Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, and in particular to a file synchronization method and device, electronic equipment and storage medium. BACKGROUND

[0002] In a wireless local area network (WLAN) hierarchical networking deployed with one central access controller (Central AC) and multiple local access controllers (Local ACs), as the hardware configuration of an access point (AP) is gradually improved, the ability of the AP to process services is also continuously improved. Therefore, some designated services (for example, unified communication and collaboration (UCC) services, etc.) are usually transferred from the Central AC to the AP, so that the Central AC can focus more on network management functions, thereby reducing the workload of the Central AC and improving the access rate of wireless terminals.

[0003] Currently, an administrator usually manually configures a file for each AP on the Central AC, and inputs a corresponding file synchronization instruction for each AP on the Central AC. The Central AC synchronizes the corresponding file to the corresponding AP through the corresponding Local AC. However, in the case where a large number of APs (for example, thousands or even tens of thousands of APs) are deployed in the WLAN hierarchical networking, using this file synchronization method is relatively complex to operate, and occupies a large amount of processing resources of the Central AC. SUMMARY

[0004] To overcome the problems in the related art, the present application provides a file synchronization method and device, electronic equipment and storage medium.

[0006] receiving a file synchronization instruction input by an administrator, wherein the file synchronization instruction is used to instruct the Central AC to synchronize a target file corresponding to a target service to a target AP deployed with the target service;

[0007] sending a first file synchronization message carrying the target file corresponding to the target service, the target file name corresponding to the target file and the target file signature to a target Local AC accessing the target AP, so that the target Local AC judges whether the target file name is stored locally after receiving the first file synchronization message; if the judgment result is no, the target Local AC stores all contents carried in the first file synchronization message, and sends a first file synchronization request carrying the target file name and the target file signature to the target AP accessing itself; if the judgment result is yes, the target Local AC compares the file signature corresponding to the target file name stored locally with the target file signature; if the comparison result is consistent, the target Local AC executes the step of sending the first file synchronization request carrying the target file name and the target file signature to the target AP accessing itself; if the comparison result is inconsistent, the target Local AC updates the file corresponding to the target file name stored locally to the target file, updates the file signature corresponding to the target file name stored locally to the target file signature, and executes the step of sending the first file synchronization request carrying the target file name and the target file signature to the target AP accessing itself, so that the corresponding target AP judges whether the target file name is stored locally after receiving the first file synchronization request; if the judgment result is no, the corresponding target AP stores all contents carried in the first file synchronization request, and acquires and stores the target file from the corresponding target Local AC; if the judgment result is yes, the corresponding target AP compares the file signature corresponding to the target file name stored locally with the target file signature; if the comparison result is consistent, the corresponding target Local AC is informed that file synchronization is not needed; if the comparison result is inconsistent, the corresponding target Local AC updates the file corresponding to the target file name stored locally to the target file, and updates the file signature corresponding to the target file name stored locally to the target file signature.

[0012] If the result of the judgment is yes, whether the file signature corresponding to the target file name stored locally is consistent with the target file signature is compared.

[0013] If the comparison result is consistent, the step of sending the first file synchronization request carrying the target file name and the target file signature to the target AP connected to the Central AC is performed.

[0014] If the comparison result is inconsistent, the file corresponding to the target file name stored locally is updated to the target file, the file signature corresponding to the target file name stored locally is updated to the target file signature, and the step of sending the first file synchronization request carrying the target file name and the target file signature to the target AP connected to the Central AC is performed, so that the corresponding target AP judges whether the target file name is stored locally after receiving the first file synchronization request. If the result of the judgment is no, all the contents carried in the first file synchronization request are stored, and the target file is obtained and stored from the corresponding target Local AC. If the result of the judgment is yes, whether the file signature corresponding to the target file name stored locally is consistent with the target file signature is compared. If the comparison result is consistent, the corresponding target Local AC is notified that file synchronization is not needed. If the comparison result is inconsistent, the file corresponding to the target file name stored locally is updated to the target file, and the file signature corresponding to the target file name stored locally is updated to the target file signature.

In this way, the processing resources on the Central AC side are greatly reduced, and compared with the existing synchronization process, the operation process is relatively simple and has good applicability.

[0039] Next, the embodiments of the present application are described in detail.

