Example 2

FIG. 2 is a schematic structural diagram of a system for downloading data according to an embodiment of the present invention, where a node requester A, The seed 1 and the nodes in the network (node 1, node 2, and node N) are respectively connected to the server. The method for downloading data provided by the embodiment of the present invention is specifically described below with reference to FIG. Referring to FIG. 3, an embodiment of the present invention provides a method for downloading data, where the method includes:

201: The node requester A needs to download the data B, and then queries the server for the information of the seed (ie, the node containing the data B).

Specifically, the querying the information of the seed to the server may be performed by sending a query message to the server, where the query message carries the information of the data that the node requester A needs to download, for example, the node requester A needs to download the data B in this embodiment. , the query message carries the information of the data B. In addition, the query can be performed by any feasible query method in the prior art, which is not specifically limited, and can be flexibly selected according to actual application conditions.

202: The server queries the seed information, and returns the seed information to the node requester A.

The seed information includes the identifier of the seed, the type of the network of the seed, and the IP (Internet Protocol, International Protocol) address of the seed. And if the node requester A sends a query message to the server for querying in step 201, the step may specifically be: the server receives the query message, and queries the node containing the data B according to the query message, and then returns the query to the node requester A. The result message; wherein, the query result message carries the information of the seed queried by the server. There may be a large number of queried seeds, or there may be only a few, for example: This embodiment sets a query to a seed as seed 1, but is not limited thereto.

It should be noted that, for convenience of description, the seed queried by the server may be referred to as a current seed. Correspondingly, the information that returns the seed to the node requester A is the information that returns the current seed to the node requester A. Accordingly, the above seed 1 is the current seed.

203: The node requester A receives the information of the current seed, downloads the data B from the current seed, and determines whether the total number of the current seed is less than a preset seed number threshold. If not, performs 204; otherwise, performs 207.

The total number of current seeds is the sum of the number of current seeds obtained by the node requester A; the preset seed quantity threshold may be set according to the actual situation and the experience value of the node requester A. For example, in this embodiment, the preset seed number threshold is 2.

It should be noted that, after receiving the information of the current seed, the node requester A can obtain information such as the identifier of the current seed, the network type of the current seed, and the IP address of the current seed, and according to the information, establish a contact with the current seed, thereby Download data B in the current seed.

204: Node requester A indicates that the current seed extends the new seed.

Specifically, when the node requester A indicates that the current seed expands the new seed, it may be performed by sending a message, a signal or an instruction to the current seed. For example: The extended seed quantity message can be sent to the current seed, and the corresponding identifier is carried in the extended seed quantity message to convey that the current seed quantity is insufficient, and the node requester A cannot download the data. Ask, indicating that the current seed is expanding the new seed. For example: By carrying "1" in the extended seed quantity message, it indicates that the current seed quantity is insufficient, indicating that the current seed expands the new seed; carrying the "0" in the extended seed quantity message indicates that the current seed quantity is sufficient, and the current seed does not need Expand new seeds. This is not specifically limited, and can be flexibly set according to actual application conditions.

Further, the step 204 may further specifically: the node requester A indicates that the current seed extends the new seed, and indicates the current seed to expand the number of new seeds, that is, the node requester A in this step indicates that the current seed expands the new seed. The node requester A may also indicate that each current seed specifically expands several new seeds according to the total number of current seeds, the specific condition of each current seed itself, and/or the size of a preset seed number threshold. If it is assumed that there are 3 current seeds, which are the first current seed, the second current seed, and the third current seed respectively, and the preset seed number threshold is 10, the node requester A can according to the total number of current seeds, each current The specific condition of the seed itself and the preset seed number threshold indicate that the first current seed expands 3 new seeds, the second current seed expands 2 new seeds, and the third current seed expands 2 new seeds. It should be noted that the node requester A indicates that each current seed specifically expands several new seeds without specific limitation, and can be flexibly set according to actual application conditions.

205: The current seed receives an indication to extend the new seed, expanding the new seed.

