[0061] According to an embodiment of the present invention, a verification method and device for modifying the configuration of a BAS device based on a matching algorithm are proposed. For the configuration file of the modified BAS device, all configuration files including this device in the existing network environment are obtained; through parameter matching and command matching, the configuration parameter range and configuration command rules of the configuration files in the existing network environment are obtained, and the content of the modified configuration file is verified one by one according to the obtained rules, the configurations that do not meet the requirements are marked, and the verification results are promptly fed back to the operation and maintenance personnel.

[0066] According to the area information to which the BAS device belongs, enter the working directory where the configuration files are stored in this area, and sequentially query the working directories where each BAS device is stored to obtain the latest configuration file in the current working directory, which is the existing network configuration file of the BAS device.

[0067] 2. Match the configuration file of the modified BAS device with the in-network configuration file of this BAS device to obtain the different parts between the two, which are the modified contents of the configuration.

[0068] Use a text matching algorithm (prior art) to compare the configuration file of the modified BAS device with the in-network configuration file of this BAS device to obtain the different parts between the two. Taking File A and File B as examples, the different parts include three types: the parts that are redundant in File A compared to File B, the parts that are modified in File A compared to File B, and the parts that are missing in File A compared to File B.

[0076] Extract keywords from the configuration command information of each line in the horizontally different part of the configuration according to the line break identifier, and convert the original command line into a keyword list;

[0077] Traverse the keyword list, record the frequency of occurrence of each command keyword, and obtain the command keyword frequency information table;

[0078] Divide the frequency of occurrence of each command keyword by the total number of command keywords to obtain the command keyword frequency information table;

[0079] Set the minimum frequency threshold, and obtain the list of command keywords with a frequency greater than the threshold, which is the high-frequency change command list.

[0080] 5. Check the configuration parameters and configuration commands for the obtained configuration modification content, and mark the configurations that do not meet the requirements;

If the parameter is not within the value range, it is considered that there is an abnormality in this parameter, and this configuration is marked as <abnormal parameters>; otherwise, this configuration parameter is considered normal.

[0082] Extract keywords from the configuration commands of the obtained configuration modification content, query the high-frequency change command list, and check whether the command is in the list. If the command is not in the list, it is considered that there is an abnormality in this command, and this command is marked as <abnormal orders>; otherwise, this command is considered normal.

[0083] 6. Statistically analyze the verification results in segments and output the final verification results;

[0084] According to the segment identifier of the BAS configuration, perform segment statistics on the configuration modification content, count the number of parameter abnormalities and command abnormalities in each segment, add the statistical information to the beginning of each segment of the configuration modification content, and output the verification results including the statistical information.

[0085] It should be noted that although the operations of the method of the present invention are described in a specific order in the above embodiments and accompanying drawings, this does not require or imply that these operations must be performed in this specific order, or that all the operations shown must be performed to achieve the desired result. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution.

The optimal matching and horizontal difference acquisition sub-module is used to pairwise match all configuration files to obtain the optimal matching file for each configuration file, and summarize the differences between each configuration file and its optimal matching file, which is the horizontal difference. Traverse the configuration files of all BAS devices in the in-network environment, perform pairwise matching using the optimal matching algorithm to obtain the optimal matching file for the configuration file of each BAS device, calculate the difference between the configuration file of the BAS device and its optimal matching file, and summarize the differences between the configuration files of all BAS devices and their optimal matching files to obtain the horizontal difference of the contemporaneous configuration files. The horizontal difference represents the parts that are frequently modified in the configuration files during this period. Optimal matching algorithm: For a certain configuration file, sequentially traverse all other configuration files in the directory, calculate the difference between the configuration file and other configuration files, divide the number of different lines of the two files by the total number of lines of the two files to obtain the difference degree between the two files, and the file with the smallest difference degree is the optimal matching file for the configuration file. The keyword extraction and word frequency statistics sub-module is used to extract keywords from text information using keyword extraction rules and summarize and count the extracted keywords. Extract keywords from the configuration command information of each line of the horizontal difference part of the configuration according to the line break identifier, and convert the original command line into a keyword list. Traverse the keyword list, record the frequency of occurrence of each command keyword, and obtain the command keyword frequency information table; Divide the frequency of occurrence of each command keyword by the total number of command keywords to obtain the command keyword frequency information table; Set the minimum frequency threshold, and obtain the list of command keywords with a frequency greater than the threshold, which is the high-frequency change command list. Configure the verification module 105 to verify the configuration parameters and configuration commands for the obtained configuration modification content, and mark the configurations that do not meet the requirements; The configuration verification includes two aspects. On the one hand, verify whether the configured parameters exceed the range according to the configuration parameter value range table. On the other hand, verify whether the configuration command is a frequently modified command according to the high-frequency change command list; Perform configuration parameter matching on the obtained configuration modification content, obtain the parameter value of the configuration modification content and the configuration command after parameter replacement, then query the configuration parameter value range table to verify whether the parameter is within the value range. If the parameter is not within the value range, it is considered that there is an abnormality in this parameter, and this configuration is marked as <abnormal parameters>; otherwise, this configuration parameter is considered normal. Extract keywords from the configuration command of the obtained configuration modification content, query the high-frequency change command list, and verify whether the command is in the list. If the command is not in the list, it is considered that there is an abnormality in this command, and this command is marked as <abnormal orders>; otherwise, this command is considered normal. The result output module 106 is used to statistically analyze the verification results in segments and output the final verification results; According to the segmentation identifier configured by BAS, perform segmented statistics on the configuration modification content, count the number of parameter abnormalities and command abnormalities in each segment, add the statistical information to the beginning of each segment of the configuration modification content, and output the verification results including the statistical information.