[0040] The embodiments of the present application provide a file synchronization method, which is applied to a Central AC, as shown in the following table, the method can comprise the following steps: Figure 1

[0041] S11, receiving a file synchronization instruction input by an administrator.

[0042] In this step, the file synchronization instruction is used to instruct the Central AC to synchronize a target file corresponding to a target service to a target AP on which the target service is deployed.

[0043] Here, the target file corresponding to the target service can be an initial file corresponding to the target service, or an updated file corresponding to the target service.

[0044] ​S12, the target Local AC corresponding to the target AP access sends a first file synchronization message carrying a target file corresponding to the target service, a target file name corresponding to the target file and a target file signature, so that the target Local AC judges whether the local storage has the target file name when receiving the first file synchronization message; if the judgment result is no, stores all the contents carried in the first file synchronization message, and sends a first file synchronization request carrying the target file name and the target file signature to the target AP accessed to itself; if the judgment result is yes, compares the file signature corresponding to the target file name stored locally with the target file signature; if the comparison result is consistent, the step of sending the first file synchronization request carrying the target file name and the target file signature to the target AP accessed to itself is executed; if the comparison result is inconsistent, the file corresponding to the target file name stored locally is updated to the target file, the file signature corresponding to the target file name stored locally is updated to the target file signature, and the step of sending the first file synchronization request carrying the target file name and the target file signature to the target AP accessed to itself is executed, so that the local storage of the target file name is judged by the corresponding target AP; if the judgment result is no, all the contents carried in the first file synchronization request are stored, and the target file is obtained and stored from the corresponding target Local AC; if the judgment result is yes, the file signature corresponding to the target file name stored locally is compared with the target file signature; if the comparison result is consistent, the corresponding target Local AC is notified that file synchronization is not needed; if the comparison result is inconsistent, the file corresponding to the target file name stored locally is updated to the target file, and the file signature corresponding to the target file name stored locally is updated to the target file signature.

[0045] It should be noted that in this step, the Central AC can specifically send the first file synchronization message carrying the target file, the target file name corresponding to the target file and the target file signature to the target AP accessed to the target Local AC through the management channel between the Central AC and the target Local AC.

[0046] Here, the target file name can be obtained by the Central AC from the file synchronization instruction; the target file can be obtained by the Central AC from the local according to the file name; and the target file signature can be obtained by the Central AC by calculating the target file according to a preset algorithm. For example, the preset algorithm can be MD5 message-digest algorithm (MD5 Message-Digest Algorithm) and the like.

[0047] In addition to carrying the target file, the target file name corresponding to the target file and the target file signature, the first file synchronization message can also carry file size (which can be calculated by the Central AC) and other information.

[0048] In addition, in this step, the target file signature of the target service is carried in the first file synchronization message, which can ensure the integrity of the related file and facilitate the corresponding Local AC and the corresponding AP to know whether the content of the file corresponding to the same file name has changed in time.

[0049] It should be further explained that in the embodiment of the present application, the target Local AC can send the first file synchronization request to the corresponding target AP through a wireless access point control and supply (Controlling and Provisioning of Wireless Access Point, CAPWAP) tunnel established with the corresponding target AP.

[0050] Further, in the embodiment of the present application, the Central AC can also perform the following operations:

[0051] After monitoring that the target Local AC re-establishes connection with itself, a second file synchronization message carrying the latest file corresponding to the target service, the target file name corresponding to the latest file and the latest file signature is sent to the target Local AC, so that the target Local AC judges whether the local storage has the target file name when receiving the second file synchronization message; if the judgment result is no, all the contents carried in the second file synchronization message are stored, and a second file synchronization request carrying the target file name and the latest file signature is sent to the target AP accessed to itself; if the judgment result is yes, whether the file signature corresponding to the target file name stored in the local storage is consistent with the latest file signature is compared; if the comparison result is consistent, the step of sending the second file synchronization request carrying the target file name and the latest file signature to the target AP accessed to itself is executed; if the comparison result is inconsistent, the file corresponding to the target file name stored in the local storage is updated to the latest file, the file signature corresponding to the target file name stored in the local storage is updated to the latest file signature, and the step of sending the second file synchronization request carrying the target file name and the latest file signature to the target AP accessed to itself is executed, so that the local storage of the target AP is judged by the corresponding target Local AC; if the judgment result is no, all the contents carried in the second file synchronization request are stored, and the latest file is acquired and stored from the corresponding target Local AC; if the judgment result is yes, whether the file signature corresponding to the target file name stored in the local storage is consistent with the latest file signature is compared; if the comparison result is consistent, the corresponding target Local AC is informed that file synchronization is not needed; if the comparison result is inconsistent, the file corresponding to the target file name stored in the local storage is updated to the latest file, and the file signature corresponding to the target file name stored in the local storage is updated to the latest file signature.

