[0028] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description. It should be noted that the embodiments in the present disclosure and the features in the embodiments may be combined with each other without conflict.

[0029] It should be pointed out that in the technical solution of the present invention, the collection, acquisition, storage, processing, transmission, provision, disclosure and application of user personal information (such as file sharing records, etc.) are all carried out with the user's knowledge and explicit authorization, comply with the relevant laws and regulations, and do not violate public order and good morals.

[0030] Figure 1 An exemplary system architecture 100 is shown to which embodiments of the image update scheme of the present disclosure may be applied.

[0031] like Figure 1 As shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104 and servers 105, 106, 107. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105, and between the server 105, the server 106 and the server 107. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc. In the embodiment of the present disclosure, the server 105 may be a centralized server 105, the server 106 may be a computer room server 106, and the server 107 may be a cloud device server 107.

[0032] Users can use terminal devices 101, 102, 103 to interact with the centralized server 105, computer room server 106, and cloud device server 107 through network 104 to receive or send messages, etc. Various applications for realizing information communication between the terminal devices 101, 102, 103 and the centralized server 105, computer room server 106, and cloud device server 107 can be installed, such as image update applications, cloud computing service applications, cloud mobile phone service applications, etc.

[0033] The terminal devices 101, 102, 103 and the centralized server 105, the computer room server 106, and the cloud device server 107 can be hardware or software. When the terminal devices 101, 102, and 103 are hardware, they can be various electronic devices with display screens, including but not limited to smart phones, tablet computers, laptop portable computers, and desktop computers, etc.; when the terminal devices 101, 102, and 103 are software, they can be installed in the electronic devices listed above, which can be implemented as multiple software or software modules, or as a single software or software module, and no specific limitation is made here. When the centralized server 105, the computer room server 106, and the cloud device server 107 are hardware, they can be implemented as a distributed server cluster composed of multiple servers, or as a single server; when the server is software, it can be implemented as multiple software or software modules, or as a single software or software module, and no specific limitation is made here.

[0034] The centralized server 105, the computer room server 106, and the cloud device server 107 can provide various services through various built-in applications. For example, the centralized server 105 can provide image update-related applications. When running the image update-related applications, the centralized server 105 can achieve the following effects: when receiving an image update task to be executed, the centralized server 105 can determine the target file corresponding to the image update task, and determine an adaptive or appropriate download mode, i.e., a target download mode, for the corresponding target file from a plurality of candidate download modes, and can send the target download mode to the computer room server 106 through an image update message. Further, the computer room server 106 can 106 can timely forward the image update message to the cloud device server 107, so that the cloud device server 107 can timely respond to execute the download operation of the target file corresponding to the image update task, wherein the image update message at least includes the indication information of the target download mode of the target file corresponding to the image update task, which is determined from multiple candidate download modes. In this way, by flexibly and adaptively screening out the target download mode that matches the current image update task to be executed from multiple candidate download modes, it is beneficial to improve the efficiency of the download operation for the target file, thereby improving the success rate and efficiency of the image update and improving the user experience. Among them, the centralized server 105 can be a server cluster that manages each computer room server 106.

[0035] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0036] Please refer to Figure 2 , Figure 2 The flowchart of an image update method provided by an embodiment of the present disclosure is executed by an execution subject centralized server, wherein the process 200 includes the following steps:

[0037] Step 201: In response to receiving an image update task to be executed, obtaining a target file corresponding to the image update task.

[0038] This step is intended to be performed by the above-mentioned execution subject of the image update method (for example Figure 1 The server 105 and Figure 6 The centralized server 602 based on the Platform as a Service (PaaS) platform shown in FIG. 6 receives the data from the user through the user terminal (in a specific application scenario, it may correspond to Figure 6The image update task to be executed (in a specific application scenario, it may correspond to Figure 6 The process 6-1 shown, initiates a custom image update task through the PaaS platform), and obtains the corresponding target file of the image update to be executed in response to the received image update task to be executed; wherein, the target file includes but is not limited to one or more of the files corresponding to the basic software package, the files corresponding to the custom software package, and the files corresponding to the resource package, depending on the specific image update task, which is not specifically limited here.

