[0038] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0039] With the development of cloud computing technology, data storage has become an important research field. In traditional public cloud storage, all files and data are often stored in the same central server. Due to the large amount of data processing, the central server has excessive network load, data transmission delays due to long-distance data transmission, and low central server management efficiency, which seriously affects the overall processing capacity and response speed of cloud computing.

[0040] In order to solve the above problems, an embodiment of the present invention provides a file management method based on a converged edge network to improve transmission efficiency and system response speed.

[0041] like Figure 1 As shown, the file management method based on the converged edge network specifically includes:

[0042] Step S1: Obtain a file management request, call a file upload interface according to the file management request, and obtain file data uploaded by a designated terminal connected to the file upload interface.

[0043] It should be noted that file management requests can be initiated through the Fusion Edge File Management Application. The Fusion Edge File Management Application provides an intuitive user interface and a simple file and folder upload operation method to help users initiate file management requests, while simplifying the file upload process and operation experience.

[0044] This embodiment pre-designs a file upload interface to ensure that the file upload interface can be accessed by clients on different operating systems and devices, such as Windows, macOS, iOS, Android, etc. The file upload interface can support the file upload requirements of various terminal devices.

[0045] It should be noted that the file management request can also be automatically generated when any terminal device accesses the file upload interface.

[0046] like Figure 2As shown, this embodiment connects the terminal device to which files need to be uploaded, such as a smart phone, PC, etc., through the file upload interface, and uploads the files or folders specified by the user through the fusion edge file management application; the system responds to the file management request to obtain the files or folders uploaded by the terminal device from the file upload interface to obtain the corresponding file data.

[0047] Step S2: Determine the target edge cloud node in the fused edge network that is closest to the geographical location of the designated terminal according to the preset fused edge network rules.

[0048] It should be noted that this embodiment pre-selects appropriate locations in the converged edge network to deploy multiple edge cloud nodes, such as in user-intensive areas, enterprise parks, near IoT devices, etc., which are geographical locations with relatively large file management requirements. In addition, a file collection service is installed and configured on each edge cloud node. The file collection service is used to receive file data uploaded from different terminals and provide storage space corresponding to the file data, while providing core functions such as file storage, data encryption, and secure transmission.

[0049] The edge network rules of this embodiment are that when receiving file data, according to the geographical location where the file data is generated, that is, the geographical location where the terminal device is located, an edge cloud node deployed near the geographical location of the terminal device is searched for file data processing. This is equivalent to traversing each edge cloud node, calculating the distance between the geographical location of each edge cloud node and the geographical location of the terminal device, and finding the closest edge cloud node between the geographical location of each edge cloud node and the geographical location of the terminal device as the target edge cloud node. By processing the file data through the target edge cloud node, the distance and time of data transmission can be reduced, thereby significantly reducing latency and improving the real-time and efficiency of data processing.

[0050] When multiple file management requests are initiated, the file data of different terminal devices are uploaded to different edge cloud nodes for processing, which is equivalent to multiple edge cloud nodes realizing distributed processing, effectively sharing the pressure of the central server and improving the overall processing capacity and response speed of the system.

[0051] Step S3: Upload the file data to the target edge cloud node, store and manage the file data based on the target edge cloud node, and obtain key data.

[0052] After determining the target cloud node, this embodiment uploads the file data uploaded by the terminal device to the target edge cloud node; during the upload process, the file data is encrypted and a secure transmission protocol is used to ensure the security of the data during transmission. Specifically, the specific method of encrypted transmission is:

[0053] Encrypt the file data based on a public key encryption algorithm to obtain encrypted data;

[0054] An encrypted transmission channel is built based on the specified encryption protocol, and the encrypted data is uploaded to the target edge cloud node through the encrypted transmission channel.

[0055] Among them, the public key encryption algorithm can use the RSA algorithm to encrypt files. RSA is an asymmetric encryption algorithm that uses a pair of keys, namely a public key and a private key. The public key can be made public and used to encrypt data; the private key must be kept secret and used to decrypt data. The public key can be distributed to any client that needs to encrypt files, while the private key is retained on the server side for decryption. In this way, even if the data is intercepted during transmission, attackers without the private key cannot decrypt the file content.