[0052] It should be noted that, in the embodiment of the present application, for the target Local AC, when the file corresponding to the target file signature or the latest file signature is acquired, a file acquisition request carrying the signature can be sent to the Central AC, and the corresponding file can be acquired from the file acquisition response sent by the Central AC.

[0053] Similarly, for the target AP, when the file corresponding to the target file signature or the latest file signature is acquired, a file acquisition request carrying the corresponding signature can be sent to the corresponding target Local AC, and the corresponding file can be acquired from the file acquisition response sent by the Central AC.

[0054] It should be further noted that in the embodiments of this application, there may be a variety of reasons that cause the target Local AC to re-establish a connection with the Central AC. For example, it may be due to a failure in the WLAN hierarchical network where the Central AC is located, or it may be due to an anomaly in the Central AC or the target Local AC. Regardless of the reason, once the Central AC detects that the target Local AC has re-established a connection with itself, it will execute the above operation process so that the corresponding target Local AC and the corresponding target AP can decide whether to update relevant files and related file signatures. In this way, unlike the prior art, the administrator no longer needs to manually trigger the relevant file synchronization operation, making the operation simpler.

[0055] The above describes the implementation process of the file synchronization method from the perspective of the Central AC. The following describes the implementation process of the file synchronization method from the perspective of the Local AC.

[0056] This application also provides a file synchronization method, which is applied to Local AC, such as... Figure 2 As shown, the method may include the following steps:

[0057] S21. Receive the first file synchronization message sent by the Central AC.

[0058] In this step, the first file synchronization message is sent by the Central AC after receiving the synchronization instruction from the administrator to instruct the Central AC to synchronize the target file corresponding to the target service to the target AP where the target service is deployed. The message carries the target file corresponding to the target service, the target file name, and the target file signature.

[0059] S22. Determine whether the target file name is stored locally; if the result is no, execute steps S23 and S24; if the result is yes, execute step S25.

[0060] S23. Store all the contents carried in the first file synchronization message.

[0061] S24. Send a first file synchronization request carrying the target file name and target file signature to the target AP connected to it.

[0062] S25. Compare the file signature corresponding to the target file name stored locally with the target file signature; if the comparison result is consistent, proceed to step S24; if the comparison result is inconsistent, proceed to step S26.

[0063] S26, updating the file corresponding to the target file name stored locally to the target file, updating the file signature corresponding to the target file name stored locally to the target file signature, and starting to execute step S24 to determine whether the target file name is stored locally by the corresponding target AP; if the determination result is no, storing all the contents carried in the first file synchronization request and obtaining and storing the target file from the corresponding target Local AC; if the determination result is yes, comparing whether the file signature corresponding to the target file name stored locally is consistent with the target file signature; if the comparison result is consistent, notifying the corresponding target Local AC that file synchronization is not needed; if the comparison result is inconsistent, updating the file corresponding to the target file name stored locally to the target file, and updating the file signature corresponding to the target file name stored locally to the target file signature.

[0064] Further, in the embodiment of the present application, the Local AC can further perform the following operations:

[0065] receiving a file acquisition request for acquiring the target file corresponding to the target file signature sent by the target AP accessing to the Local AC;

[0066] sending a file acquisition response carrying the target file to the corresponding target AP, so that the corresponding target AP updates the file corresponding to the target file signature stored locally to the target file carried in the file acquisition response after receiving the file acquisition response.

[0067] Herein, the target file signature can be carried in the acquisition request.

