[0063] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0064] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0065] Currently, in browsers, downloading files of the Hypertext Transfer Protocol (HTTP) type is an important function and a scenario that users use frequently. The existing file download method is usually to download separately through the browser's network process, and the download speed is limited. However, with the development of the Internet, the quality of video and film information has also been greatly improved, and the size of the file has also become very large. Therefore, the existing file download method has the defects of slow download speed and poor user experience.

[0066] Therefore, in order to overcome the above-mentioned defects, the present application provides a solution, which includes: in response to a file download request, dividing the data to be downloaded corresponding to the file to be downloaded into a first data block and a second data block, downloading the first data block from the original download site corresponding to the file to be downloaded through the original acceleration node cluster, downloading the second data block from other data sources through the intelligent acceleration node cluster, wherein the other data source is a data source other than the original download site, assembling the first data block and the second data block to obtain a downloaded file; since in the present application a part of the data blocks are downloaded from the original download site through the original acceleration node cluster, and another part of the data blocks are downloaded from other data sources through the intelligent acceleration node cluster, the file download speed can be increased, thereby improving the user experience.

[0067] It should be noted that the execution subject of this embodiment can be a file downloading device with data processing, network communication and program running functions, such as a computer, or other electronic devices that can achieve the same or similar functions, and this embodiment does not impose any restrictions on this.

[0068] Based on this, the present application embodiment provides a file download method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the method for downloading documents of this application.

[0069] In a first embodiment, the file downloading method includes:

[0070] Step S10: In response to the file download request, divide the to-be-downloaded data corresponding to the to-be-downloaded file into a first data block and a second data block.

[0071] It should be understood that in order to make full use of resources from different sources to improve the download speed, in this embodiment, in response to a file download request, the data to be downloaded corresponding to the file to be downloaded is divided into a first data block and a second data block. Among them, the file download request may refer to an instruction initiated by a user through a client or a browser to obtain a specific file from a server or a network. The file to be downloaded may refer to a target file that the user wants to download, which may be any type of file such as a movie, music, or a document. The data to be downloaded may refer to all data contents contained in the file to be downloaded, and these data may be divided into multiple data blocks during the download process for easy transmission and processing. The first data block may refer to the first part of the data to be downloaded after being divided, and the first data block may include multiple data blocks. The second data block may refer to the second part of the data to be downloaded after being divided, and together with the first data block, it constitutes a complete file to be downloaded, and the second data block may also include multiple data blocks.

[0072] In a specific implementation, when a user initiates a file download request (such as an HTTP request), the data to be downloaded can be divided into multiple data blocks (such as dividing a file into multiple data blocks according to a 1M size) according to factors such as the file size, network conditions, and download strategy, and then the multiple data blocks can be divided into a first data block and a second data block according to a preset strategy. The preset strategy can be pre-set, and this embodiment does not limit this.

[0073] Step S20: downloading the first data block from the original download site corresponding to the file to be downloaded through the original acceleration node cluster.

[0074] It is understandable that in order to ensure the reliability of the source of the data block and to improve the download efficiency by utilizing the performance advantage of the acceleration node. In this embodiment, the first data block is downloaded from the original download site corresponding to the file to be downloaded by the original acceleration node cluster. The original acceleration node cluster may refer to a group of servers or nodes specifically used to obtain data from the original download site. The original download site may be the original server or site that provides the file to be downloaded.

[0075] In a specific implementation, an HTTP request is sent to an original download site through a server or a node of the original acceleration node cluster to download the first data block from the original download site.

[0076] Step S30: downloading the second data block from other data sources through the intelligent acceleration node cluster, wherein the other data sources are data sources other than the original download site.

[0077] It should be understood that in order to utilize diverse data sources and increase the download speed. In this embodiment, the second data block is also downloaded from other data sources through an intelligent acceleration node cluster. Among them, the intelligent acceleration node cluster can refer to a group of servers or nodes that can intelligently select the optimal download path according to network conditions and data sources. Other data sources can be any source that can provide file data to be downloaded other than the original download site, such as a peer-to-peer (P2P) network, a content delivery network (CDN) node, a local memory, etc., which is not limited in this embodiment.