[0039] Step 202: Determine a target download mode corresponding to the target file from multiple candidate download modes.

[0040] On the basis of step 201, this step aims to enable the execution subject to match a suitable download mode, namely, a target download mode, for the target file corresponding to the current image update task to be executed from a plurality of candidate download modes.

[0041] Step 203: Send an image update message corresponding to the image update task to the computer room server; wherein the image update message includes indication information of the target download mode.

[0042] The image update method provided by the embodiment of the present disclosure can determine the target file corresponding to the image update task when receiving the image update task to be executed, and determine an adaptive or suitable download mode, namely the target download mode, for the corresponding target file from multiple candidate download modes, and can send the target download mode to the computer room server through the image update message, so as to forward it to the cloud device server through the computer room server. In this way, the target download mode that matches the current image update task to be executed can be flexibly and adaptively screened out from the multiple candidate download modes, which is conducive to improving the efficiency of the download operation for the target file, thereby improving the success rate and efficiency of the image update and improving the user experience.

[0043] In a specific application scenario, such as Figure 6As shown, an image update process 600 supporting the transmission between boards in a server is executed by an image update system including a user terminal 601, a centralized server based on a cloud phone PaaS platform (referred to as PaaS-centralized server) 602, a computer room server based on a PaaS platform (referred to as PaaS-computer room server) 603, and a device proxy server 604 (corresponding to a cloud device server), wherein the PaaS-centralized server 602 includes a distribution service module 6021, a task module 6022, and a scheduled task module 6023, and the PaaS-computer room server 603 includes a message queue 6031 and a computer room bastion service module 6032. In the image update process 600, the distribution service module 6021 responds to the image update task initiated by the user terminal 601, and can send the saved task information to the task module 6022 through process 6-2; the task module 6022 can scan the image update task to be executed from the scheduled task module 6023 through process 6-3. Then the scheduled task module 6023 can check and judge the image update mode through process 6-4, that is, the image update mode corresponding to the image update task can be determined, which can include the Advanced RISC Machine (ARM) mode or the computer language instruction set (X86) mode executed by the microprocessor, wherein the file storage forms corresponding to different image update modes are different, for example, in the ARM mode, the files to be updated (i.e., target files) composed of the basic software package and the custom software package can be sent in the form of multiple files, while in the x86 mode, the files to be updated can be sent in the form of a whole package (e.g., a compressed package), that is, the mode needs to be obtained first to further determine the number and size of the files actually needed to be downloaded. Further, the scheduled task module 6023 can obtain the file information that needs to be downloaded by all physical machines that need to be updated in batches this time through process 6-5. Further, the scheduled task module 6023 sends the image update message to the message queue through process 6-6.

[0044] In the above Figure 2 On the basis of the corresponding embodiments, the above-mentioned multiple candidate download modes include but are not limited to a download mode based on the File Transfer Protocol (FTP), a download mode based on the Hypertext Transfer Protocol (HTTP), and a download mode based on the Simple Storage Service (S3). In this way, by providing multiple download modes for flexible selection to implement file download, the connection number bottleneck of the device to be updated can be avoided due to a single download mode, thereby helping to reduce the pressure of file download or transmission in concurrent scenarios.

[0045] Furthermore, in the above Figure 2 Based on the corresponding embodiments, the target download mode may be one of a download mode based on a file transfer protocol, a download mode based on a hypertext transfer protocol, and a download mode based on a simple storage service protocol.

[0046] In the above Figure 2 On the basis of the corresponding embodiments, some optional implementation methods of the embodiments of the present disclosure may also include the following contents: in response to the size of the target file being greater than or equal to a preset threshold, segmenting the target file to obtain at least two segment files; in response to receiving download requests sent by the cloud device server for at least two segment files respectively, sending first download addresses corresponding to at least two segment files respectively to the computer room server; wherein the first download address corresponds to the target download mode.

