The office locations of a large-scale company or a large-scale unit are often in a plurality of different cities, and the office locations are communicated and communicated through network equipment, namely network points, so that the problems of more network points and difficult management occur, and an intelligent network point management system can well solve the problems, but the normal operation of the intelligent network point management system is very important.
The inventors have intensively studied and found that: the use of the intelligent network management system in the current network environment is the condition of the control equipment of a single intelligent network management system, the safety is low, and when a problem occurs, the network can not be continuously and instantly managed in a unified way. An alternative control device of the intelligent network management system can be added to replace a control device with an unexpected problem at any time, namely a master control device. The network management system can ensure normal management and monitoring of network equipment, and the alternative control equipment needs to replace the master control equipment to work, so that the alternative control equipment has the same configuration as the master control equipment, and the normal operation of the intelligent network management system is ensured.
The embodiment of the disclosure provides an information synchronization method, which keeps the information of an alternative control device and the information of a main control device synchronized, so that the alternative control device can replace a failed main control device to continue working.
As shown in fig. 1, fig. 1 is a flowchart illustrating a method for information synchronization, which may be used in an alternative control device, according to an embodiment of the present disclosure, and includes the following steps:
step S11, receiving target information sent by a master control device, where the target information is associated information when the master control device manages a website device.
Hereinafter, the main control device is simply called a host, and the alternative control device is simply called a standby.
In this step, when the host manages the website device, for example, adding a new website and configuring website information, configuring an alarm action of a certain website or multiple websites, monitoring the website, analyzing website traffic logs, and the like, in the process, the configuration state of the host changes, or the master control device generates new file information, or the host obtains the state information of the website device, and the like, which are the relevant information. The association information may include: operation information of the host, state information of the network points, configuration information, file information and other various information related to the main control equipment.
Before this step, the primary-backup relationship between the host and the backup needs to be established. The host machine and the standby machine are both devices provided with intelligent network management systems. The address of the standby machine can be configured on the host machine, when the standby machine is started, the host machine can send the initial priority to the address of the standby machine through the webservice interface, and the standby machine can store the initial priority into the data table and return the host machine success information after receiving the initial priority of the host machine, so that the main-standby relationship is established. The initial priority may be an IP address, for example, the IP address of the host is initially set to 1.1.1.1, the IP address of the standby device is 1.1.1.2, and the standby device with the IP address of 1.1.1.2 can confirm that the other party is the host when receiving the information with the IP address of 1.1.1.1; or may be a number, the largest being the host. Or a server, such as an Nginx server, may be deployed, the primary-secondary relationship is configured in advance according to the IP addresses of the host and the secondary machine, and when the host fails, the primary-secondary relationship is re-determined.
Step S12, when the target information includes operation information when the master control device manages the mesh point device, determining and storing data configured when the master control device manages the mesh point device based on the target information.
The operation information may be various operation data of the host, such as a class, a method, and a parameter corresponding to a certain operation, or operation data in a database corresponding to a management operation of the host, or operation data in a log record corresponding to the management operation of the host. After receiving the operation data of the host, the standby machine can restore the operation corresponding to the operation data and execute the same action as the host to achieve the configuration synchronization with the host. It is also possible to not perform the same operation as the host, but directly use the operational data in the database to achieve configuration synchronization, such as copying the same operational data into the database of the standby machine.
According to the technical scheme, the alternative control devices are added, the configuration of the main control device is synchronized to the alternative control devices, when the main control device goes wrong and goes down, the alternative control device which is the same as the main control device in configuration can replace the main control device at any time, so that the intelligent network management system continues to work normally, the risk of user data loss is reduced, and the disaster tolerance and the safety of the intelligent network management system are improved.
In an embodiment, when the target information includes operation information when the master control device manages the mesh point device, an operation corresponding to the operation information is executed to obtain data configured when the master control device manages the mesh point device, and the data is stored.
In this embodiment, the operation information may be a class, a method, and a parameter corresponding to the operation of the host, and when the host performs an operation of changing the configuration of the host while managing a website, the host may transmit the class, the method, the parameter, and other information corresponding to the operation to the standby through the webservice interface, and then the standby executes the same operation as that on the host by calling the corresponding class, the method, the parameter, and the like, so as to achieve synchronization in configuration.
For example, when a network point is added to the host, the class is the network point, the host calls an addNetwork method, wherein the parameters include network point name, network point key, the organization relationship of the network point, and the like, and the following information is sent to the host: class (c): the method comprises the following steps: addNetwork, parameters: the method comprises the steps that information of network points such as network point names, network point keys and organization relations of the network points is converted into a json format, the json format can transmit data quickly, operation information in the json format is sent to a standby machine, the standby machine can call an addNetwork method by using a Java reflection mechanism after receiving the operation information, then the information of the network points is used as parameters to be executed, configuration information of the standby machine is changed into configuration information the same as that of a host machine in the execution process of the operation, the network point configuration the same as that of the host machine is added to the standby machine, and in the process, the standby machine does not perform information interaction with the newly added network points.