[0078] In a specific implementation, the intelligent selection capability of the intelligent acceleration node cluster is utilized to request and download the second data block from other data sources other than the original download site (such as other users in the P2P network, CDN nodes, etc.).

[0079] Step S40: Assemble the first data block and the second data block to obtain a download completion file.

[0080] It is understandable that in order to ensure the integrity and correctness of the file, in this embodiment, the first data block and the second data block are assembled to obtain a download completion file, wherein the download completion file may refer to a complete file formed after all the data blocks to be downloaded are successfully downloaded and correctly assembled.

[0081] In a specific implementation, after the first data block and the second data block are downloaded, the first data block and the second data block can be reassembled according to the original order of the file to form a complete download completed file.

[0082] In this embodiment, a portion of data blocks are downloaded from the original download site through the original acceleration node cluster, and another portion of data blocks are downloaded from other data sources through the intelligent acceleration node cluster, thereby increasing the file download speed and further improving the user experience.

[0083] Furthermore, in order to ensure that the data blocks are correctly placed in the file, the step S40 includes: filling the first data block and the second data block into the file to be downloaded to obtain filled data blocks; assembling the filled data blocks in a preset order to obtain a downloaded file. The preset order may refer to a specific order in which the data blocks are assembled into a complete file during the file assembly process, which may be consistent with the storage order of the file on the disk.

[0084] In a specific implementation, during the download process, data blocks may be continuously received. Once a data block is downloaded, the data block is filled into the corresponding position of the file to be downloaded. After all data blocks are downloaded and filled into the file, the data blocks may be assembled into a complete file in a preset order.

[0085] Furthermore, in order to timely discover and correct errors in data blocks and avoid using erroneous data for file assembly, the filled data blocks are assembled in a preset order to obtain the downloaded file, including: verifying the filled data blocks to obtain data blocks that pass the verification; assembling the data blocks that pass the verification in a preset order to obtain the downloaded file. The data blocks that pass the verification may refer to data blocks that have been verified and confirmed to be correct.

[0086] In a specific implementation, after the data filling is completed, each data block can be verified. The verification method can include hash verification, cyclic redundancy check (CRC) verification, etc. to ensure the integrity and correctness of the data. The data blocks that have been verified and confirmed to be correct are used for subsequent file assembly. After all data blocks are downloaded and verified, the data blocks are assembled into a complete file in a preset order.

[0087] It can be understood that verifying the filled data block to obtain the verified data block can be by comparing the data characteristics of the filled data block with the data characteristics of the file to be downloaded; verifying the filled data block according to the comparison result to obtain the verified data block.

[0088] Furthermore, in order to facilitate users to understand the download progress and results and avoid unnecessary waste of resources, after step S40, it also includes: generating a download completion notification corresponding to the download completion file and displaying the download completion notification; obtaining a temporary file corresponding to the download completion file and cleaning up the temporary file.

[0089] In a specific implementation, after the file assembly is completed, the client or browser can generate a download completion notification and display the notification to the user through the user interface. The notification can include information such as the file name, size, and download completion time. During the download process, some files are created to store part of the downloaded data or temporary data. These temporary files are usually no longer needed after the download is completed, so they can be cleaned up to avoid unnecessary waste of resources.

[0090] Reference Figure 2 , Figure 2 This is a flow chart of the second embodiment of the method for downloading application files. Figure 1The first embodiment shown proposes a second embodiment of the method for downloading files of the present application.

[0091] In the second embodiment, the step S30 includes:

[0092] Step S301: selecting a download acceleration method through an intelligent acceleration node cluster, wherein the download acceleration method includes at least one of peer-to-peer network acceleration, content distribution network acceleration, and mirror acceleration.

[0093] It should be understood that in order to achieve dynamic optimization and improve download speed, in this embodiment, the intelligent acceleration node cluster can intelligently select the download acceleration method, and request and download the second data block from the corresponding data source according to the download acceleration method selected by the intelligent acceleration node cluster.