[0047] In this embodiment, it can be determined whether to segment the target file based on the size relationship between the target file corresponding to the currently executed mirror update task and a preset threshold, and further, when the size of the target file is greater than or equal to the preset threshold, the target file can be segmented into at least two segment files, which can effectively reduce the pressure of file downloading or transmission; and when a download request sent by a cloud device server for each segment file is received, in order to ensure that the segment file can be downloaded efficiently, each segment file corresponding to the target download mode determined from a plurality of candidate download modes can be sent to the computer room server respectively corresponding to the first download address, so that it can be forwarded to the cloud device server in a timely manner through the computer room server, thereby ensuring the efficiency of file downloading or transmission.

[0048] It should be noted that the value of the above preset threshold can be set according to the specific situation of the image update task to be executed, and is not specifically limited here.

[0049] Furthermore, in some optional implementations of the embodiments of the present disclosure, the image update message further includes information indicating the number of at least two shards. Thus, by indicating the number of shard files obtained after sharding the target file in the image update message, it is helpful to accurately and efficiently request downloads and provide download address feedback for each shard file, thereby improving the efficiency of image updates.

[0050] It should be noted that in some optional implementations of the embodiments of the present disclosure, in response to the size of the target file being smaller than the preset threshold, quantity indication information indicating that the number of fragment files of the target file is one can be carried in the above-mentioned image update message. In this way, the request download and download address feedback of the entire target file can be realized at one time.

[0051] Furthermore, in some optional implementations of the embodiments of the present disclosure, the image update message may also include, but is not limited to, at least one of the following: identification information of the image update task, the Internet Protocol (IP) address of the physical machine on which the target file to be downloaded is mounted on the board, the Internet Protocol IP address of the cloud phone on which the image update is required to be performed is mounted on the physical machine, and the timeout of the image update task. The timeout of the image update task may refer to the time within which the image update task needs to be completed.

[0052] Furthermore, in some optional implementations of the embodiments of the present disclosure, the following contents may also be included: receiving update notification messages respectively sent by the computer room server for at least two segmented files; wherein the update notification message is sent by the computer room server in response to a download completion notification message sent by the cloud device server for the segmented file, and the download completion notification message and the update notification message respectively include a second download address corresponding to the segmented file; in response to the received update notification message, updating the download status identifier corresponding to the segmented file, and recording the second download address corresponding to the segmented file; wherein the download status identifier is used to indicate whether the segmented file has been downloaded.

[0053] In this embodiment, the download status of each of the at least two segment files can be maintained. Specifically, when receiving the update notification message fed back by the computer room server in response to the download completion notification message sent by the cloud device server for each segment file, the download status identifier of each segment file can be updated, for example, from the identifier "not downloaded" to "downloaded or downloaded"; at the same time, the second download address corresponding to each segment file obtained can also be recorded. In this way, it is helpful to summarize, check and / or analyze the download status of each segment file.

[0054] Furthermore, in some optional implementations of the embodiments of the present disclosure, the above-mentioned second download addresses may refer to board download addresses (such as ARM backplane download addresses) of the sliced ​​files that correspond one-to-one to each first download address, or download addresses where the physical machine saves the sliced ​​files locally.

[0055] Furthermore, in some optional implementations of the embodiments of the present disclosure, the following contents may also be included: in response to confirming that at least two segment files have been downloaded, all second download addresses corresponding to the at least two segment files are obtained from the computer room server; in response to obtaining all second download addresses, a download success message for the at least two segment files is sent to the computer room server; wherein the download success message is used to indicate a merge operation to be performed on the at least two downloaded segment files.

[0056] Among them, it can be determined whether the download status identifier corresponding to each segment file in the above-mentioned at least two segment files indicates that the corresponding segment file has been downloaded. If so, it can be confirmed that at least two segment files have been downloaded, that is, all segment files obtained by segmenting the target file have been downloaded.

[0057] In this embodiment, when it is confirmed that all the segment files corresponding to the target file have been downloaded, all the second download addresses corresponding to all the segment files can be uniformly obtained from the computer room server, and after obtaining all the second download addresses, an indication message that all the segment files have been successfully downloaded, i.e., a download success message, is further triggered to be fed back to the computer room server, so as to trigger the merging of all the successfully downloaded segment files, thereby ensuring the smooth completion of the image update.

