[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] In the field of communication, the networking system gradually changes from a hardware device-based architecture to a virtualized architecture, so that virtual devices are widely used in the networking system. Taking a control-and-forward separation vBRAS as an example, the control-and-forward separation vBRAS includes a plurality of control plane devices and at least one forwarding plane device, and the plurality of control plane devices can include a master control plane device and at least one slave control plane device. In actual application, all control plane devices in the control-and-forward separation vBRAS can fail at the same time, at which time, user data on each control plane device and each forwarding plane device needs to be recovered to ensure that the services requested by each client in the networking system are normally processed. In related technologies, after any control plane device is recovered, the control plane device first establishes a communication connection with each forwarding plane device, and then sends offline control messages to all forwarding plane devices to instruct each forwarding plane device to forcibly perform offline processing on the user data table of the forwarding plane device, and then reconfigures the user data of each client to recover the user data corresponding to all clients, that is, to recover the user data table. However, in related technologies, there is a problem of low user data recovery efficiency in the process of recovering the user data. Based on this, the embodiments of the present application provide a user data recovery method, which can improve the user data recovery efficiency in the process of recovering the user data.

[0051] The user data recovery method provided by the embodiments of the present application can be applied to a networking system as shown in Figure 1 The networking system includes a control-and-forward separation vBRAS, a plurality of clients (that is, CPE devices), and a security management system. The control-and-forward separation vBRAS includes at least one control plane device and at least one forwarding plane device. In the embodiments of the present application, the security management system can be an authentication (Authentication), authorization (Authorization), and accounting (Accounting) system, that is, an AAA system. Among them, each client and each forwarding plane device are in communication connection, each forwarding plane device and the corresponding control plane device are in communication connection, and each control plane device and the security management system are in communication connection. The communication connection mode can be WiFi, Bluetooth, Ethernet, wireless connection, wired connection, etc. It should be noted that there is a connection relationship between one control plane device and at least one forwarding plane device. The above-mentioned client can be, but is not limited to, a personal computer, a notebook computer, a desktop computer, a smart phone, a smart bracelet, a smart watch, a smart home appliance, etc. The specific form of the client is not limited in the embodiments. Figure 1 The networking system includes a control-and-forward separation vBRAS, a plurality of clients (that is, CPE devices), and a security management system. The control-and-forward separation vBRAS includes at least one control plane device and at least one forwarding plane device. In the embodiments of the present application, the security management system can be an authentication (Authentication), authorization (Authorization), and accounting (Accounting) system, that is, an AAA system. Among them, each client and each forwarding plane device are in communication connection, each forwarding plane device and the corresponding control plane device are in communication connection, and each control plane device and the security management system are in communication connection. The communication connection mode can be WiFi, Bluetooth, Ethernet, wireless connection, wired connection, etc. It should be noted that there is a connection relationship between one control plane device and at least one forwarding plane device. The above-mentioned client can be, but is not limited to, a personal computer, a notebook computer, a desktop computer, a smart phone, a smart bracelet, a smart watch, a smart home appliance, etc. The specific form of the client is not limited in the embodiments.

[0052] As Figure 2 shown, a flowchart of a user data recovery method provided by an embodiment of the present application is provided, which is applied to a target control plane device in a networking system. The method can include the following steps:

[0053] S101, in a process of failure recovery of all control plane devices in a networking system, receiving a first data table sent by a forwarding plane device in the networking system, and determining a client to be offline in the networking system according to the first data table.

[0054] The process of failure recovery can be understood as a process from the failure of all control plane devices in the networking system to the recovery of at least one control plane device and the recovery of user data, or a process from the failure of all control plane devices in the networking system to the recovery of at least one control plane device and the completion of the recovery of user data.

[0055] It should be noted that any control plane device can actively establish a communication connection with each forwarding plane device after the recovery of the control plane device, or passively establish a communication connection with each forwarding plane device. Optionally, the target control plane device can be any one of at least one control plane device in the networking system that has recovered from failure. In the embodiment of the present application, the networking system includes one forwarding plane device.

