In addition, in the following description, specific details are provided in order to provide a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.

As shown in fig. 1, the present embodiment provides a data downloading method, which includes a cloud server for storing data and a plurality of application ends communicatively connected to the cloud server, where the application ends directly or indirectly download or upload data from the cloud server.

The application terminals are distributed in different local area networks, and the different application terminals can be in communication connection and transmit data. That is, the application terminals in the lan can mutually transmit data, and the application terminals in the lan can mutually transmit data.

In the prior art, if the plurality of application ends need to download data, the application ends are all selected to be directly connected with the cloud server, so that the data is acquired, and in consideration of the fact that the bandwidth of the cloud server is limited, all the application ends simultaneously download from the cloud server, the downloading speed is low, and the burden of the cloud server is increased.

Based on this, in this embodiment, each application is not required to directly download data from the cloud server, but each lan selects a master box to communicate with the outside world on behalf of the corresponding lan.

Referring to fig. 1 and 2, there are A, B, C … … a plurality of local area networks, the local area network a has a plurality of application ends A1, A2, A3 … …, the local area network B has a plurality of application ends B1, B2, B3 … …, the local area network C has a plurality of application ends C1, C2, C3 … …, and each local area network generates the application ends A1, B1, C1 … … as a main box of the corresponding local area network through election. All the main boxes need to broadcast local area network information of local area networks where the main boxes are located to other local area networks and cloud servers and establish links, wherein the local area network information comprises network numbers and network addresses corresponding to the local area networks.

The network number is a number corresponding to the local area network, and can be distributed by a cloud server or can be converted by related information to generate a unique number.

The network address is used for receiving and transmitting data so that the cloud server can send the data to the local area network or download the data from the main box of other local area networks.

Of course, the main boxes also download data in a P2P mode instead of directly from the cloud server, and other application ends except the main boxes in the local area network can download data from the main boxes in a conventional mode.

In one embodiment, as shown in fig. 3, the steps of generating a master box by a plurality of application ends in the lan include:

s101: each application in the lan periodically broadcasts packets carrying its own information in the lan, and these packets may carry their own information, such as ID numbers, storage status, etc.

S102: when one application end receives data packets sent by other application ends, judging all the data packets through a first preset condition, and enabling the application end meeting the first preset condition to be a main box.

The method is equivalent to internally determining who becomes the main box, and can select which ID number in the local area network is the largest or smallest as the main box or the application end with the optimal transmission performance as the main box as long as a certain application end in the local area network meets a first preset condition.

Of course, besides determining the main box internally, the cloud server can also perform specified allocation.

It should be noted that, the application end corresponding to the main box is not always unchanged, because once a new application end member is added in the lan, the application end corresponding to the main box may be changed under the first preset condition. But whichever application end is elected as the master box, the lan information that it sends to the cloud server and other lans includes the network number and network address that do not change, i.e., the lan is used anyway.

After the main boxes of different local area networks are selected, the main boxes can download data from the cloud server in a P2P downloading manner, and the specific downloading process can adopt the existing conventional P2P downloading algorithm, so that the embodiment provides a step of how the main boxes download data from the cloud server according to practical situations, as shown in fig. 4:

s201: firstly, a cloud server monitors the Round-Trip Time (RTT) of a ping packet between a main box of each local area network and the cloud server, and the RTT reflects the Round-Trip Time between the main box and the cloud server.

S202: when the RTT time between the main box and the cloud server meets a second preset condition, the cloud server sends data to the network address of the corresponding main box, and the main boxes become seed boxes after receiving the data.

For a main box with RTT time not meeting a second preset condition with the cloud server, the main box establishes a link with an application end serving as a seed box and downloads data, and the data is not downloaded from the cloud server.

The second preset condition may be a master box having an RTT less than a preset time value, or several master boxes having a minimum RTT.

Specifically, the process of sending data from the cloud server to the network address of the corresponding master box is as shown in fig. 5:

s301: the cloud server sends indication information to all main boxes, wherein the indication information comprises a list of seed boxes and network addresses of the seed boxes.

After the cloud server screens out the application terminals serving as the seed boxes from all the main boxes, the cloud server is required to broadcast indication information of the seed boxes to all the main boxes, wherein the indication information comprises a list of application terminals serving as the seed boxes and network addresses of the application terminals.

S302: after receiving the indication information, the main box judges whether the main box is in a seed box list or not, if yes, the main box establishes a link with the cloud server and downloads data, and if not, other main boxes which become seed boxes are selected to establish links and download data.

For the application end which becomes the seed box, the application end is naturally responsible for downloading data from the cloud server and sending data to the main box of other non-seed boxes, and when the main box checks that the main box is not the seed box, the main box can establish a link with the main box according to the network address which becomes the seed box and download the data.

In the process of downloading data from the main box, the data downloading mode with other application ends in the local area network can be direct downloading from the main box, such as http downloading, or the downloading mode of layer-by-layer fission of the rest application ends.

When downloading, other application ends in the local area network can download data from the main box after the main box is downloaded, or can download data from the main box simultaneously in the downloading process of the main box. For the former, when the downloading of the main box is completed, the main box can send downloading instructions to other application ends in the same local area network, and after receiving the downloading instructions, the other application ends in the same local area network establish links with the main box and download data.

The embodiment also provides a remote broadcasting control system, which comprises a central server and a plurality of broadcasting boxes connected with the central server, wherein the central server stores data to be broadcasted, and the broadcasting boxes and the cloud host download the data by adopting the downloading method in the embodiment.