[0058] The above process of obtaining all the second download addresses corresponding to at least two shard files from the server in the computer room in response to confirming that at least two shard files have been downloaded can include: sending a request to the server in the computer room in response to confirming that at least two shard files have been downloaded; receiving all the second download addresses corresponding to the at least two shard files fed back by the server in the computer room in response to the request. In this way, when it is confirmed that all the shard files corresponding to the target file have been downloaded, the acquisition of all the second download addresses corresponding to all the shard files can be actively triggered, so as to timely know the download addresses corresponding to the shard files on the local cloud device server.

[0059] Continue to use the above specific application scenario as an example to explain the specification. Figure 6 As shown, the scheduled task module 6023 can obtain the file information that needs to be downloaded by all physical machines that need to be batch updated this time through process 6-5 to obtain the size of the files that need to be downloaded (i.e., the files to be updated in the image, which may include basic software packages, custom software packages, and resource packages), and after filtering duplicate files, determine whether to perform dynamic segmentation based on the size of the files to be downloaded. Specifically, when the size of the file to be downloaded is greater than or equal to a certain threshold, it is segmented. The image update of process 6-8 can be divided into two branches. If the device proxy server 604 determines that there are still segments that need to be downloaded, processes 6-8-1 to 6-8-7 are repeated; if the device proxy server 604 determines that there are no segments that need to be downloaded, processes 6-8-8 to 6-8-11 are executed, as follows:

[0060] Process 6-8-1: The device proxy server 604 obtains the download address of the next segment file (corresponding to the first download address), such as an FTP / HTTP / S3 protocol address, from the distribution service module 6021 of the PaaS-centralized server 602.

[0061] Process 6-8-2: The distribution service module 6021 of the PaaS-centralized server 602 returns data including the download address of the segmented file requested by the device proxy server 604 to the computer room bastion server service module 6032 of the PaaS-computer room server.

[0062] Process 6-8-3: The computer room bastion machine service module 6032 of the PaaS-computer room server sends the download address of the shard file and the coordinates of the shard file to the device proxy server 604.

[0063] Process 6-8-4: The device proxy server 604 downloads the segment file according to the download address of the segment file.

[0064] Process 6-8-5: The device proxy server 604 sends a notification message of completion of the segment file download to the computer room bastion machine service module 6032 of the PaaS-computer room server.

[0065] Process 6-8-6: The server room bastion service module 6032 of the PaaS-server room considers concurrency issues and joins the callback memory queue.

[0066] Process 6-8-7: The computer room bastion machine service module 6032 asynchronously calls back the distribution service module 6021 of the PaaS-centralized server 602 to update the download status of the segmented file and record the ARM baseboard download address (corresponding to the second download address).

[0067] Process 6-8-8: The distribution service module 6021 of the PaaS-centralized server 602 obtains the ARM backplane download address of all downloaded segment files from the computer room bastion machine service module 6032 of the PaaS-computer room server.

[0068] Process 6-8-9: The distribution service module 6021 of the PaaS-centralized server 602 returns data to the computer room bastion server service module 6032 of the PaaS-computer room server, and returns a message that all the shard files have been downloaded successfully.

[0069] Process 6-8-10: The computer room bastion machine service module 6032 of the PaaS-computer room server forwards the message that all the segment files have been downloaded successfully to the device proxy server 604.

[0070] Process 6-8-11: Merge each fragment file according to the coordinates of the fragment files corresponding to each of the fragment files.

[0071] Please refer to Figure 3 , Figure 3 The flowchart of an image updating method provided by an embodiment of the present disclosure is executed by an execution subject computer room server, wherein process 300 includes the following steps:

[0072] Step 301: receiving an image update message corresponding to an image update task to be executed sent by a centralized server; wherein the image update message includes indication information of a target download mode corresponding to a target file, the target file corresponds to the image update task, and the target download mode is one of multiple candidate download modes.

