With the development of informatization technology, more and more intelligent terminals need to access to a network to meet scene requirements such as business processing, office automation, intelligent monitoring and the like. Thus, at the network edge side, network devices providing network access, routing switching functions are deployed in large numbers and demand is still continuously growing.

Aiming at the problems in the prior art, the application provides a method and a device for determining solution information of a network equipment configuration problem, and a search operation is executed in response to receiving the configuration problem corresponding to the fault network equipment, wherein the search operation comprises searching whether solution information corresponding to the configuration problem is stored in an expert database corresponding to the search operation; if not, the configuration problem is sent to at least one other repairing device, the other repairing device and the currently searched repairing device form an association relation, and the other repairing device executes the searching operation until the currently searched repairing device searches out corresponding solution information from an expert database corresponding to the other repairing device. The invention reduces the construction cost of the communication line and the central cloud service based on the distributed characteristics, realizes high automation, does not need manual intervention, and greatly shortens the time window of network recovery.
The method and the device for determining the solution information of the network equipment configuration problem provided by the invention are described in detail below with reference to the accompanying drawings.
In a specific embodiment, the present application provides a method for determining solution information of a network device configuration problem, where each network device is correspondingly coupled to a repair device in a distributed network, each repair device stores a unique corresponding expert database, and each expert database stores solution information of at least one configuration problem; the solution information determining method, as shown in fig. 1, is executed by a repairing device corresponding to the faulty network device, and includes:
S1, responding to received configuration problems corresponding to fault network equipment, and executing search operation, wherein the search operation comprises searching whether solution information corresponding to the configuration problems is stored in an expert database corresponding to the search operation;
and S2, if not, sending the configuration problem to at least one other repairing device, wherein the other repairing device and the currently searched repairing device form an association relation, and the other repairing device executes the searching operation until the currently searched repairing device searches out corresponding solution information from an expert database corresponding to the other repairing device.
In particular embodiments, the network devices include, but are not limited to, common network devices located at the edge of the network, such as two-layer switches, three-layer switches, routers, and wireless Access Points (APs) that provide network access and routing switching functions. Each network device is correspondingly coupled with a repairing device in the distributed network, each repairing device stores a unique corresponding expert database, and each expert database stores solution information of at least one configuration problem. The configuration problem refers to a problem that network equipment cannot be communicated due to non-configuration, configuration error or configuration loss, and the initial state of the network equipment just leaves the factory or is restored after the network equipment leaves the factory is not configured.
In a specific embodiment, for a repair device to which a failed network device is correspondingly coupled, a configuration problem of the failed network device needs to be determined according to device information corresponding to the failed network device, where the repair device needs to collect device information of the failed network device, where the device information is various information used for analyzing the configuration problem, such as configuration information, running state information, and the like, for example, ip address information, default gateway, domain name and domain name server, port attribute, mac address table, and the like. The repair device, which is correspondingly coupled to the network device with the fault, determines the configuration problem of the current fault according to the collected device information, for example, the collected ip address information is 0.0.0.0, and then the configuration problem can be determined that the network device is the device just leaving the factory, and belongs to the non-configuration problem. In a specific embodiment, after determining a configuration problem corresponding to a faulty network device, in response to the configuration problem, a search operation is performed on a repair device coupled to the faulty network device, and whether a solution corresponding to the configuration problem is stored is searched from an expert database corresponding to the repair device. Solutions stored in, for example, expert libraries are as follows:
The problem is that the ip address of the switch is not configured; the solution is to query the ip address information of the switch by running cmd telnet, and write the queried ip address information into the corresponding network equipment;
the problem is that the mac address table of the switch is not configured; the solution is to turn on the mac address collector, add a whitelist group in the "group configuration" and configure in all mac addresses to be released.
It can be seen from the above that the solution corresponding to the ip address is not configured can be searched out from the stored solutions, so that the searched solution is executed, the faulty network device is repaired, the first solution is formatted into a correction command, and then the correction command is written into the network device to verify whether the first solution is valid.