[0094] It should be noted that peer-to-peer acceleration (P2P acceleration) may refer to a technology that uses the downloaded data of other users in the network to accelerate the download process. Content distribution network acceleration (CDN acceleration) may refer to a technology that accelerates content distribution and downloading through CDN nodes distributed in various places. Mirror acceleration may refer to a technology that uses a mirror server that stores the same file to accelerate downloading.

[0095] In the specific implementation, the intelligent acceleration node cluster intelligently selects the optimal download acceleration method based on factors such as current network conditions, availability of data sources, and load conditions.

[0096] Step S302: downloading the second data block from the corresponding data source based on the download acceleration method.

[0097] It is understandable that in order to fully utilize the advantages of various acceleration methods and improve the download speed, in this embodiment, the second data block is downloaded from the corresponding data source based on the download acceleration method. In a specific implementation, for example, according to the download acceleration method selected by the intelligent acceleration node cluster, the second data block is requested and downloaded from the corresponding data source.

[0098] This embodiment uses an intelligent acceleration node cluster to intelligently select a download acceleration method, and requests and downloads the second data block from a corresponding data source according to the download acceleration method selected by the intelligent acceleration node cluster, thereby achieving dynamic optimization and improving the download speed.

[0099] Furthermore, in order to utilize the resources of other users in the network to accelerate downloading and reduce the dependence on the original server and bandwidth consumption, the download acceleration method is peer-to-peer network acceleration; the step S302 includes: obtaining the current download data of each node in the peer-to-peer network, and matching the data to be downloaded with the current download data of each node; selecting a peer node from the peer-to-peer network according to the matching result, and downloading the first data block through the peer node. The peer node may refer to a node that provides data to other users in peer-to-peer network acceleration.

[0100] In a specific implementation, if a certain peer node has downloaded a portion of the data of the second data block, the smart acceleration node cluster can guide other users to download this portion of data from the peer node.

[0101] Furthermore, in order to utilize the distributed characteristics of the CDN network to improve the download speed, the download acceleration method is content distribution network acceleration; the step S302 includes: requesting a content distribution network acceleration node; downloading the second data block through the content distribution network acceleration node. The content distribution network acceleration node may refer to a specific server node in the CDN network, which is responsible for storing and distributing content.

[0102] Furthermore, in order to maintain the smoothness of the CDN download process, the request for the content distribution network acceleration node includes: creating an independent thread, and requesting the content distribution network node information corresponding to the file to be downloaded from the content distribution network service through the independent thread; and selecting a content distribution network node based on the content distribution network node information.

[0103] It should be understood that in order to maintain the smoothness of the CDN download process, in this embodiment, an independent thread can be created and CDN download can be performed through the independent thread. The independent thread can refer to a thread in a computer program that can independently execute tasks, which does not share the execution path with the main thread or other threads, but can share the resources of the process.

[0104] It is understandable that after the independent thread is created, the independent thread is responsible for selecting a CDN node from the CDN network and downloading the second data block through the CDN node. The process of selecting a CDN node can be based on a variety of factors, such as the availability of the node, the download speed, the geographical location, and the distance from the user, etc., which are not limited in this embodiment. Among them, the content distribution network service can be a system that provides a content distribution network (CDN) acceleration service, which realizes rapid distribution and transmission of data by deploying multiple nodes. Content distribution network node information can refer to detailed information about each node in the content distribution network, including the address, status, load, etc. of the node.

[0105] Furthermore, in order to utilize the fast data access provided by the mirror server to increase the download speed, the download acceleration method is mirror acceleration; the step S302 includes: searching in the backend service whether there is a target file identical to the file to be downloaded; obtaining the mirror address of the target file, and downloading the second data block through the mirror address. Among them, mirror acceleration can refer to accelerating the download using a mirror server with the same content as the original server, and the mirror server can be located in different geographical locations to provide faster data access speed. The target file can refer to a file with the same content as the file to be downloaded, and can be located on a mirror server or other storage location. The mirror address can point to the URL or network location of the target file, which is used to download data from the mirror server.