[0073] This step is intended to be performed by the above-mentioned execution subject of the image update method (for example Figure 1 The server 106 shown in the figure receives an image update message corresponding to the image update task currently to be executed, which is sent by the centralized server. The image update message may include at least indication information of a target download mode of a target file corresponding to the image update task, which is determined from multiple candidate download modes; wherein the target file includes but is not limited to one or more of a file corresponding to a basic software package, a file corresponding to a custom software package, and a file corresponding to a resource package, depending on the specific image update task, and is not specifically limited here.

[0074] Step 302: Send an image update message to the cloud device server.

[0075] The image update method provided by the embodiment of the present disclosure can forward the image update message corresponding to the image update task to be executed to the cloud device server in a timely manner upon receiving the image update message corresponding to the image update task to be executed, wherein the image update message at least includes the indication information of the target download mode of the target file corresponding to the image update task, which is determined from multiple candidate download modes. In this way, by flexibly and adaptively screening out the target download mode that matches the current image update task to be executed from the multiple candidate download modes, it is beneficial to improve the efficiency of the download operation for the target file, thereby improving the success rate and efficiency of the image update and enhancing the user experience.

[0076] In the above Figure 3 Based on the corresponding embodiments, the above-mentioned multiple candidate download modes include but are not limited to a download mode based on the file transfer protocol, a download mode based on the hypertext transfer protocol, and a download mode based on the simple storage service protocol. In this way, by providing multiple download modes for flexible selection to implement file download, the connection number bottleneck of the device to be updated can be avoided due to a single download mode, thereby helping to reduce the pressure of file download or transmission in concurrent scenarios.

[0077] Furthermore, in the above Figure 3 Based on the corresponding embodiments, the target download mode may be one of a download mode based on a file transfer protocol, a download mode based on a hypertext transfer protocol, and a download mode based on a simple storage service protocol.

[0078] In the above Figure 3On the basis of the corresponding embodiments, in some optional implementation methods of the embodiments of the present disclosure, when the size of the above-mentioned target file is greater than or equal to a preset threshold and is fragmented and processed by the centralized server into at least two fragment files, the mirror update method of the above-mentioned embodiments of the present disclosure may further include the following contents: sending first download addresses corresponding to at least two fragment files to the cloud device server; wherein, the first download addresses corresponding to at least two fragment files are sent by the centralized server in response to download requests sent by the cloud device server for at least two fragment files, and the first download addresses correspond to the target download mode.

[0079] In this embodiment, when the target file corresponding to the currently to-be-executed image update task is fragmented into at least two fragment files, the download addresses of each fragment file requested by the cloud device server as fed back by the centralized server and corresponding to the target download mode, i.e., the first download address, can be promptly forwarded to the cloud device server, thereby effectively reducing the pressure of file downloading or transmission and improving the efficiency of file downloading or transmission.

In this way, it is helpful to summarize, check and / or analyze the download status of the respective shard files.

[0084] Furthermore, in some optional implementations of the embodiments of the present disclosure, the above-mentioned second download addresses may refer to board download addresses (such as ARM backplane download addresses) of the sliced ​​files that correspond one-to-one to each first download address, or download addresses where the physical machine saves the sliced ​​files locally.

[0087] Furthermore, in some optional implementation methods of the embodiments of the present disclosure, the following contents may also be included: sending the fragment coordinates corresponding to at least two fragment files respectively to the cloud device server; wherein, all the fragment coordinates corresponding to the at least two fragment files are used to indicate the order in which the cloud device server performs the merge operation on the at least two downloaded fragment files.

[0090] Please refer to Figure 4 , Figure 4 This is a flowchart of an image update method provided by an embodiment of the present disclosure. The image update method is executed by an execution subject, a cloud device server, wherein process 400 includes the following steps:

[0091] Step 401: receiving an image update message corresponding to an image update task to be executed sent by a computer room server; wherein the image update message includes indication information of a target download mode corresponding to a target file, the target file corresponds to the image update task, and the target download mode is one of multiple candidate download modes.