[0056] Specifically, in the process of failure recovery of all control plane devices in the networking system, after the target control plane device establishes a communication connection with the forwarding plane device, the target control plane device can receive the first data table sent by the forwarding plane device in the networking system, and determine the client to be offline in the networking system according to the first data table. The first data table can be understood as a user data table, and in the embodiment of the present application, the first data table stored by each forwarding plane device in the networking system is the same.

[0057] In actual application, the first data table sent by the forwarding plane device can include user data of all clients that have been online before the failure of all control plane devices. Optionally, the user data can include multiple parameter information, such as session information, network interface, access port, backup group, IP address, service template, and user network configuration information of the corresponding client.

[0058] In an embodiment, the target control plane device can pre-train an algorithm model, and then input the first data table into the algorithm model. The algorithm model outputs an identifier of the client to be offline in the networking system, and determines the client to be offline according to the identifier of the client to be offline.

[0059] In yet another embodiment, the target control plane device can perform at least one of string extraction processing, matching processing, and analysis processing according to the first data table, and determine a client to be offline in the networking system according to a result of the processing operation.

[0060] In an embodiment, before performing the step of determining a client to be offline in the networking system according to the first data table in S101, the method can further include the following step: sending a data table acquisition request to the forwarding plane device, and acquiring the first data table sent by the forwarding plane device.

[0061] In actual application, in the process of failure recovery of all control plane devices in the networking system, after the target control plane device establishes a communication connection with the forwarding plane device, the target control plane device can send a data table acquisition request to the forwarding plane device, instructing the forwarding plane device to feed back the first data table to acquire the first data table sent by the forwarding plane device. This process can be understood as that the forwarding plane device brushes the first data table to the target control plane device.

[0062] S102, sending an offline control message to the forwarding plane device. The offline control message is used to instruct the forwarding plane device to perform offline processing on the offline client to obtain a to-be-recovered data table.

[0063] In actual application, the offline control message can be offline control signaling, or offline control instruction, which is not limited in the embodiments of the present application. In the embodiments of the present application, the offline control message carries an offline client identifier. The offline processing performed by the forwarding plane device on the offline client can be that the forwarding plane device deletes user data corresponding to the offline client from the first data table stored in the forwarding plane device, so as to force the offline client to be in an offline state, i.e., a communication interruption state, and obtain the to-be-recovered data table.

[0064] In the embodiments of the present application, the client corresponding to the missing or lost user data in the second data table can be determined as the offline client, so as to force the offline client to be offline, and the client corresponding to the user data still existing in the second data table is not forced to be offline. In this way, large-scale client offline and re-online can be avoided, so as to shorten the load of offline processing and the time required for offline processing.

[0065] S103, configuring new user data for the offline client, and performing user data recovery on the to-be-recovered data table and the second data table according to the new user data. The number of user data included in the second data table is less than the number of user data included in the first data table.

[0066] Specifically, the target control plane device can reconfigure corresponding parameter information of the offline client according to each parameter in the first data table, obtain new user data of the offline client, and perform user data recovery on the to-be-recovered data table and the second data table according to the new user data.

[0067] In an implementation manner, the target control plane device can send the new user data to a third-party device, and instruct the third-party device to perform user data recovery on the to-be-recovered data table and the second data table.

[0068] In another implementation manner, the target control plane device can call a user data recovery tool, and input the new user data into the user data recovery tool to perform user data recovery on the to-be-recovered data table and the second data table.

[0069] In the embodiments of the present application, the number of user data contained in the second data table is less than the number of user data contained in the first data table. Meanwhile, the number of user data contained in the to-be-recovered data table is equal to the number of user data contained in the second data table.

