It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

The source storage device is only one, and the number of target storage devices can be multiple. The data storage system can store data required to be processed by the server 106. The data storage system can be integrated on the server 106, or placed on the cloud or other network servers. The source storage device 102 and the target storage device 104 can be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things device can be a smart speaker, a smart television, a smart air conditioner, a smart vehicle device, a projection device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 106 can be a stand-alone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0047] In an exemplary embodiment, as shown in Figure 2 A file transmission method is provided. Taking the source storage device 102 in Figure 1 as an example, the method includes the following steps 202 to 204. Wherein:

[0048] Step 202, receiving a file uploaded by a terminal in a connection established with the terminal; wherein the source storage device is selected from multiple storage devices by a scheduling device according to the usage state of each storage device; the usage state includes at least one of load or available space.

[0049] In some embodiments, the connection with the terminal is established, and the file uploaded by the terminal, i.e., the file to be synchronized, is received.

[0050] Further, the source storage device is a storage device selected by a scheduling server on the scheduling device according to the usage state of each storage device. The usage state includes at least one of the load or available space of the storage device; the load refers to the workload or burden borne by the storage device.

[0051] Step 204, verifying the file, and storing the file that passes the verification; wherein the storage mode includes direct storage or block storage.

[0052] In some embodiments, the source storage device will verify the file to be synchronized, and store the file that passes the verification to the local database.

[0053] In the storage process, the entire file can be stored completely or the file can be stored in blocks according to specific storage requirements.

[0054] In the file transmission method, the file uploaded by the terminal is received in the case of establishing a connection with the terminal. The source storage device is selected from a plurality of storage devices by the scheduling device according to the usage state of each storage device. The usage state includes at least one of the load or the available space. The file is verified, and the file that passes the verification is stored. The storage mode includes direct storage or block storage. In this way, the source storage device is selected from a plurality of storage devices, and the encrypted synchronization of the file between multiple terminals is realized through a distributed architecture, effectively improving the efficiency and security of the low-code application synchronization file process.

[0055] In an exemplary embodiment, the file transmission method further comprises: adding the file to the synchronization queue; in the case of meeting the file synchronization condition, sending the content in the synchronization queue to the target storage device to instruct the target storage device to synchronize the storage of the corresponding content, and returning a synchronization confirmation message; the file synchronization condition includes that the file is changed or the current needs to perform a delayed file synchronization task, the file change includes storing a newly uploaded file, and the content in the synchronization queue includes the file and the file change information; receiving the synchronization confirmation message, updating the synchronization state record, and sending the synchronization state record to the scheduling device.

[0056] In actual implementation, after receiving the synchronization file, the source storage device stores the synchronization file and the metadata information of the synchronization file in the local database according to the preset rules. After the storage is completed, the synchronization file is added to the synchronization queue. When the file upload is completed, the file is modified, or the file needs to be synchronized, the content in the synchronization queue is sent to the target storage device to instruct the target storage device to synchronize the storage of the corresponding content, and a synchronization confirmation message is returned. The metadata information includes the file name, size, type, storage path, and a series of information related to the synchronization file. The content in the synchronization queue includes the synchronization file, the metadata information of the synchronization file, and the change information of the synchronization file.

[0057] Further, the source storage device receives the synchronization confirmation message, updates the synchronization state record, and sends the synchronization state record to the scheduling device.

[0058] In the above embodiment, by synchronizing the file of the source storage device to the target storage device in real time, the repeated work and errors caused by inconsistent files are reduced, and the work efficiency is improved.

[0059] In some example embodiments, the file transmission method further comprises: sending a connection detection message to the target storage device in the process of file synchronization with the target storage device; in the case that a connection normal message returned by the target storage device for the connection detection message is not received, interrupting the file synchronization process between the source storage device and the target storage device, and recording interruption information; reselecting a target storage device from the remaining storage devices, and performing file synchronization with the reselected target storage device.

[0060] In actual implementation, the source storage device sends a connection detection message to the target storage device every interval of a preset time in the process of file synchronization with the target storage device. When a connection normal message returned by the target storage device for the connection detection message is not received, the file synchronization process between the source storage device and the target storage device is interrupted, and interruption information is recorded. The interruption information can be information related to subsequent continuous transmission, such as the transmission progress of the file, and the example embodiments of the present application do not limit this.

