Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Files are currently commonly used to store configuration information that is orders of magnitude backed up, of high importance, and frequently updated: when the configuration information is issued, the configuration information is enabled to take effect, and simultaneously, the configuration information is written into a configuration file for backup in real time; when the configuration information is deleted, the configuration information is also deleted from the configuration file in real time; and under the condition of restarting or hot plugging of the equipment, reading the configuration file and transmitting all the configuration information to the equipment from beginning to end.
The configuration information backup method based on the file storage can store the configuration information in real time, and the configuration file is modified each time the configuration information is added, so that the performance of issuing the configuration information is reduced to a certain extent, and particularly under the condition of high-frequency configuration information updating, the reaction speed of network equipment is obviously slowed down, and the user experience is poor. Moreover, if the configuration information is deleted in real time, other useful device information may be deleted by mistake when the device is operated for a long time, in a multi-thread manner, and at a high frequency, and the configuration information may be lost. Therefore, the existing configuration information backup method causes potential safety hazards while reducing the performance of the equipment. Based on this, the embodiment of the invention provides a configuration information backup method, a configuration information backup device and network equipment, which can perform storage backup on configurations with large magnitude, high importance and frequent update with higher performance and higher security.
To facilitate understanding of the embodiment, a detailed description is first given of a configuration information backup method disclosed in the embodiment of the present invention.
The embodiment of the invention provides a configuration information backup method, which is applied to network equipment stored with bitmap information, wherein the bitmap information is used for indicating the storage position of rule table item configuration information in a configuration file. Referring to fig. 1, a schematic flow chart of a configuration information backup method is shown, and the method mainly includes the following steps S102 to S106:
step S102, monitoring whether new rule table item configuration information is issued within a preset time length.
The preset duration can be set according to actual requirements, and is not limited here. In specific implementation, the thread can be independently started, and a timer is set in the thread to monitor the network device.
And step S104, when the monitoring result is yes, updating the bitmap information, and sending the new rule table item configuration information to a content addressable memory on a service board card of the network equipment so as to enable the new rule table item configuration information to take effect.
And resetting the time of the timer after finding that the new rule table item configuration information is issued. When the device issues the rule table configuration information, the configuration information is stored in the memory, and the configuration information may be issued to the kernel of the device first. And setting bitmap information in the kernel, and setting the bitmap position corresponding to the corresponding configuration information. And then, the configuration information is issued to a content addressable memory on the service board card by the kernel, so that the issued configuration information can take effect immediately, rather than writing the configuration information into a configuration file in real time for storage and backup.
In some possible embodiments, the first bitmap position corresponding to the new rule table entry configuration information may be set to obtain updated bitmap information; wherein the first bitmap is used for indicating the storage location of the new rule table entry configuration information in the configuration file.
Further, in order to reduce the operation of repeatedly writing the configuration file and improve the efficiency of writing the configuration file, another bitmap (second bitmap) may be used to indicate whether the rule table entry configuration information stored in the memory is consistent with the corresponding rule table entry configuration information in the configuration file. Based on this, after setting the first bitmap position corresponding to the new rule table entry configuration information, the method further includes: setting the position of a second bitmap corresponding to the new rule table item configuration information to obtain updated bitmap information; wherein, the second bitmap is used for indicating whether the new rule table item configuration information is successfully written into the configuration file.
For example, when the rule table configuration information is updated, the corresponding position is set to 1, after the rule table configuration information is successfully written into the configuration file, the corresponding position is set to 0, and only the rule table configuration information corresponding to the bitmap with 1 set is written into the configuration file.
And step S106, writing the first configuration information to be backed up in the network equipment into the configuration file according to the bitmap information when the monitoring result is negative.
For the rule table item configuration information which is large in storage and recovery magnitude, high in importance and frequent in updating, if the rule table item configuration information is stored in a configuration file in a binary mode, the storage performance and the reading performance of the rule table item configuration information are far higher than those of a text file, the size of the binary file is fixed, and the rule table item configuration information can be quickly positioned to the position of certain configuration information in the configuration file, so that the rule table item configuration information can be stored and backed up based on the binary file for file storage.
Based on this, in some possible embodiments, the step S106 may be implemented by the following process: determining each rule table item configuration information with a second bitmap position of 1 in the bitmap information as first configuration information to be backed up; determining a position parameter of the first configuration information in the configuration file according to the first bitmap position information corresponding to the first configuration information; writing the first configuration information into a configuration file in a binary mode according to the position parameter; and resetting the position of the second bitmap corresponding to the first configuration information in the bitmap information when the writing is successful.
In the concrete implementation, if no new rule item configuration information is issued to the equipment within a certain time, the rule item configuration information and bitmap information which need to be configured and restored in the equipment are written into the corresponding positions in the configuration file by using a binary system. Because the size of each rule table item configuration information of the same type is fixed in a binary system, the position parameters of the configuration information in the configuration file can be directly and accurately calculated through a fixed formula according to bitmap information, the corresponding storage position can be positioned according to the time complexity of O (1) and written, and the rule table item configuration information of different types is written in different configuration files.
