, transmitting data with the device end in a server forwarding manner. The present invention improves the efficiency and stability of data transmission between the control end and the device end. |