As shown in fig. 2, fig. 2 is a flowchart illustrating a method for information synchronization, which may be used in an alternative control device, according to an embodiment of the present disclosure, and includes the following steps. Wherein the same steps as in the flow of fig. 1 will not be described in detail.
Step S21, receiving target information sent by a master control device, where the target information is associated information when the master control device manages a website device.
Step S22, when the target information includes the status information of the mesh point device managed by the master device, updating information corresponding to the mesh point device based on the target information.
When the host manages the network points, the managed network point device transmits message data to the host, and the host analyzes fields of the message data to obtain state information of the corresponding network points, such as network point online or offline information, network point traffic state information, online authentication user information, state information of switches and wireless access nodes (APs) corresponding to the network points, and the like, so as to monitor the operation state of the network points. And the host sends the state information of the network point devices to the standby machine. For example, the state information converted into json format is transmitted to the standby machine through the webservice interface. And after the standby machine receives the state information of the network point equipment, updating the information of the corresponding network point equipment in the data table to enable the standby machine to reach the same state as the host machine.
In an embodiment, when the target information includes file information when the master control device manages the mesh point device, the file information is saved.
The file information can be information held by a host, such as log file information, version file information, configuration file information and the like, and the file information can be converted into a binary file stream for transmission because FTP transmission is not allowed in general. The file information can be synchronized by the host computer storing the files in the memory into the Stringbuffer by reading the files line by using the IO stream, then converting the files into String types, and transmitting the Stringtypes to the standby computer through the webservice interface. And after receiving the String type file information, the standby machine converts the String type file information into an IO stream to be written into a memory and stores the IO stream.
In an embodiment, when it is determined that target information of a transmission failure exists between the master device and the master device, the target information of the transmission failure is acquired.
When the host sends various target information to the standby machine, a transmission failure condition may occur, and at this time, the host stores the target information with the transmission failure in a persistent mode as a local file. The standby machine can detect whether the target information which is failed to be transmitted to the standby machine exists in the host machine at regular time, and under the condition that the target information which is failed to be transmitted exists in the host machine, the standby machine can acquire the target information which is failed to be transmitted, namely a local file, so that data can be synchronized better, and the risk of user data loss is reduced.
In an embodiment, the number of the alternative control devices may be multiple, each of the alternative control devices may implement the method, when the main control device fails, one of the alternative control devices may be selected according to an initial priority or a default setting to replace the main control device, so that the intelligent node management system continues to operate normally, and the other alternative control devices continue to execute the method.
As shown in fig. 3, fig. 3 is a flowchart illustrating a method for synchronizing information, which may be used for a master device, according to an embodiment of the present disclosure, and includes the following steps. Wherein, the steps repeated with the alternative control device side are not detailed.
Step S31, sending target information to an alternative control device, where the target information is associated information when the master control device manages the mesh point device, and the target information includes operation information when the master control device manages the mesh point device.
When the host manages the network node device, the configuration and other information of the host are continuously enriched and updated, and in order to synchronize the states of the standby machine and the host in various aspects, the host sends target information to the standby machine, that is, the associated information of the host when managing the network node device, and the associated information may include: operation information of the host, state information of the network points, configuration information, file information and other various information related to the host. So that the standby machine can be configured synchronously with the host machine after receiving the target information. One or more standby machines can be provided.
According to the technical scheme, the alternative control devices are added, the configuration of the main control device is synchronized to the alternative control devices, when the main control device goes wrong and goes down, the alternative control device which is the same as the main control device in configuration can replace the main control device at any time, so that the intelligent network management system continues to work normally, the risk of user data loss is reduced, and the disaster tolerance and the safety of the intelligent network management system are improved.
As shown in fig. 4, fig. 4 is a flowchart of another method for synchronizing information, which may be used for a master device and includes the following steps:
step S41, analyzing the message sent by the node device, and obtaining the state information of the node device.
Before this step, the network point interacts with the host machine through HTTP protocol and joins in the intelligent network point management system, it can be the network point initiates a HTTP request, establishes a TCP connection of the appointed port with the host machine, after the host machine receives the HTTP request, it returns 'HTTP/1.1200 OK' to the network point, at this moment, the network point joins in the intelligent network point management system successfully. The network node equipment transmits the message data to the host, and the host can obtain the state information of the corresponding network node by analyzing the field of the message data.
Step S42, sending target information including status information of the mesh point device to the alternative control device.
The host computer sends the state information of the network point devices to the standby computer, so that the standby computer updates the information of the corresponding network point devices in the data table after receiving the state information of the network point devices, and the standby computer achieves the same state as the host computer.
In one embodiment, the host sends the file information inherent or newly generated in the memory to the standby machine, which may be log file information, version file information, configuration file information, etc.
In one embodiment, the host may fail to transmit various target information to the standby device, and the host may persistently store the target information that failed to be transmitted as a local file.