[0070] The technical solution in the embodiments of the present application is applied to a target control plane device in a networking system. In the process of failure recovery of all control plane devices in the networking system, the target control plane device receives a first data table sent by a forwarding plane device in the networking system, determines offline clients that need to be offline in the networking system according to the first data table, sends an offline control message to the forwarding plane device to instruct the forwarding plane device to perform offline processing on the offline clients to obtain a to-be-recovered data table, configures new user data for the offline clients, and performs user data recovery on the to-be-recovered data table and a second data table according to the new user data, wherein the number of user data contained in the second data table is less than the number of user data contained in the first data table. The above method does not need to perform forced offline processing on all clients in the networking system. Instead, offline clients that need to be offline in the networking system are determined first, and then forced offline processing is performed on the offline clients, i.e., part of the clients in the networking system, to achieve user data recovery of all clients in the networking system. This can shorten the time required for forced offline processing, speed up the user data recovery speed, and improve the user data recovery efficiency. On this basis, it can avoid a large number of clients being offline and online at the same time, shorten the interruption time of the clients, speed up the business recovery processing speed, and improve the user experience. Meanwhile, the above method does not need to perform forced offline processing on all clients in the networking system. This can not only reduce the offline processing pressure of the forwarding plane device, but also reduce the complexity of the recovery clients being online again, and improve the widespread applicability of user data recovery.

[0071] The process of determining offline clients that need to be offline in the networking system according to the first data table is described below. In an embodiment, as shown in FIG. 2, the target control plane device can determine offline clients that need to be offline in the networking system according to the first data table.Figure 3 As shown in the above S102, the steps can be implemented in the following manner:

[0072] S112, matching each user data in the first data table with each user data in the second data table.

[0073] In actual application, the target control plane device can use a matching algorithm to match each user data in the first data table with each user data in the second data table, so as to complete the reconciliation processing of the first data table and the second data table.

[0074] The matching algorithm can be a string matching algorithm, an exact matching algorithm, a fuzzy matching algorithm, a numerical value matching algorithm, a clustering algorithm, etc., which is not limited by the embodiments of the present application.

[0075] In addition, the target control plane device can also pre-train a matching model, and then input the first data table and the second data table into the matching model. The matching model outputs the matching result after matching each user data in the first data table with each user data in the second data table. Optionally, the matching model can be implemented by at least one of a convolutional neural network model, a fully connected neural network model, a long short-term memory neural network model, a recurrent neural network model, and a residual neural network model.

[0076] S122, determining the client corresponding to the user data that fails to match as an offline client in the networking system.

[0077] Specifically, the target control plane device can determine the client corresponding to the user data that fails to match in the matching result as an offline client in the networking system. It should be noted that the user data that fails to match can be understood as the user data missing or lost from the second data table due to the failure of the target control plane device.

[0078] The technical solution in the embodiments of the present application matches each user data in the first data table with each user data in the second data table, and determines the client corresponding to the user data that fails to match as an offline client in the networking system. The above method can quickly determine the offline client in the networking system by using the user data tables stored by the control plane device and the forwarding plane device in the networking system, so as to provide reference information for shortening the time required for subsequent offline operation.

[0079] In actual application, after all the control plane devices fail, some instabilities or potential security vulnerabilities may occur in the network environment. Therefore, after the target control plane device recovers, the target control plane device needs to request the security management system to perform legitimacy authentication on the user of the client that is online again. The process of legitimacy authentication on the user is described below. In an embodiment, before performing the steps in S103 described above, the target control plane device can perform the following steps, as shown in FIG. 1. Figure 4 The method described above can further include the following steps:

[0080] S104. In the case where the offline processing is completed, in response to the access request sent by the offline client and received by the forwarding plane device, the target control plane device sends a legitimacy access authentication request to the security management system in the networking system, instructing the security management system to perform legitimacy authentication on the user corresponding to the access request.