[0068] Further, in the embodiment of the present application, the Local AC can further perform the following operations:

[0069] when a new AP deploying the target service or a faulty target AP recovering normally is monitored, sending a second file synchronization request carrying the target file name and the latest file signature corresponding thereto to the new AP or the faulty target AP to determine whether the target file name is stored locally by the new AP or the faulty target AP; if the determination result is no, storing all the contents carried in the second file synchronization request and obtaining and storing the latest file from the corresponding target Local AC; if the determination result is yes, comparing whether the file signature corresponding to the target file name stored locally is consistent with the latest file signature; if the comparison result is consistent, notifying the corresponding target Local AC that file synchronization is not needed; if the comparison result is inconsistent, updating the file corresponding to the target file name stored locally to the latest file, and updating the file signature corresponding to the target file name stored locally to the latest file signature.

[0070] The above operation process enables automatic file synchronization for specified services on newly added APs or target APs undergoing fault recovery. Unlike existing technologies, which require administrators to manually trigger file synchronization, this process is much simpler.

[0071] The above file synchronization method will be described in detail below with reference to specific embodiments.

[0072] Assuming a hierarchical WLAN network (e.g.) Figure 3 As shown, all APs connected to Local AC1 (i.e., AP1 and APm) and all APs connected to Local AC2 (i.e., APx and APy) have a specified service (e.g., UCC service) deployed on them.

[0073] Suppose that at some point, the Central AC receives a file synchronization command from the administrator. This command contains the filename of the file corresponding to the UCC service.

[0074] The Central AC retrieves the corresponding file from its local machine based on the filename and calculates the file signature using the MD5 message digest algorithm. Then, the Central AC sends a file synchronization message containing the filename, the filename, and the target file signature to the Local AC connected to the AP that has deployed UCC service. That is, the Central AC sends the file synchronization message to Local AC 1 and Local AC 2 respectively.

[0075] Taking Local AC 1 as an example, after receiving the file synchronization message, Local AC 1 determines whether the file name is stored locally.

[0076] Assuming the judgment result is yes, then Local AC 1 compares whether the file signature corresponding to the file name stored locally is consistent with the file signature.

[0077] If the judgment result is inconsistent, then Local AC 1 will update the file corresponding to the file name in its local storage to that file name, update the file signature corresponding to the file name in its local storage to that file signature, and send a file synchronization request carrying the file name and file signature to the APs (i.e., AP1 and APm) that have deployed UCC services and are connected to it.

[0078] Taking the AP1 as an example, after receiving the file synchronization request, it is judged whether the local storage has the target file name; assuming that the judgment result is yes, at this time, the AP1 continues to compare whether the file signature corresponding to the local storage target file name is consistent with the target file signature; assuming that the comparison result is no, at this time, the AP1 updates the file corresponding to the local storage target file name to the target file, and updates the file signature corresponding to the local storage target file name to the target file signature.

[0079] From the above technical solutions, it can be seen that in the embodiments of the present application, for the APs deployed with specified services in the WLAN hierarchical networking, the Central AC no longer synchronizes the files corresponding to the specified services to the APs one by one through the corresponding Local AC, but synchronizes the files corresponding to the specified services to the corresponding Local AC, and the corresponding Local AC is responsible for completing the file synchronization operation of the specified services on the corresponding AP side, so that the processing resources of the Central AC side are greatly reduced, and compared with the existing synchronization process, the operation process is relatively simple and has good applicability.

[0080] Based on the same inventive concept, the present application also provides a file synchronization device, which is applied to a Central AC, and a structure diagram thereof is shown in Figure 4 The device specifically comprises:

Upon receiving the second file synchronization request, the new AP or the faulty target AP determines whether the target file name is stored locally. If the determination result is no, it stores all the content carried in the second file synchronization request and obtains and stores the latest file from the corresponding target Local AC. If the determination result is yes, it compares whether the file signature corresponding to the target file name stored locally is consistent with the latest file signature. If the comparison result is consistent, it notifies the corresponding target Local AC that file synchronization is not required. If the comparison result is inconsistent, it updates the file corresponding to the target file name stored locally with the latest file and updates the file signature corresponding to the target file name stored locally with the latest file signature.

Instead, it synchronizes the files corresponding to the designated services to the corresponding Local AC, which is responsible for completing the file synchronization operation of the designated services on the AP side. In this way, the processing resources on the Central AC side are greatly reduced. Moreover, compared with the existing synchronization process, the operation is simpler and has better applicability.

Optionally, the machine readable storage medium can also be at least one storage device located remotely from the aforementioned processor.