[0092] This step is intended to be performed by the above-mentioned execution subject of the image update method (for example Figure 1 The server 107 shown receives an image update message corresponding to the image update task to be executed currently forwarded by the computer room server, and the image update message may include at least indication information of the target download mode of the target file corresponding to the image update task and determined from multiple candidate download modes; wherein the target file includes but is not limited to one or more of the files corresponding to the basic software package, the files corresponding to the custom software package, and the files corresponding to the resource package, depending on the specific image update task, which is not specifically limited here.

[0093] Step 402: In response to the received mirror image update message, a download operation for the target file is performed.

[0094] The image update method provided by the embodiment of the present disclosure can respond in a timely manner to execute a download operation of a target file corresponding to the image update task to be executed upon receiving an image update message corresponding to the image update task to be executed, wherein the image update message at least includes indication information of a target download mode of the target file corresponding to the image update task, which is determined from multiple candidate download modes. In this way, by flexibly and adaptively screening out a target download mode that matches the current image update task to be executed from multiple candidate download modes, it is beneficial to improve the efficiency of the download operation for the target file, thereby improving the success rate and efficiency of the image update and enhancing the user experience.

[0095] In the above Figure 4 Based on the corresponding embodiments, the above-mentioned multiple candidate download modes include but are not limited to a download mode based on the file transfer protocol, a download mode based on the hypertext transfer protocol, and a download mode based on the simple storage service protocol. In this way, by providing multiple download modes for flexible selection to implement file download, the connection number bottleneck of the device to be updated can be avoided due to a single download mode, thereby helping to reduce the pressure of file download or transmission in concurrent scenarios.

[0096] Furthermore, in the above Figure 4 Based on the corresponding embodiments, the target download mode may be one of a download mode based on a file transfer protocol, a download mode based on a hypertext transfer protocol, and a download mode based on a simple storage service protocol.

[0097] In the above Figure 4 On the basis of the corresponding embodiments, in some optional implementations of the embodiments of the present disclosure, when the size of the target file is greater than or equal to a preset threshold and is fragmented by the centralized server into at least two fragmented files, the download operation for the target file in step 402 of the image update method in the above embodiment of the present disclosure may further include the following contents:

[0098] In response to completing the download operation of the first segment file among the at least two segment files, sending a download request for the second segment file among the at least two segment files to the centralized server; in response to receiving the first download address corresponding to the second segment file, performing a download operation on the second segment file; wherein the download request corresponding to the first segment file is located before the download request corresponding to the second segment file in terms of sending timing, and the second segment file is one of the segment files that have not been downloaded among the at least two segment files.

[0099] In this embodiment, when the target file is processed by slicing to obtain at least two slicing files for download, the download mode of requesting the download address one by one and downloading them one by one is followed. Specifically, when the download operation of the previous slicing file, i.e., the first slicing file, is completed, the centralized server is requested for the first download address of the next slicing file that has not been downloaded, i.e., the second slicing file, until all slicing files are downloaded, so as to ensure that all slicing files can be downloaded accurately, avoid omissions, and cause incomplete downloaded files, thereby affecting the efficiency of image update. The first slicing file and the second slicing file mentioned above can refer to two slicing files in the at least two slicing files that are adjacent in the request timing of the download address.

[0100] Furthermore, in some optional implementations of the embodiments of the present disclosure, performing a download operation on the above-mentioned second segment file may specifically include: determining whether the second segment file is downloaded by other physical machines other than the first physical machine mounted on the first board; in response to the second segment file not being downloaded by other physical machines, performing a download operation on the second segment file by the first physical machine according to the first download address corresponding to the second segment.

[0101] In this embodiment, considering that each board can be mounted on multiple physical machines and each physical machine can be mounted on a cloud phone, then all physical machines mounted on the board need to download all segment files corresponding to the target file to perform an image update. When downloading each segment file, in order to avoid the physical machine on the same board from repeatedly downloading the same segment file and reduce the pressure of file downloading or transmission, before each physical machine downloads each segment file, it is possible to confirm whether the board to which it currently belongs already has a corresponding downloaded segment file. If so, there is no need to download it repeatedly, especially in high-concurrency scenarios, when multiple physical machines use the same image file for update at the same time, repeated downloading of the same file can be avoided.