[0061] For example, the file interruption can be caused by network failure or the like.

[0062] Further, the file synchronization with the remaining target is continued.

[0063] In the above example embodiments, the continuity and reliability of the synchronization process are ensured by uninterrupted connection normal confirmation between the source storage device and the target storage device.

[0064] In some example embodiments, the file transmission method further comprises: in the case that the connection between the source storage device and the target storage device corresponding to the interruption information is restored, resuming the execution of the corresponding file synchronization process based on the interruption information.

[0065] In actual implementation, when the source storage device is restored to the target storage device corresponding to the interruption information, the synchronization process of the corresponding target storage device is continued based on the recorded interruption information.

[0066] In the above example embodiments, the source storage device continues to synchronize files on the corresponding target storage device in the case of interruption recovery, thereby ensuring the integrity of the entire synchronization process.

[0067] In some example embodiments, the file transmission method comprises: receiving content sent by a source storage device based on a synchronization queue, and synchronizing the corresponding content; wherein the synchronization process is initiated by the source storage device based on file synchronization conditions; the file synchronization conditions include file change or current need to perform a delayed file synchronization task, the file change includes storage of newly uploaded files, and the content in the synchronization queue includes files and file change information; returning a synchronization confirmation message to the source storage device, the synchronization confirmation message being used to instruct the source storage device to update a synchronization state record, and sending the synchronization state record to a scheduling device.

[0068] In actual implementation, the target storage device receives the content sent by the source storage device based on the synchronization queue, and synchronously stores the corresponding content. After the storage is completed, a synchronization confirmation message is returned to the source storage device, which is used to instruct the source storage device to update the synchronization state record and send the synchronization state record to the scheduling device.

[0069] In the above embodiment, the content sent by the source storage device based on the synchronization queue is received, and the corresponding content is synchronously stored; wherein the synchronization process is initiated by the source storage device based on a file synchronization condition; the file synchronization condition includes that a file is changed or a delay file synchronization task needs to be performed at present, the file is changed includes that a newly uploaded file is stored, and the content in the synchronization queue includes a file and file change information; a synchronization confirmation message is returned to the source storage device, which is used to instruct the source storage device to update the synchronization state record and send the synchronization state record to the scheduling device. In this way, the encryption synchronization of the file between multiple target storage devices is realized through a distributed architecture, and the efficiency and security of the low-code application synchronization file process are effectively improved.

[0070] In some exemplary embodiments, the file transmission method further includes: in the process of file synchronization with the source storage device, receiving a connection detection message sent by the source storage device; in the case that the connection between the source storage device is normal, returning a connection normal message to the source storage device, the connection normal message being used to instruct the source storage device to continue to perform the file synchronization process; in the case that the connection between the source storage device is abnormal, resulting in that the source storage device does not receive the connection normal message, the file synchronization process between the source storage device is interrupted.

[0071] In actual implementation, the target storage device receives a connection detection message sent by the source storage device in the process of file synchronization with the source storage device; in the case that the connection between the source storage device is normal, a connection normal message is returned to the source storage device. In the case that the connection between the source storage device is abnormal, resulting in that the source storage device does not receive the connection normal message, the file synchronization process between the target storage device and the source storage device is interrupted.

[0072] In the above embodiment, the connection detection information sent by the source storage device is received every preset time, and the fault is discovered and processed in time.

[0073] In some exemplary embodiments, the file transmission method includes: updating the synchronously stored content to the local file system and the database.

[0074] In some embodiments, when the target storage device receives the synchronously stored content, the synchronously stored content is updated to the local file system and the database.

[0075] In the above embodiments, by storing the synchronized content to the database local to the target storage device, it is more convenient to call when the target storage device needs to use the synchronized file.

[0076] In some exemplary embodiments, the above file transmission method can also be applied to a terminal, and a specific file uploading process is shown in Figure 3 .

[0077] Exemplarily, the terminal obtains a file to be uploaded in response to a file uploading operation. The terminal sends a file uploading request to a scheduling device to instruct the scheduling server to determine IP address and port information of a storage server as an uploading target.

