Embodiment 1
[0018] figure 1 It is a schematic diagram of a network architecture applicable to the download method provided in Embodiment 1 of the present invention. The network architecture includes a download server 1, a download device 2, and storage devices 31 and 32. Here, one download device 2 is taken as an example, but there may also be multiple. Two storage devices are taken as an example, which are the storage device 31 and the storage device 32 respectively.
[0019] Each downloading device 2 can access the network through at least two network access methods, which are wired and WIFI as examples here. In these two access modes, the access addresses assigned to the downloading device 2 are IP address B1 and IP address B2 respectively. The storage device 31 has an IP address C, and the storage device 32 has an IP address D. Since downloading device 2 has two network access modes, data can be downloaded from storage devices 31 and 32 respectively through two IP addresses, so thi...
Embodiment 2
[0049] image 3 A schematic flow chart of the download method is provided for Embodiment 2 of the present invention. This embodiment includes the following steps:
[0050] Step 301, the downloading device accesses the network through at least two network access methods, so as to obtain the access addresses assigned by each network access method.
[0051] Network access methods include wired connection and wireless connection. Wherein, the wireless connection specifically may include: Bluetooth, 3G, 2G, GPRS, and WIFI. In this embodiment, the downloading device has three network access modes as an example, which are wired, bluetooth and WIFI, respectively corresponding to access addresses IP1, IP2 and IP3.
[0052] Step 302, the download device sends a download request to the download server, and receives a download list returned by the download server. The download list includes data information and data storage addresses of at least two data blocks of the target to be down...
Embodiment 3
[0066] Figure 4 It is a schematic flowchart of the downloading method provided by Embodiment 3 of the present invention. The above-mentioned embodiment has described in detail the downloading method when the downloading device has three network access modes. illustrate.
[0067] Step 410: Send a download request to the download server, and receive a download list returned by the download server, wherein the download list includes data information and data storage of at least two data blocks of the target to be downloaded indicated by the download request address;
[0068] Step 420, according to the data storage address of each data block and the access address corresponding to the WIFI access mode, query whether the same WIFI hotspot is accessed as the storage device; if yes, execute step 430, if not, execute The establishment operation of at least two download channels in step 440;
[0069] Step 430, according to the access address and data storage address corresponding ...