[0102] Furthermore, in some optional implementations of the embodiments of the present disclosure, the image update message further includes information indicating the number of at least two shards. Thus, the number of shard files obtained after the target file indicated in the image update message is processed by sharding helps to accurately and efficiently request downloads and provide download address feedback for each shard file, thereby improving the efficiency of image updates.

[0103] Furthermore, in some optional implementations of the embodiments of the present disclosure, the image update message may also include, but is not limited to, at least one of the following: identification information of the image update task, the Internet Protocol IP address of the physical machine on which the target file to be downloaded is mounted on the board, the Internet Protocol IP address of the cloud phone on which the image update is required to be performed is mounted on the physical machine, and the timeout of the image update task.

[0104] Furthermore, in some optional implementations of the embodiments of the present disclosure, the following content may also be included: calling an idle second board to perform a download operation on a third shard file among at least two shard files. In this way, by calling other idle second boards except the first board to which the physical machine to which the download operation is to be performed on the current shard file, i.e., the third shard file, belongs, to perform a download operation on the current shard file, the download efficiency of each shard file corresponding to the target file of the image update task to be performed can be further improved, the resource utilization rate can be improved, and thus the efficiency of the image update can be improved.

[0105] Furthermore, in some optional implementations of the embodiments of the present disclosure, the following contents may also be included: in response to the completion of the download operation on the second segment file, a download completion notification message corresponding to the second segment file is sent to the computer room server; wherein the download completion notification message includes a second download address corresponding to the second segment file.

[0106] In this embodiment, after each download operation on one of the at least two segment files corresponding to the target file is completed, a download completion notification message corresponding to the downloaded segment file, i.e., the second segment file, can be sent to the computer room server, and the second download address corresponding to the segment file can be fed back through the download completion notification message, so as to timely feed back the download completion status of each segment file.

[0107] Furthermore, in some optional implementations of the embodiments of the present disclosure, the above-mentioned second download addresses may refer to board download addresses of the sliced ​​files (such as ARM backplane download addresses) that correspond one-to-one to each first download address, or download addresses where the physical machine saves the sliced ​​files locally.

[0108] Furthermore, in some optional implementations of the embodiments of the present disclosure, the following contents may also be included: in response to receiving a download success message for at least two segment files sent by a computer room server, performing a merging operation on the at least two downloaded segment files; wherein the download success message is sent by the centralized server to the computer room server in response to confirming that the download of at least two segment files has been completed and obtaining all second download addresses corresponding to the at least two segment files.

[0109] In this embodiment, when a download success message is received confirming that all segment files corresponding to the target file have been downloaded, a merge operation can be performed on at least two segment files corresponding to the downloaded target file in a timely manner, thereby ensuring smooth completion of the image update.

[0110] Furthermore, in some optional implementations of the embodiments of the present disclosure, the following contents may also be included: receiving slice coordinates corresponding to at least two slice files respectively sent by the computer room server; and performing a merge operation on the at least two downloaded slice files, including: performing a merge operation on the at least two downloaded slice files according to the order indicated by all slice coordinates corresponding to the at least two slice files.

[0111] In this embodiment, in order to efficiently complete the merging operation of all downloaded shard files to ensure the success rate and efficiency of the image update, the merging operation of the shard files can be performed on all downloaded shard files in an order indicated by all shard coordinates corresponding to the at least two shard files received from the computer room server, so as to efficiently and orderly complete the merging operation of the shard files.

[0112] Further, in some optional implementations of the embodiments of the present disclosure, the first download addresses and the slice coordinates corresponding to the above-mentioned respective slice files may be received together from the server in the computer room. The slice coordinates may be represented by a number that can distinguish the order, such as being identified in the form of a preset number of positive integers arranged from small to large, wherein the value of the preset number is the same as the value of the number of at least two slice files; or in the form of "Xn", wherein X may represent the identifier of the package to which each slice file belongs that constitutes the above-mentioned target file, and n may represent the file sequence number of each slice file in the package to which it belongs, wherein the values ​​of X and n may be positive integers respectively.