[0056] This embodiment uses the HTTPS protocol to encrypt the transmission channel to prevent eavesdropping and tampering of file data during transmission. HTTPS provides data encryption, identity authentication and data integrity through the SSL / TLS protocol based on HTTP.

[0057] After the file data is encrypted and transmitted to the target edge cloud node, the file data is initially processed and analyzed through the file collection service deployed by the target edge cloud node, which can reduce the amount of data that needs to be transmitted to the central server, thereby reducing network bandwidth consumption and related costs.

[0058] Implement file storage and management on the target edge cloud node, including file classification, indexing, backup and other functions, to facilitate subsequent data processing and analysis; file classification usually follows the natural structure of the file system, and classifies and manages the content in the storage space according to user preferences, while indexing helps locate files faster. Specifically, file storage and management of file data based on the target edge cloud node includes:

[0059] Step S31: classify the file data according to the preset classification rules to obtain classified files.

[0060] It should be noted that classification rules can be set in advance according to actual needs to meet different business needs and management goals. For example, classification can be based on file extensions, file size ranges, file creation or last modification dates, file sources or uploaders, file content themes or keywords, and file confidentiality levels or sensitive information contained.

[0061] Step S32: traverse all classification files, extract feature information of each classification file, create corresponding index entries for each classification file according to the feature information, store the index entries in an index structure, and the index structure supports query and retrieval.

[0062] Specifically, traverse each classified file after classification to determine the file attributes that need to be indexed, such as file name, extension, size, creation date, modification date, access date, owner, permissions, etc. Select a suitable data structure to store the index according to the needs, such as hash table, B-tree, inverted index, etc.

[0063] Scan each classified file, extract the feature information of each classified file, and use the extracted feature information to fill the index structure. The feature information includes file name, path, size, creation and modification time, etc.

[0064] Create an index entry for each classified file that needs to be indexed and store the index entry in an index structure, such as a hash table or B-tree.

[0065] At the same time, monitor the changes of each classified file, such as the addition, modification or deletion of files, and update the index in time according to the changes of the classified files.

[0066] Step S33: Back up and store key data according to a preset backup strategy, where the key data includes classified files and index structures.

[0067] It should be noted that the backup strategy can be set in advance according to actual needs to protect key data from unexpected situations such as hardware failure, human error, natural disasters, etc. The backup strategy includes key elements such as backup type, backup frequency, backup storage location, and data retention policy, among which:

[0068] The backup types include:

[0069] Full backup: A complete backup of all data makes recovery simple, but it takes up a lot of storage space and takes a long time to back up.

[0070] Incremental backup: Only backs up the data that has been added or modified since the last backup. It has a fast backup speed and takes up little space, but all incremental backups need to be applied in sequence when restoring.

[0071] Differential backup: backs up all new or modified data since the last full backup. The recovery speed is between full backup and incremental backup.

[0072] Mirror backup: Creates a real-time copy of data, allowing for rapid recovery of entire systems or services.

[0073] Backup frequency refers to the frequency of backup based on the importance and change frequency of the data. For example, critical business data may need to be backed up every hour, while some static data may be backed up every day or every week.

[0074] Backup storage location refers to the fact that data can be backed up to a variety of storage media, such as external hard drives, network attached storage (NAS), cloud storage, etc.

[0075] Data retention policy refers to how long data needs to be kept, which is often influenced by regulatory compliance and business needs.

[0076] Back up critical data to the target edge cloud node or other storage medium according to the backup strategy pre-set by the user, and then execute subsequent steps.

[0077] Step S4: Synchronize the key data to the central server connected to the target edge cloud node for storage according to the specified synchronization strategy.

