[0062] 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.

[0063] 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.

[0064] BitTorrent is a protocol and technology for large-scale file sharing, which allows users to share files in a distributed manner, thereby reducing the burden on the server and increasing the download speed. However, in some cases, the download speed of existing BitTorrent download technology may be affected by the health of the seed and the quality of the peer node connection, resulting in slow download speed and download failure.

[0065] Therefore, in order to overcome the above 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 through a bitstream seed cluster, and downloading the second data block through a content distribution network acceleration node cluster, assembling the first data block and the second data block to obtain a downloaded file; since the present application downloads file data through the bitstream seed cluster and the content distribution network acceleration node cluster at the same time, it can utilize the acceleration advantage of the content distribution network node to improve the download speed and stability, thereby improving the user experience.

[0066] 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.

[0067] Based on this, the present application embodiment provides a file download method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for downloading documents of this application.

[0068] In a first embodiment, the file downloading method includes:

[0069] 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.

[0070] It should be understood that in order to make full use of resources from different sources to improve download efficiency and download success rate, 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.

[0071] In a specific implementation, when a user initiates a file download request, the data to be downloaded can be divided into multiple data blocks based on factors such as file size, network conditions, and download strategy, and then the multiple data blocks can be divided into first data blocks and second data blocks based on peer node information of the bitstream seed cluster and content distribution network node information of the content distribution network acceleration node cluster.

[0072] Further, in order to improve the accuracy of identifying the file to be downloaded, the step S10 includes: in response to a file download request, obtaining a seed file corresponding to the file download request; parsing the seed file to obtain the file to be downloaded; dividing the data to be downloaded corresponding to the file to be downloaded into a first data block and a second data block. The seed file may refer to a small file containing file information (such as file name, size, hash value, index and location of file fragments, etc.), which can be used in the BitTorrent protocol so that users can download and share large files.

[0073] In a specific implementation, when a user initiates a file download request through a client or browser, the request can be identified and the corresponding seed file can be located (for example, the user has provided a link to the seed file or directly opened the seed file in the client). The seed file is parsed using the BitTorrent protocol or related tools to extract information about the file to be downloaded, such as the file name, size, hash value, and index and location of the file fragments.

[0074] Step S20: downloading the first data block through a bitstream seed cluster, and downloading the second data block through a content distribution network acceleration node cluster.

[0075] It is understandable that in order to make full use of the advantages of the two technologies, an efficient and stable file download service is achieved. In this embodiment, the first data block is downloaded through a bitstream seed cluster, and the second data block is downloaded through a content distribution network acceleration node cluster. Among them, the bitstream seed cluster may refer to a distributed download network based on the BitTorrent protocol, which is composed of multiple nodes, and these nodes jointly provide a piecemeal download service for the file. Each node has a portion of the data of the file and can share this data with other nodes. The content distribution network acceleration node cluster may refer to a distributed network architecture, consisting of multiple geographically dispersed nodes. These nodes cache the content of the original server and distribute the content to the node closest to the user based on the user's geographical location and network conditions to improve download speed and user experience.

[0076] In the specific implementation, the first data block is downloaded through the BitTorrent seed cluster, because the BitTorrent protocol is suitable for distributed download of large-scale files and can make full use of idle resources in the network. For the second data block, the CDN acceleration node cluster is used to download, because CDN can significantly increase the download speed and reduce latency, especially for large-volume, high-concurrency download scenarios.

[0077] Step S30: Assemble the first data block and the second data block to obtain a download completion file.

[0078] It should be understood 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.

[0079] 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.

[0080] For ease of understanding, refer to Figure 2 This invention is provided for illustration, but is not intended to limit the present application. Figure 2 This is an interactive diagram of an embodiment of the method for downloading application documents. Figure 2 In the example, it is assumed that the data to be downloaded of the file to be downloaded is divided into 9 data blocks, data blocks 1, 2 and 3 are divided into the first data block, and data blocks 4, 5, 6, 7, 8 and 9 are divided into the second data block. The first data block is downloaded through the BitTorrent seed cluster, and the second data block is downloaded through the CDN acceleration node cluster. After the first data block and the second data block are downloaded, the first data block and the second data block are reassembled according to the original order of the file to form a complete download file.

[0081] This embodiment downloads file data through the bitstream seed cluster and the content distribution network acceleration node cluster at the same time, thereby being able to utilize the acceleration advantage of the content distribution network nodes to improve the download speed and stability, thereby being able to enhance the user experience.

[0082] Furthermore, in order to ensure that the data blocks are correctly placed in the file, the step S30 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] It can be understood that verifying the filled data block to obtain the verified data block can be by comparing the hash value of the filled data block with the hash value of the seed file corresponding to the file download request; verifying the filled data block according to the comparison result to obtain the verified data block.

