The first server may determine, after the download permission verification passes, that a certain server that can satisfy the download requirement of the terminal device, such as download speed, download delay, and the like, is a second server. And the first server sends a downloading instruction to the second server. The download instruction may include information of the terminal device and information of the target data. The download instruction instructs the second server to send the target data to the terminal device. As shown in fig. 2, the target data includes first data and second data; the first server stores the second data, and the second server stores the first data and does not store the second data. For example, the first server may send a download instruction to the second server to instruct the second server to send the target data to the terminal device when the load is heavy or the requirement of the terminal device for downloading the target data cannot be met. The terminal device downloads the target data through the second server to meet the requirement of the terminal device on the downloading speed.
The second data is stored in the first server. The second server stores first data and does not store the second data. The second data may be, for example, encrypted data in the target data, which is changed every time of downloading. The first data may be data in the target data that is not changed, i.e., the portion of data in the target data is not changed each time it is downloaded. The first server transmits the second data to the second server, and the second server combines the received second data and the first data stored therein into the target data and transmits the target data to the terminal device. The embodiment of the present invention does not limit the types and specific contents of the first data and the second data.
The access between the servers is generally fast. When the first server cannot meet the download requirement of the terminal device, the second server may be designated to send target data to the terminal device, and data lacking in the second server may be sent to the second server.