In the embodiment of the invention, when the configuration information is backed up, whether new rule table item configuration information is issued within a preset time length is monitored; when the monitoring result is yes, updating bitmap information, and issuing new rule table item configuration information to a content addressable memory on a service board card of the network equipment so as to enable the new rule table item configuration information to take effect; and when the monitoring result is negative, writing the first configuration information to be backed up in the network equipment into the configuration file according to the bitmap information. Therefore, when the rule table item configuration information is issued, the configuration information is not written into the configuration file for backup immediately, but is directly issued to the content addressable memory to be effective in the equipment, so that the time spent on issuing the rule table item configuration information is reduced, and the equipment performance for issuing the configuration information is improved; and the rule table item configuration information is stored to the configuration file at regular time, so that the peak of the use of the equipment can be staggered, the time complexity is low, and the reduction of the equipment performance caused by issuing the rule table item configuration information for many times at high frequency is effectively reduced. Therefore, the configuration information backup method provided by the embodiment of the invention improves the performance of the equipment for issuing the configuration information, thereby improving the user experience.
Further, the method further comprises: when a configuration information deleting instruction is received, second configuration information to be deleted is obtained; resetting a first bitmap position corresponding to the second configuration information in the bitmap information; deleting the second configuration information in the content addressable storage to effect deletion of the second configuration information.
In the concrete implementation, if the operation of deleting the rule table entry configuration information is being performed during the file writing, the bitmap corresponding to the corresponding configuration information is set again (namely reset) in the kernel, and then the corresponding configuration information in the content addressable memory is deleted, so that the deleted configuration information is immediately effective, but the corresponding rule table entry configuration information stored in the configuration file is not required to be deleted.
Because the equipment does not delete the corresponding information in the configuration file when deleting the rule table entry configuration information, and only sets the bitmap, the content loss or errors possibly caused by frequently modifying the file are reduced, the file reading and writing times are reduced, the performance optimization is brought, and the accuracy of the configuration file information is improved.
Optionally, a timer is used to monitor whether to issue new rule table entry configuration information within a preset time duration, and based on this, the method further includes: when a restart instruction is received, closing a timer; writing first configuration information to be backed up in the network equipment into a configuration file according to the bitmap information; and restarting the network equipment.
After the device receives the restart instruction, the device does not directly execute the shutdown restart operation, but closes the timer, invokes a function of storing the rule table entry configuration information (i.e., a configuration storage function), updates the configuration information and bitmap information in the device into a configuration file, and after the rule table entry configuration information is stored and backed up, the device executes the subsequent shutdown restart operation.
The configuration storage function is directly called before the rule table item configuration information is restarted, so that the problem that the important rule table item configuration information is lost due to the fact that the rule table item configuration information is not stored timely because the timer does not run out can be solved, and the safety performance is improved.
Further, the method further comprises: reading bitmap information when a configuration recovery instruction is received; reading third configuration information to be issued in the configuration file according to the bitmap information; and sending the third configuration information to the content addressable storage.
After the equipment is restarted or the card is unplugged, and the like, configuration recovery based on the whole machine or the single card is required to be executed, at this time, bitmap information of the rule table item configuration information is read first, similarly, the position information of the rule table item configuration information in the configuration file can be accurately calculated through the same calculation formula according to the bitmap information, then the configuration information of the corresponding position is accurately positioned and read according to the time complexity of O (1), and the read rule table item configuration information is re-issued to a content addressable memory of the equipment, so that the corresponding configuration information is enabled to take effect again on the equipment.
When the rule table item configuration is recovered, the mode of acquiring the position of the rule table item configuration information to be issued in the configuration file from the bitmap information can prevent the issuing of the unnecessary configuration information and improve the authenticity of the equipment configuration information.
Further, a fixed length version number may be added to the header of the configuration file to determine the version of the configuration file. When the format or meaning of the rule field in the configuration file is changed, the version number is updated. The way in which all earlier versions are parsed can be retained by the software program so that all earlier versions of the configuration file can be correctly identified. When the device is started, if the version of the current configuration file is not the latest version, the current configuration file can be converted into the format of the latest version so as to facilitate the subsequent configuration update.
In order to facilitate understanding of location of configuration information in a configuration file, an embodiment of the present invention further provides an example of a configuration file, and referring to a schematic diagram of a configuration file shown in fig. 2, where a version number is 4, and a single rule entry configuration information is 152, a position of the 1 st rule entry configuration information in the configuration file is 4, a position of the 2 nd rule entry configuration information in the configuration file is 152 × 1+4, and similarly, a position of the n-th rule entry configuration information in the configuration file is 152 × (n-1) +4.
The operations provided by the embodiment of the invention aim to reduce the times of reading and writing files, extend the performance pressure of the equipment according to time, greatly improve the safety performance while improving the performance, and have no influence on the normal function of the equipment.
To sum up, the method for backing up configuration information based on file storage according to the embodiment of the present invention first sets a bitmap and a distribution logic when distributing rule table entry configuration information, and writes configuration information to a configuration file for storage at regular time after the rule table entry configuration information is frequently distributed; when deleting the rule table item configuration information, not deleting the configuration information in the configuration file, only setting a bitmap, and checking the bitmap before operating the file; the position of the configuration information in the configuration file is calculated through the bitmap information and the fixed formula, the time complexity is in a constant level, the times of reading and writing the file are greatly reduced, and the performance and the safety of storage backup and recovery of the rule table item configuration information which is large in order of magnitude, high in importance and frequent in updating are effectively improved.
Corresponding to the above configuration information backup method, an embodiment of the present invention further provides a configuration information backup apparatus, where the apparatus is applied to a network device that stores bitmap information, and the bitmap information is used to indicate a storage location of rule table entry configuration information in a configuration file.