[0106] In a specific implementation, it is searched in the backend service whether there is a target file identical to the file to be downloaded, the mirror address of the target file is obtained, and the second data block is downloaded from the mirror server through the mirror address.

[0107] It should be understood that in order to further improve the download speed, in this embodiment, the download acceleration method may include peer-to-peer network acceleration, content distribution network acceleration and mirror acceleration, and the step S302 includes: accelerating the download of the first part of the data blocks in the second data block through the peer-to-peer network, accelerating the download of the second part of the data blocks in the second data block through the content distribution network, and accelerating the download of the third part of the data blocks in the second data block through the mirror. The specific download process of each acceleration method is as described above and will not be repeated here.

[0108] For ease of understanding, refer to Figure 3 This invention is provided for illustration, but is not intended to limit the present application. Figure 3 This is an interactive diagram of an embodiment of the method for downloading application documents. Figure 3 In the method for downloading a file, the steps include:

[0109] 1. Start file downloading: The user initiates a file download request (such as an HTTP request) through a browser to determine the file to be downloaded.

[0110] 2. Divide the file into 1M blocks: Divide the file into 1M blocks and determine the number of blocks. For example, divide the data to be downloaded into 9 blocks, divide blocks 1, 2 and 3 into the first block, and divide blocks 4, 5, 6, 7, 8 and 9 into the second block.

[0111] 3. Request data blocks from different block sources:

[0112] (1) The source of the first data block: the original site.

[0113] Specific steps: Start 10 threads and download different block data from the original site at the same time.

[0114] (2) The source of the first part of the data block in the second data block: P2P / P2SP acceleration.

[0115] Specific steps: Use the client that is currently downloading the file as the seed end and pull the downloaded block data of the seed.

[0116] (3) Source of the second part of the data block in the second data block: CDN acceleration.

[0117] Specific steps: start a separate thread, request the server's CDN acceleration node through the Transmission Control Protocol (TCP) protocol, and pull the CDN block data.

[0118] (4) The source of the third data block in the second data block: mirror acceleration.

[0119] Specific steps: Query the mirror address of the same file in the backend service. Obtain the file data corresponding to the mirror address through HTTP request.

[0120] 4. Download block data: Obtain block data from different block sources in turn to ensure that all blocks of the file are downloaded.

[0121] 5. Merge block data: merge all downloaded block data into a complete file in sequence.

[0122] 6. Complete the download: After the download is complete, perform necessary verification and processing to ensure the integrity and correctness of the file.

[0123] Through the above method, multiple resources can be effectively utilized, including original sites, P2P acceleration, CDN services and backend service storage, to improve the efficiency and speed of file downloading.

[0124] Reference Figure 4 , Figure 4 This is a flow chart of the third embodiment of the method for downloading files of the present application. Based on the above embodiments, the third embodiment of the method for downloading files of the present application is proposed.

[0125] In the second embodiment, the step S20 includes:

[0126] Step S201: select multiple original acceleration nodes from the original acceleration node cluster, and construct a download thread corresponding to each original acceleration node.

[0127] It should be understood that in order to further improve the download speed, in this embodiment, the first data block can be downloaded by requesting data in blocks and multiple threads. The original acceleration node can refer to a specific server or node in the original acceleration node cluster. The download thread can refer to an independent execution path or process for executing a download task in computer programming.

[0128] Step S202: downloading the first data block from the original download site corresponding to the file to be downloaded through multiple download threads based on the multiple original acceleration nodes.

[0129] In a specific implementation, in order to increase the download speed, multiple original acceleration nodes may be selected from the original acceleration node cluster, and a download thread may be created for each original acceleration node. The first data block may be downloaded in parallel from the multiple original acceleration nodes through the created download threads.

[0130] This embodiment downloads the first data block by using a block-by-block multi-threaded data request method, thereby further improving the download speed.

[0131] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method for downloading the documents of the present application.