[0081] Specifically, in the case where the offline processing on the offline client is completed by the forwarding plane device, the forwarding plane device can receive the access request sent by the user through the offline client at any time, that is, the call request. The access request is a request generated by the user dialing through the offline client by using the Point-to-Point Protocol Over Ethernet (PPPoE) or the IP over Ethernet (IPoE). Correspondingly, the target control plane device can receive and respond to the access request sent by the offline client and received by the forwarding plane device, generate a legitimacy access authentication request according to the access request, and send the legitimacy access authentication request to the security management system in the networking system, instructing the security management system to perform legitimacy authentication on the user corresponding to the access request, to verify the legitimacy of the user.

[0082] The access request and the legitimacy access authentication request can both carry, but are not limited to, user information, which can include username, password, authentication and charging information. Specifically, the security management system can compare the user information carried in the legitimacy access authentication request with the standard user information corresponding to the user in the user information library. If the user information is consistent with the corresponding standard user information, it is determined that the legitimacy authentication of the user is passed, otherwise, the legitimacy authentication of the user is not passed.

[0083] In addition, the security management system can use a matching algorithm to perform matching processing on the user information carried in the legitimacy access authentication request and the standard user information corresponding to the user in the user information library, and determine whether the user information exists in the user information library according to the matching result. If the user information exists, it is determined that the legitimacy authentication of the user is passed, otherwise, the legitimacy authentication of the user is not passed.

[0084] S105, in the case of passing the legality authentication, performing a step of configuring the offline client with new user data.

[0085] In the embodiments of the present application, in the case of passing the legality authentication, the target control plane device can continue to perform the step of configuring the offline client with new user data.

[0086] The technical solutions in the embodiments of the present application, in the case of completing the offline processing, in response to the access request sent by the offline client and received by the forwarding plane device, sending a legality access authentication request to the security management system in the networking system, instructing the security management system to perform legality authentication on the corresponding user of the access request, in the case of passing the legality authentication, performing the step of configuring the offline client with new user data; the above method can request the security management system to perform legality authentication on the user using the client that is online again, which can guarantee the security of the network, so as to avoid the problem that a large amount of resources in the network are occupied by illegal users, causing legitimate users to be unable to normally use services, and improve the quality of network services.

[0087] The process of recovering user data from the to-be-recovered data table and the second data table according to the new user data is described below. In an embodiment, the step of recovering user data from the to-be-recovered data table and the second data table according to the new user data in S103 can include: adding the new user data to the second data table, and sending the new user data to the forwarding plane device, instructing the forwarding plane device to add the new user data to the to-be-recovered data table to complete user data recovery.

[0088] Specifically, the target control plane device can add each parameter information in the new user data to each parameter in the second data table to complete user data recovery of the second data table.

[0089] Meanwhile, the target control plane device can send the new user data to the forwarding plane device, instructing the forwarding plane device to add each parameter information in the new user data to each parameter in the to-be-recovered data table to complete user data recovery of the to-be-recovered data table.

[0090] In addition, the target control plane device can send the new user data to each other control plane device in the networking system, instructing each other control plane device to add the new user data to the to-be-recovered data table of each other control plane device to synchronize user data recovery of the to-be-recovered data table, regenerate the first data table, and realize the normal state, i.e., the control capability, of the multiple control plane devices in the networking system.

[0091] The technical solution in the embodiments of the present application adds the newly created user data to the second data table, and sends the newly created user data to the forwarding plane device, instructing the forwarding plane device to add the newly created user data to the data table to be recovered, so as to complete the user data recovery. The above method does not require a complex processing process, and only needs to add the user data of the offline client to the user data table, so that the user data recovery can be completed, the processing process is relatively simple, thereby reducing the complexity of the user data recovery, greatly accelerating the speed of the user data recovery, and improving the efficiency of the user data recovery. Meanwhile, the above method does not require manual participation, thereby reducing the manual participation error, and greatly improving the accuracy of the user data recovery.

[0092] In an embodiment, the embodiments of the present application also provide a user data recovery method applied to a target control plane device in a networking system, which comprises the following processes:

[0093] S11. In the process of failure recovery of all control plane devices in the networking system, a data table acquisition request is sent to the forwarding plane device in the networking system, and a first data table sent by the forwarding plane device is received.