[0078] Specifically, the synchronization strategy of this embodiment can be dynamically adjusted according to the file access frequency, specifically:

[0079] Obtaining the access log of the specified terminal, and determining the access characteristics of the file data according to the access log, the access characteristics including the number of accesses and the access time;

[0080] The access frequency of file data is determined based on the access characteristics, and the synchronization strategy is determined based on the access frequency, so that key data can be synchronized to the central server for storage according to the synchronization strategy.

[0081] For hot data with high access frequency, a more frequent synchronization strategy can be adopted, that is, the synchronization time interval is relatively short, while for cold data with low access frequency, a less frequent synchronization can be adopted, that is, the synchronization time interval can be relatively long.

[0082] In another implementation, data synchronization may be performed periodically to check source data changes at predetermined time intervals and synchronize the changes to the target system, which is suitable for scenarios where real-time requirements are not high.

[0083] By preprocessing the file data in the target edge cloud node, the data on the target edge cloud node and other edge cloud nodes are synchronized to the central server regularly to achieve long-term data preservation and further processing, such as real-time monitoring of key data corresponding to each designated terminal based on the central server, and abnormal alarm level execution when any key data is abnormal. Distributed processing of edge cloud nodes and then synchronization to the central server can reduce the amount of data that needs to be transmitted to the central server, thereby reducing network bandwidth consumption and ensuring data integrity and availability.

[0084] Furthermore, after the data is stored in the central server, users can log in to the central server to access the files with authorization, thereby achieving security and privacy protection.

[0085] Specifically, when the central server receives an access request, it determines the visitor's identity information based on the access request, authenticates the identity information, and obtains an authentication result; if the authentication result is that the authentication is passed, the visitor's access rights to the central server are determined based on the identity information.

[0086] This embodiment implements a strict access control policy, allowing only authorized users to access files, and integrates an authentication and permission management mechanism to ensure secure access to data and protect user privacy. The converged edge file management application supports multiple authentication methods, including basic credentials (user name and password). The backend manages user sessions and controls access based on defined permissions. JSON files can be used to manage user information and authentication. The permission management mechanism allows the creation of multiple user accounts with different permissions, which means that you can control who has access to specific directories on the central server and what operations they can perform. In the configuration file, you can set user permissions, such as admin, execute, create, rename, modify, delete, share, and download permissions under the perm field. These permissions define the user's ability to operate files and directories.

[0087] Assuming that a large manufacturing enterprise needs to collect production data and surveillance videos between multiple factories for real-time analysis and quality control, the file management method based on the converged edge network of this embodiment is described in this usage scenario:

[0088] like Figure 3 As shown, edge cloud node deployment means deploying edge cloud nodes in each factory in advance, equipped with high-performance computing and storage devices; and installing file collection services in the edge cloud nodes deployed in each factory, including components such as data encryption, secure transmission, and file storage management.

[0089] Client application development: Develop client applications for factory equipment (such as surveillance cameras, sensors, etc.) to realize the automatic file upload function. Develop mobile applications for factory managers, allowing them to view and manage uploaded files through mobile devices. Factory equipment (such as surveillance cameras, sensors, etc.) can interact with the fusion edge file management application through its own device management platform, and store, collect and manage device data through the file collection function.

[0090] File collection and management: Configure the file collection service of the edge cloud node to automatically collect data and video files uploaded by factory equipment. Implement file classification, indexing, and backup functions in the edge cloud node to facilitate rapid retrieval and analysis of data for a specific time period or a specific production line; and regularly synchronize key data and video files in the production process to the central server for long-term storage and further analysis. Different edge cloud nodes process file data uploaded by different factory equipment, and then synchronize them to the central server for centralized management, realizing cross-factory data integration and real-time monitoring.

[0091] At the same time, security and privacy protection implements strict data encryption and transmission security policies to ensure the security of data during upload and synchronization. Integrate multi-factor authentication mechanisms to ensure that only authorized users can access sensitive data. Comply with relevant data protection regulations to ensure user privacy and data security.

The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc.

[0098] Optionally, in a specific implementation, if the memory 100, the processor 200 and the communication interface 300 are integrated on a chip, the memory 100, the processor 200 and the communication interface 300 can communicate with each other through an internal interface.