[0078] The terminal receives IP address and port information of the source storage device returned by the scheduling device, establishes a connection with the source storage device according to the IP address and port information, uploads the file to the source storage device to instruct the source storage device to store the file and generate a corresponding file identifier, and receives the file identifier returned by the source storage device when the source storage device successfully stores the file.

[0079] In some embodiments, the above file transmission method can also be applied to the scheduling device.

[0080] Exemplarily, the scheduling device receives a file uploading request sent by a terminal. The scheduling device selects a source storage device from a plurality of storage devices according to a usage state of each storage device, the usage state including at least one of a load or available space. The scheduling device sends corresponding IP address and port information of the source storage device to the terminal to instruct the terminal to establish a connection with the source storage device and send a file to be uploaded to the source storage device for file uploading.

[0081] To describe the file transmission method in the present application in detail, an embodiment is described below. Exemplarily, the present application describes a file transmission method in a specific file transmission scenario.

[0082] First, the terminal obtains a file to be uploaded in response to a file uploading operation. The terminal sends a file uploading request to a scheduling device to instruct the scheduling server to determine IP address and port information of a storage server as an uploading target.

[0083] The scheduling device receives a file uploading request sent by a terminal. The scheduling device selects a source storage device from a plurality of storage devices according to a usage state of each storage device, the usage state including at least one of a load or available space. The scheduling device sends corresponding IP address and port information of the source storage device to the terminal to instruct the terminal to establish a connection with the source storage device and send a file to be uploaded to the source storage device for file uploading.

[0084] receive the IP address and port information of the source storage device returned by the scheduling device, establish a connection with the source storage device according to the IP address and port information, upload the file to the source storage device to instruct the source storage device to store the file, and generate a corresponding file identifier; when the source storage device successfully stores the file, receive the file identifier returned by the source storage device.

[0085] The specific synchronization process is shown in FIG. 2. After receiving the synchronization file, the source storage device stores the synchronization file and the metadata information of the synchronization file in the local database according to a preset rule. After the storage is completed, the synchronization file is added to the synchronization queue. When the file uploading is completed, the file is modified, or the synchronization file needs to be delayed, the content in the synchronization queue is sent to the target storage device to instruct the target storage device to synchronously store the corresponding content, and a synchronization confirmation message is returned. Figure 4

[0086] Further, the source storage device receives the synchronization confirmation message, updates the synchronization state record, and sends the synchronization state record to the scheduling device.

[0087] During the file synchronization process between the source storage device and the target storage device, the source storage device sends a connection detection message to the target storage device at a preset interval. When no connection normal message returned by the target storage device for the connection detection message is received, the file synchronization process between the source storage device and the target storage device is interrupted, and interruption information is recorded, and the file synchronization process with the remaining target is continued.

[0088] When the source storage device recovers the target storage device corresponding to the interruption information, the source storage device continues to perform the synchronization process of the corresponding target storage device according to the recorded interruption information.

[0089] The target storage device receives the content sent by the source storage device based on the synchronization queue, and synchronously stores the corresponding content. After the storage is completed, a synchronization confirmation message is returned to the source storage device. The synchronization confirmation message is used to instruct the source storage device to update the synchronization state record, and send the synchronization state record to the scheduling device.

[0090] During the file synchronization process between the source storage device and the target storage device, the target storage device receives the connection detection message sent by the source storage device; in the case that the connection between the source storage device and the target storage device is normal, a connection normal message is returned to the source storage device. In the case that the connection between the source storage device and the target storage device is abnormal, resulting in that the source storage device does not receive the connection normal message, it is indicated that the file synchronization process between the source storage device and the target storage device is interrupted.

[0091] When the target storage device receives the synchronously stored content, the target storage device updates the synchronously stored content to the local file system and the database. ​

[0092] The present application optimizes system performance by intelligently selecting a synchronization strategy, such as real-time synchronization, timed synchronization, or on-demand synchronization, according to various factors.

[0093] By constructing an efficient, flexible, and reliable architecture, real-time, accurate, and secure synchronization of files between multiple terminals is achieved. Users can perform file operations on multiple terminals without worrying about information leakage in the files, effectively improving the operation experience and security of low-code applications.