[0094] S12. Each user data in the first data table is matched with each user data in a second data table.

[0095] S13. A client corresponding to the user data that fails to match is determined as an offline client in the networking system.

[0096] S14. An offline control message is sent to the forwarding plane device, instructing the forwarding plane device to perform offline processing on the offline client to obtain a data table to be recovered.

[0097] S15. In the case where the offline processing is completed, in response to an access request sent by the offline client and received by the forwarding plane device, a legality access authentication request is sent to a security management system in the networking system, instructing the security management system to perform legality authentication on a user corresponding to the access request.

[0098] S16. In the case where the legality authentication is passed, newly created user data is configured for the offline client.

[0099] S17. The newly created user data is added to the second data table, and the newly created user data is sent to the forwarding plane device, instructing the forwarding plane device to add the newly created user data to the data table to be recovered, so as to complete the user data recovery. The number of user data contained in the second data table is less than the number of user data contained in the first data table.

[0100] The execution processes of S11 to S17 above can refer to the description of the above embodiments for details, and have similar implementation principles and technical effects, which will not be described here again.

[0101] As Figure 5 shown, a flowchart of a user data recovery method provided by an embodiment of the present application is provided, which is applied to a forwarding plane device in a networking system, and the method can include the following steps:

[0102] S201, in response to an offline control message sent by a target control plane device in a networking system, performing offline processing on an offline client in the networking system to obtain a to-be-recovered data table. The offline client is determined by the target control plane device according to a first data table sent by a forwarding plane device in a process of failure recovery of all control plane devices in the networking system.

[0103] The process of failure recovery can be understood as a process from when all control plane devices in the networking system fail until at least one control plane device is recovered from failure and before user data is recovered, or a process from when all control plane devices in the networking system fail until at least one control plane device is recovered from failure and user data recovery is completed.

[0104] It should be noted that any control plane device can actively establish a communication connection with each forwarding plane device after the control plane device is recovered from failure, or can establish a communication connection with each forwarding plane device based on a passive triggering mode. Optionally, the target control plane device can be any one of at least one control plane device recovered from failure in the networking system. In the embodiment of the present application, the networking system includes one forwarding plane device.

[0105] Specifically, in the process of failure recovery of all control plane devices in the networking system, after the target control plane device establishes a communication connection with the forwarding plane device, the target control plane device can first receive a first data table sent by the forwarding plane device in the networking system, and determine an offline client that needs to be offline in the networking system according to the first data table, then generate an offline control message based on the offline client, and send the offline control message to the forwarding plane device. In the embodiment of the present application, the offline control message carries an offline client identifier; and the offline control message carries the offline client identifier.

[0106] Correspondingly, the forwarding plane device can receive and respond to the offline control message sent by the target control plane device in the networking system, and perform offline processing on the offline client in the networking system to obtain the to-be-recovered data table.

[0107] Specifically, the forwarding plane device can delete user data corresponding to the offline client from the first data table stored in the forwarding plane device to forcibly make the offline client in an offline state, i.e., a communication interruption state, to obtain the to-be-recovered data table.

[0108] In actual application, the offline control message can be offline control signaling or offline control instruction, which is not limited by the embodiments of the present application. The offline processing manner of the forwarding plane device on the offline client can be that the forwarding plane device deletes the user data corresponding to the offline client from the first data table stored by itself, so as to force the offline client to be in an offline state, i.e., a communication interruption state, and obtain the to-be-recovered data table.

[0109] S202, sending an access request sent by the offline client to the target control plane device, instructing the target control plane device to configure new user data for the offline client, and performing user data recovery on the to-be-recovered data table and the second data table according to the new user data. The number of user data contained in the second data table is less than the number of user data contained in the first data table.