Specifically, the current seed receives an indication of expanding the new seed; the current seed acquires the idle node, and indicates that the idle node downloads the data B from the current seed; the idle node receives the indication of downloading the data B from the current seed, and the downloaded data B becomes new seed. The idle node refers to a node whose current downlink data and uplink data of the node are smaller than a preset traffic threshold. Obtaining a free node may be that the current seed itself queries each node in the network to obtain a free node; or the server may query each node in the network to obtain a free node, and the current seed then obtains a free node from the server, that is, the current seed queries the network through the server. Each node in the middle gets a free node. And instructing the idle node to download data B from the current seed, specifically by sending a message, signal or instruction to the idle node. In this embodiment, if node 1 and node 2 are idle nodes, node 1 and node 2 download data B from seed 1 to become a new seed. In addition, when the idle node downloads data B from the current seed, the corresponding download policy can be set. For example, the downloading strategy may be that each idle node randomly downloads various parts of the data B; the downloading strategy may also be that some idle nodes start downloading from the latter part of the data B, some idle nodes start downloading from the previous part of the data B, and the like; When downloading data B, it is not necessary to download the entire part of data B. For example, some free nodes can be set to download the first half of data B to stop downloading, and some idle nodes download the last two of data B. One part can stop downloading and so on. The download policy is not limited, and can be flexibly set according to the actual application.

Further, when the step 204 is specifically: the node requester A indicates that the current seed expands the new seed, and indicates the current seed to expand the number of new seeds, the step 205 may specifically be: the current seed receives the extended new seed and the extension. An indication of the number of new seeds; the current seed acquires an idle node, and selects from all the idle nodes obtained The idle node is to be extended, wherein the number of idle nodes to be extended is equal to the number of extended new seeds; the current seed indicates that the idle node to be extended downloads data B from the current seed; the idle node to be extended receives data downloaded from the current seed Instructed by B, downloading data B becomes a new seed. It should be noted that, in actual applications, there may be a case where the total number of available idle nodes is smaller than the number of extended new seeds, and only all idle nodes need to be selected as the idle nodes to be extended. Or in the actual application, there may be multiple current seeds selecting the same idle node as the idle node to be extended. In this case, the same idle node may be used as the idle node to be extended by any current seed of any current seed, or The same idle node may be used as the to-be-expanded idle node of the current seed that meets the preset selection condition in the current current seed, and is not specifically limited. Any other feasible allocation method may be set according to the actual application status. Moreover, when the idle node to be extended downloads the data B from the current seed, a download policy similar to that when the idle node downloads the data B from the current seed may be set.

206: The node requester A obtains the information of the new seed, and downloads the data B from the new seed and the current seed, and determines whether the total number of the current seed and the new seed is less than a preset seed number threshold, if the preset seed quantity is greater than or equal to Threshold, then stop expanding the seed, download data B from the new seed and the current seed, and end after downloading data B.

Specifically, the node requester A may acquire information of the new seed from the server; or may acquire information of the new seed from the current seed; or may acquire information of the new seed from the new seed.

It should be noted that a connection relationship is established between each node and the server. When the idle node becomes a new seed, the server knows the latest status of the node, so that the new seed information can be notified to the node requester A or the node request. A is obtained by querying the server; since the new seed is obtained by the current seed extension, the current seed can inform the node requester A or the node requester A of the new seed information by querying the current seed; or when expanding the new seed After the information of the node requester A is notified to the new seed, and the new seed obtains the information of the node requester A, the new seed directly informs the node requester A of its own information. The information of the node requester A includes information such as the identifier of the node requester A, the network type of the node requester A, and the IP address of the node requester A.

In this embodiment, the new seed is set to node 1 and node 2, so data B is downloaded from the new seed and the current seed, that is, data B is downloaded from node 1, node 2, and seed 1. Moreover, it can be known from step 205 that when the node 1 and the node 2 download the data B, the components of the data B may be randomly downloaded; or the node 1 may first download from the previous component of the data B, and the node 2 first Download from the next component of data B, and so on. This allows Node 1 and Node 2 to quickly provide Node Requester A with the components of Data B that it has not yet downloaded, speeding up the download speed of Node Requestor A. In addition, it can be seen that, in this embodiment, the total number of current seeds and new seeds is 3, and the preset seed number threshold is 2, then node requester A downloads data B from node 1, node 2, and seed 1, and downloads data B. After the end.

It should be noted that, when the judgment result of the step is that the total number of the current seed and the new seed is less than the preset seed number threshold, the original current seed and the new seed are regarded as new current seeds, and the node requester A indicates new When The pre-seed further expands the new seed. Among them, the process of further expanding the new seed by the new current seed is similar to the process of expanding the new seed by the current seed, and will not be described here. That is, when the preset seed number threshold is not reached, the new seed can be further expanded until the requirement is met, thereby ensuring the number of seeds and increasing the speed of downloading data.

207: Node requester A downloads data B from the current seed, and ends after downloading data B.