In a specific embodiment, if no corresponding solution is searched in the expert database of the repair device to which the network device that has failed is correspondingly coupled, the configuration problem is sent to at least one other repair device, where the other repair device and the currently searched repair device form an association relationship. As shown in fig. 2, if the network device a fails and no corresponding solution is searched for in the repair device A0 coupled to the network device a, the repair device A0 transmits the configuration problem to the repair device B0 and the repair device C0 associated therewith, so that the repair devices B0 and C0 search for the solution corresponding to the configuration problem in their own knowledge base. If neither of the repair devices B0 and C0 searches for a corresponding solution, the repair device B0 transmits the configuration problem to the repair devices B1 and B2 associated therewith so that the repair devices B1 and B2 search for solutions from their own expert libraries, respectively, and the repair device C0 transmits the configuration problem to the repair devices C1 and D0 associated therewith so that the C1 and D0 search for their own expert libraries. On the other hand, in order that only the repair device associated with the repair device transmitting the configuration problem can receive the configuration problem, the configuration problem to be solved is encrypted in an asymmetric encryption manner. In the repairing device with any association, the currently searched repairing device stores a preset public key, encrypts the configuration problem by adopting the preset public key, and then broadcasts the encrypted configuration problem to the distributed network; and storing corresponding preset private keys in other repairing devices associated with the repairing device, decrypting the encrypted configuration problem by using the preset private keys, and finally obtaining a configuration problem plaintext. For example, as shown in the figure, assuming that the currently searched repair device is B0 and no solution is searched, B0 encrypts the configuration problem to be solved by using a preset public key to obtain a configuration problem ciphertext, the configuration problem ciphertext is broadcast to a distributed network, after the repair devices A0, C0, B1, B2, C1 and D0 in the distributed network receive the configuration problem ciphertext, the repair devices decrypt by using preset private keys stored in the repair devices A0, C0, B1, B2 and D0, and since the preset public key and the preset private key are paired, the ciphertext can only be decrypted by using a preset private key corresponding to the encryption of B0, that is, only the preset private key stored in the repair devices A0, C0, B1 and B2 associated with B0 can decrypt the configuration problem ciphertext, and the preset private keys stored in C1 and D0 cannot decrypt the configuration problem ciphertext sent by B0. And so on, covering all repair devices in the entire distributed network until a solution is searched.
In a specific embodiment, if all repairing apparatuses do not search for solution information of a configuration problem corresponding to the faulty network device, the configuration problem is input into a preset machine learning model, and corresponding solution information is generated, where the machine learning model is built based on the historical configuration problem and the corresponding solution information. For example, a convolutional neural network model is employed to learn a convolutional neural network model of a configuration problem and corresponding solution. And taking the history configuration problem as an input parameter of the model, taking a corresponding solution as a target output parameter of the model, and training the convolutional neural network model according to the target output parameter to obtain the preset machine learning model.
In a specific embodiment, after a solution corresponding to a configuration problem is learned by a repair device coupled to a faulty network device using a machine learning model, the solution information is transmitted to other repair devices associated with the fault network device, so that the other repair devices receive the solution information and store the solution information in their own knowledge base. The self-learning result is backed up in multiple times, and after a certain device is disconnected, the self-learning result can be obtained by searching from expert libraries of other related repairing devices, so that the robustness of the whole distributed self-organizing network is ensured.
In a specific embodiment, after the solution information corresponding to the configuration problem is determined, the configuration problem of the faulty network device is repaired according to the solution information, the solution is formatted into a correction command, and then the correction command is written into the network device to verify whether the solution one is valid. In a specific embodiment, before writing the correction command corresponding to the solution into the network device with the fault, the configuration information generated in the process, the determined configuration problem and the solution thereof, and the correction command are written into the log, so as to ensure that the configuration problem can be quickly rolled back according to the log when the configuration problem cannot be solved.
The invention will be further described with reference to a specific implementation scenario.
Scene one: taking the configuration problem of the router as an example
According to the method provided by the invention, the configuration problem of the router comprises the following steps, as shown in fig. 3:
and S101, connecting the router with one repair device in a wired mode or a wireless mode, and then sending a greeting packet by the repair device to search other repair devices associated with the greeting packet. When receiving the return packet of the greeting packet, confirming the association relation and sending a request packet to request the establishment of connection. And the other repairing devices associated with the request packet enter a connection mode after receiving the request packet, and reply the repairing device sending the request packet. The repairing device sending the request packet also enters a connection mode after receiving the reply, establishes a connection relationship with other associated repairing devices, and thus joins the distributed network. Each repair device in the distributed network periodically collects the equipment information of the router, extracts key information by analyzing the equipment information, searches an expert database according to the key information, and determines a corresponding configuration problem. If the matched configuration problems are more than one, the problem queues are added in sequence. For example, there is only one configuration problem with the router, specifically "routing table lacks a route to the application server". And continuing searching the expert database according to the determined configuration problem to acquire a corresponding solution. And if the length of the problem queue exceeds 1, sequentially dequeuing, and sequentially searching out corresponding solutions to form a solution queue. For example, the configuration problem of the router is "routing table lacks a route to the application server", and the solution is "static route added to the application server" obtained by searching the expert database. The solution is formatted into a string command or set of commands, called a correction command, and the correction command is written to the router. Before confirming writing, writing configuration information generated in the diagnosis process, associated configuration problems, solutions of the configuration problems and correction commands into a log. For example, the solution is formatted as a command "ip route des_ IP MASK INTERFACE". If the correction command is valid, the configuration problem of the router is solved, and the operation flow is ended. If the configuration issuing module verifies that the correction command is invalid, the expert database of the device does not contain the problem and the corresponding solution.