[0110] Specifically, the forwarding plane device receives an access request sent by the offline client, i.e., a call request. Correspondingly, the forwarding plane device can forward the access request sent by the offline client to the target control plane device, instructing the target control plane device to configure new user data for the offline client, and performing user data recovery on the to-be-recovered data table and the second data table according to the new user data.

[0111] Specifically, the target control plane device can reconfigure each corresponding parameter information of the offline client according to each parameter in the first data table, obtain new user data of the offline client, and perform user data recovery on the to-be-recovered data table and the second data table according to the new user data.

[0112] In an implementation manner, the target control plane device can send the new user data to a third-party device, instructing the third-party device to perform user data recovery on the to-be-recovered data table and the second data table.

[0113] In another implementation manner, the target control plane device can call a user data recovery tool, and input the new user data into the user data recovery tool to perform user data recovery on the to-be-recovered data table and the second data table.

[0114] In the embodiments of the present application, the number of user data contained in the second data table is less than the number of user data contained in the first data table. Meanwhile, the number of user data contained in the to-be-recovered data table is equal to the number of user data contained in the second data table.

[0115] The technical solution in the embodiments of the present application, in response to the offline control message sent by the target control plane device in the networking system, performs offline processing on the offline client in the networking system to obtain the to-be-recovered data table, and sends the access request sent by the offline client to the target control plane device, instructs the target control plane device to configure new user data for the offline client, and performs user data recovery on the to-be-recovered data table and the second data table according to the new user data, wherein the offline client is determined by the target control plane device according to the first data table sent by the forwarding plane device in the process of failure recovery of all control plane devices in the networking system, and the number of user data contained in the second data table is less than the number of user data contained in the first data table; the above method does not need to force all clients in the networking system to be offline, and can first determine the offline clients that need to be offline in the networking system, and then force the offline clients in the networking system, that is, part of the clients to be offline, to achieve user data recovery of all clients in the networking system, which can shorten the time required for forced offline processing, speed up the user data recovery speed, and improve the user data recovery efficiency, on the basis of which, the interruption time of the client can be shortened, the business recovery processing speed can be accelerated, and the user experience can be improved; at the same time, the above method does not need to force all clients in the networking system to be offline, which not only can reduce the offline processing pressure of the forwarding plane device, but also can reduce the complexity of the recovery client re-online, and improve the widespread applicability of user data recovery.

[0116] The process of performing the step of sending the access request sent by the offline client to the target control plane device is described below. In an embodiment, the above method can further include the following steps: in the case where the offline processing is completed, in response to the access request sent by the offline client, performing the step of sending the access request sent by the offline client to the target control plane device.

[0117] Specifically, in the case where the offline processing of the offline client by the forwarding plane device is completed, the forwarding plane device can receive the access request sent by the user through the offline client at any time, and in response to the access request sent by the offline client, forwards the access request sent by the offline client to the target control plane device.

[0118] In one embodiment, after performing the steps in S202, the above method can further include: receiving the new user data sent by the target control plane device, and adding the new user data to the to-be-recovered data table to complete the user data recovery in the to-be-recovered data table.

[0119] The target control plane device can configure new user data for the offline client after receiving the access request of the offline client, and send the new user data to the forwarding plane device.

[0120] Correspondingly, the forwarding plane device can receive the new user data sent by the target control plane device, add each parameter information in the new user data to each parameter in the to-be-recovered data table, so as to complete the user data recovery of the to-be-recovered data table, that is, regenerate the first data table.

[0121] The technical solution in the embodiments of the present application, in the case that the offline processing is completed, in response to the access request sent by the offline client, performs the step of sending the access request sent by the offline client to the target control plane device; in the above method, after the offline client is forced to be offline by the forwarding plane device, the offline client can be allowed to be online again, that is, the access request sent by the offline client is received and forwarded, so as to recover the user data, and the processing process is relatively simple and does not need complex algorithms to participate, thereby the complexity of the online again of the offline client can be reduced and the speed of the online again of the offline client can be accelerated.