[0087] Furthermore, in order to facilitate the user to understand the download progress and results and avoid unnecessary waste of resources, after step S30, 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. Among them, the download completion notification may refer to a notification or prompt information displayed to the user by the client or browser after the user completes the file download. Temporary files may refer to some files created during the download process for storing part of the downloaded data or temporary data.

[0088] 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.

[0089] Reference Figure 3 , Figure 3 This is a flow chart of the second embodiment of the method for downloading application files. Figure 1 The first embodiment shown proposes a second embodiment of the method for downloading files of the present application.

[0090] In the second embodiment, the step S20 includes:

[0091] Step S201: select a peer node from a bitstream seed cluster, and download the first data block through the peer node.

[0092] It should be noted that a peer node may refer to a node in a bittorrent seed cluster that provides file segment download services and is also a client that downloads segments provided by other nodes.

[0093] It should be understood that selecting a peer node from the bitstream seed cluster and downloading the first data block through the peer node may be to match the data to be downloaded with the download data of the node in the bitstream seed cluster; selecting a peer node from the bitstream seed cluster based on the matching result, and downloading the first data block through the peer node.

[0094] In a specific implementation, in a BitTorrent seed cluster, multiple peer nodes can be searched and connected to, and these peer nodes have part or all of the data of the file that the user wishes to download. Then, one or more of the peer nodes can be selected to download the first data block.

[0095] Step S202: Select a content distribution network node from the content distribution network acceleration node cluster, and download the second data block through the content distribution network node.

[0096] It should be noted that a content delivery network node may refer to a single node in a CDN node cluster, which is responsible for caching and distributing specific content to improve the download or access speed of users.

[0097] In a specific implementation, the CDN node cluster may be composed of multiple geographically dispersed nodes, each of which caches a copy or fragment of the file. One or more nodes may be selected from the CDN node cluster to download the second data block according to the user's geographical location and network conditions.

[0098] This embodiment selects a peer node from a bitstream seed cluster and downloads the first data block through the peer node, selects a content distribution network node from a content distribution network acceleration node cluster, and downloads the second data block through the content distribution network node, thereby further improving the download speed of the data block.

[0099] 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.

[0100] In the third embodiment, the step S202 includes:

[0101] Step S2021: Create an independent thread.

[0102] 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.

[0103] Step S2022: selecting a content distribution network node from the content distribution network acceleration node cluster through the independent thread, and downloading the second data block through the content distribution network node.

[0104] It is understandable that after the independent thread is created, the independent thread is responsible for selecting a CDN node from the CDN node cluster and downloading the second data block through the CDN node. The process of selecting a CDN node can be based on various factors, such as node availability, download speed, geographical location, and distance from the user, etc., which are not limited in this embodiment.

[0105] This embodiment creates an independent thread and performs CDN download through the independent thread, thereby maintaining the smoothness of the CDN download process.

[0106] Furthermore, in order to improve the download speed and efficiency, in this embodiment, the optimal CDN node can be selected based on the CDN node information to download the data block, and the step S2022 includes: requesting the content distribution network node information corresponding to the file to be downloaded from the content distribution network service through the independent thread; selecting a content distribution network node from the content distribution network acceleration node cluster based on the content distribution network node information. Among them, the content distribution network service can be a system that provides content distribution network (CDN) acceleration services, and 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.

[0107] It can be understood that selecting a content distribution network node from a content distribution network acceleration node cluster based on content distribution network node information can be to parse the content distribution network node information to obtain node address information and node availability; and select a content distribution network node from a content distribution network acceleration node cluster based on the node address information and node availability.

[0108] For ease of understanding, refer to Figure 2 This invention is provided for illustration, but is not intended to limit the present application. Figure 2 This is an interactive diagram of an embodiment of the method for downloading application documents. Figure 2 In the method for downloading a file, the steps include:

[0109] 1. Start file download: The user launches the BitTorrent client and adds the seed file to start downloading the file.

[0110] 2. Data block division: divide the data to be downloaded of the file to be downloaded into 9 data blocks, divide data blocks 1, 2 and 3 into first data blocks, and divide data blocks 4, 5, 6, 7, 8 and 9 into second data blocks.

[0111] 3. Start a separate thread to request CDN service: Start a separate thread to request CDN service for CDN node information of the file to be downloaded.

[0112] 4. Get CDN node information: Get CDN acceleration node information about the file to be downloaded from the CDN service, including the node address and availability.

[0113] 5. Request block data: According to the CDN node information, send requests to each CDN node in turn to obtain the block data of the file.

[0114] 6. Filling data blocks: Fill the file with the first data block and the second data block obtained from different sources (BitTorrent protocol and CDN service) in different orders.

[0115] 7. Data verification: Verify each data block to ensure the integrity and correctness of the data.

[0116] 8. File assembly: Assemble all filled data blocks into a complete file in the correct order.

[0117] 9. Complete download: After the download is complete, perform necessary processing to ensure that the file has been completely downloaded and is available