And S102, searching corresponding solutions from expert libraries of all repair devices in the whole distributed network. And packaging and encrypting the configuration problem information to generate a first data packet, and sending the first data packet to other repairing devices associated with the first data packet. And if the result is found, directly replying to the device for sending the first data packet, otherwise, forwarding the first data packet to other repair devices associated with the device, and executing search operation by the other repair devices associated with the device. If the problem of the router found after searching is that the access control list blocks the reply of the application server, the corresponding solution is that the access control list releases the access of the application server. After searching the result, the other repairing device devices associated with the repairing device can package the result and reply the result to the device for sending the first data packet. The device performs repair operations, such as formatting the solution as a command "permit IP host DES _ip MASK any". If the re-verification correction command is invalid, the expert database representing the whole network does not contain the problem and the corresponding solution.
And S103, selecting a proper model from a model library by a repairing device coupled with the network device with the fault, and generating a new solution based on the machine learning model. If the configuration issuing module verifies that the new solution is valid, the configuration problem and the new solution are associated and stored in an expert database. While the associated configuration problem and new solution are packaged into a second data packet and then sent to other repair devices directly associated therewith. The other repairing device devices associated with the repairing device receive the second data packet, analyze out the configuration problem and the new solution, store the configuration problem and the new solution only in the expert database of the repairing device, and not send the configuration problem and the new solution to the outside.
As can be seen from the above description, the solution information determining method for a configuration problem of a network device according to the present invention performs a search operation in response to receiving a configuration problem corresponding to a faulty network device, where the search operation includes searching from an expert database corresponding to the search operation whether solution information corresponding to the configuration problem is stored; if not, the configuration problem is sent to at least one other repairing device, the other repairing device and the currently searched repairing device form an association relation, and the other repairing device executes the searching operation until the currently searched repairing device searches out corresponding solution information from an expert database corresponding to the other repairing device. The invention reduces the construction cost of the communication line and the central cloud service based on the distributed characteristics, realizes high automation, does not need manual intervention, and greatly shortens the time window of network recovery.
From a software aspect, the present application provides an embodiment of a solution information determining apparatus for executing a network device configuration problem of all or part of contents in a solution information determining method for a network device configuration problem, referring to fig. 4, where the solution information determining apparatus for a network device configuration problem specifically includes the following contents:

the solution searching module 1 is used for responding to the received configuration problem corresponding to the fault network equipment and executing searching operation, wherein the searching operation comprises searching whether solution information corresponding to the configuration problem is stored in an expert database corresponding to the searching operation;
and the configuration problem sending module 2 is used for sending the configuration problem to at least one other repairing device, wherein the other repairing device and the currently searched repairing device form an association relation, and the other repairing device executes the searching operation until the currently searched repairing device searches out corresponding solution information from an expert database corresponding to the other repairing device.
In particular embodiments, the network devices include, but are not limited to, common network devices located at the edge of the network, such as two-layer switches, three-layer switches, routers, and wireless Access Points (APs) that provide network access and routing switching functions. Each network device is correspondingly coupled with a repairing device in the distributed network, each repairing device stores a unique corresponding expert database, and each expert database stores solution information of at least one configuration problem. The configuration problem refers to a problem that network equipment cannot be communicated due to non-configuration, configuration error or configuration loss, and the initial state of the network equipment just leaves the factory or is restored after the network equipment leaves the factory is not configured.
In a specific embodiment, for the repair device to which the failed network device is correspondingly coupled, the configuration problem of the failed network device needs to be determined according to the device information corresponding to the failed network device, so a configuration problem determining module needs to be further loaded, and the configuration problem determining module is further configured to collect the device information of the failed network device and determine the corresponding configuration problem, where the device information is various information used for analyzing the configuration problem, such as ip address information, default gateway, domain name and domain name server, port attribute, mac address table, and the like. The repair device, which is correspondingly coupled to the network device with the fault, determines the configuration problem of the current fault according to the collected device information, for example, the collected ip address information is 0.0.0.0, and then the configuration problem can be determined that the network device is the device just leaving the factory, and belongs to the non-configuration problem. In a specific embodiment, after determining a configuration problem corresponding to a faulty network device, invoking a solution searching module 1, executing a searching operation for a repair device coupled to the faulty network device corresponding to the configuration problem, and searching whether a solution corresponding to the configuration problem is stored in an expert database corresponding to the repair device. Solutions stored in, for example, expert libraries are as follows:
The problem is that the ip address of the switch is not configured; the solution is to query the ip address information of the switch by running cmd telnet, and write the queried ip address information into the corresponding network equipment;
the problem is that the mac address table of the switch is not configured; the solution is to turn on the mac address collector, add a whitelist group in the "group configuration" and configure in all mac addresses to be released.
From the above, the solutions corresponding to the ip address unconfigured solutions can be searched out from the stored solutions, so that the searched solutions are executed to repair the faulty network device. The repair device coupled to the failed network device also needs to have a configuration problem repair module to perform formatting of the solution one into a correction command and then writing the correction command to the network device to verify whether the solution one is valid.
In a specific embodiment, if no corresponding solution is searched in the expert database of the repair device to which the network device that has failed is correspondingly coupled, the configuration problem sending module 2 is invoked to send the configuration problem to at least one other repair device, where the other repair device and the currently searched repair device form an association relationship. As shown in fig. 2, if the network device a fails, and after the repair device A0 coupled to the network device a invokes the configuration problem determining module to determine the corresponding configuration problem, the solution searching module 1 is invoked, and as a result, no corresponding solution is searched, the repair device A0 sends the configuration problem to the repair device B0 and the repair device C0 associated with the configuration problem through the configuration problem sending module 2, so that the repair devices B0 and C0 respectively invoke the solution searching modules of the repair device a and the repair device C0 to execute searching the solution corresponding to the configuration problem in the knowledge base of the repair device a and the repair device C0. If neither of the repair devices B0 and C0 searches for a corresponding solution, the repair device B0 invokes its own configuration problem sending module to send the configuration problem to the repair devices B1 and B2 associated therewith, so that the repair devices B1 and B2 respectively invoke their own solution searching modules to search for a solution from their own expert libraries, the repair device C0 invokes its own configuration problem sending module to send the configuration problem to the repair devices C1 and D0 associated therewith, so that the C1 and D0 invoke their own solution searching modules to search their own expert libraries. On the other hand, in order that only the repair device associated with the repair device transmitting the configuration problem can receive the configuration problem, the configuration problem to be solved is encrypted in an asymmetric encryption manner. In any repairing device that forms an association relationship, the currently searched repairing device stores a preset public key, so the configuration problem sending module 2 further includes: a configuration problem encryption unit which encrypts the configuration problem by adopting the preset public key; and the configuration problem broadcasting unit broadcasts the encrypted configuration problem to the distributed network. And storing corresponding preset private keys in other repairing devices associated with the repairing device, decrypting the encrypted configuration problem by using the preset private keys, and finally obtaining a configuration problem plaintext. For example, as shown in fig. 2, assuming that the currently searched repair device is B0 and no solution is searched, B0 encrypts the configuration problem to be solved by using a preset public key to obtain a configuration problem ciphertext, the configuration problem ciphertext is broadcast to a distributed network, after the repair devices A0, C0, B1, B2, C1 and D0 in the distributed network receive the configuration problem ciphertext, the repair devices are decrypted by using preset private keys stored in the repair devices, and since the preset public key and the preset private keys are paired, the ciphertext can be decrypted only by using the preset private key corresponding to the encryption of B0, that is, only the preset private key stored in the repair devices A0, C0, B1 and B2 associated with B0 can decrypt the configuration problem ciphertext, and the preset private keys stored in C1 and D0 cannot decrypt the configuration problem ciphertext sent by B0. And so on, covering all repair devices in the entire distributed network until a solution is searched.
In a specific embodiment, if all repairing apparatuses do not search for solution information of a configuration problem corresponding to the faulty network device, a solution learning module is required to be called, the configuration problem is input into a preset machine learning model, and corresponding solution information is generated, wherein the machine learning model is established based on the historical configuration problem and the corresponding solution information. For example, a convolutional neural network model is employed to learn a convolutional neural network model of a configuration problem and corresponding solution. And taking the history configuration problem as an input parameter of the model, taking a corresponding solution as a target output parameter of the model, and training the convolutional neural network model according to the target output parameter to obtain the preset machine learning model.
In a specific embodiment, after a repairing device coupled to a fault network device learns a solution corresponding to a configuration problem by using a machine learning model, a solution transmission unit is called to transmit the solution information to other repairing devices associated with the solution, so that the other repairing devices receive the solution information and store the solution information in their own knowledge base. The self-learning result is backed up in multiple times, and after a certain device is disconnected, the self-learning result can be obtained by searching from expert libraries of other related repairing devices, so that the robustness of the whole distributed self-organizing network is ensured.
In a specific embodiment, after determining the solution information corresponding to the configuration problem, a repairing device coupled to the faulty network device invokes a configuration problem repairing module, repairs the configuration problem of the faulty network device according to the solution information, formats the solution into a correction command, and then writes the correction command into the network device to verify whether the solution is valid. In a specific embodiment, before writing the correction command corresponding to the solution into the network device with the fault, the configuration information generated in the process, the determined configuration problem and the solution thereof, and the correction command are written into the log, so as to ensure that the configuration problem can be quickly rolled back according to the log when the configuration problem cannot be solved.
