In step S22 in Fig. 2, the judgment module 10 judges whether the network device configuration file is obtained for the first time.

In step S23 in Figure 2, if the judgment module 10 judges that the network device configuration file is the first to acquire, the user side uses the display module 17 to mark the network device configuration file. At least one block to form a new configuration template file, and then store the new configuration template file in the first database 12, and then the processing module 13 sets the configuration template file to form a new device configuration file, The new device configuration file is then stored in the first database 12, and the new device configuration file is used to record parameter information of at least one block of the new configuration template file.

In step S24 of Fig. 2, if the judgment module 10 judges that the network device configuration file is not obtained for the first time, the matching module 11 obtains the corresponding network from the first database 12 The configuration template file of the device configuration file and the device configuration file, and the matching module compares the network device configuration file with the configuration template file and the device configuration file to see if they match.

In step S25 in Figure 2, if the network device configuration file matches the configuration template file and the device configuration file, the matching module 11 marks at least one block in the network device configuration file that matches To form a new configuration template file, and then store the new configuration template file in the first database 12, and then the processing module 13 sets the new configuration template file to form a new device configuration file, and then the new configuration template file The equipment configuration file is stored in the first database 12.

In step S26 in Figure 2, the comparison change notification module 14 compares at least one of the new configuration template file and the configuration template file in the first database 12 Is there any change in the content of the block? If there is a change, the comparison change notification module 14 informs the user that the content of at least one block corresponding to the new configuration template file and the configuration template file has changed; otherwise, If there is no change, the comparison change notification module 14 does not notify the user, and replaces the corresponding configuration template stored in the first database 12 with the new configuration template file and the new device configuration file File and the device configuration document.

Figure 3 is a flow chart of the matching method of the matching module for detecting network device configuration file changes according to the present invention. It can at least include the technical content of the following steps S31 to S38, and refer to Figure 1 below. Explain it.

In step S31 in Figure 3, the configuration template file and the device configuration file corresponding to the network device configuration file are obtained from the first database 12.

In step S32 in Figure 3, the matching module 11 obtains the first range context of at least one block of the configuration template file according to the parameter information of the device configuration file to compare the network device configuration file one by one. Within the context, and the retrieval algorithm for the context location block calculates the matching rate of the first range context of the network device configuration file.

In step S33 in FIG. 3, the matching module 11 compares whether the matching rate of the first range context of the network device configuration file is greater than or equal to a critical value.

In step S34 in Figure 3, if the matching rate of the first range context is greater than or equal to the critical value, it means that the configuration template file matches at least one block of the network device configuration file, and then the matching The module 11 marks at least one block of the network device configuration file to form the new configuration template file, and then causes the processing module 13 to set the new configuration template file to form the new device configuration file.

In step S35 of Figure 3, if the matching rate of the first range context is less than the threshold, the matching module 11 expands the context of at least one block of the configuration template file to A second scope context larger than the first scope context is formed, so that the processing module 13 updates the device configuration document according to at least one block of the expanded configuration template file, and locates the block of the related context again The retrieval algorithm calculates the matching rate of the second range context of the network device configuration file according to the second range context.

In step S36 in FIG. 3, the matching module 11 compares whether the matching rate of the second range context of the network device configuration file is greater than or equal to a critical value.

In step S37 in Figure 3, if the matching rate of the second range context is greater than or equal to the critical value, it means that the configuration template file matches at least one block of the network device configuration file, and then the matching The module 11 marks at least one block of the network device configuration file to form the new configuration template file, so that the processing module 13 forms the new device configuration file according to the new configuration template file.

In step S38 in Figure 3, if the match rate of the second range context is less than the threshold, it means that at least one block of the network device configuration file cannot be located, and then the comparison change notification module 14 Notify the user side.

Figure 4 is a flow chart of the comparison and notification method of the comparison change notification module 14 for detecting network device configuration file changes according to the present invention, which may at least include the following technical content from step S41 to step S45, and Refer to Figure 1 below for description.

In step S41 in Figure 4, the comparison change notification module 14 reads at least one block of the new configuration template file and at least one block of the configuration template file.

In step S42 of FIG. 4, the comparison change notification module 14 compares the content of at least one block of the configuration template file based on the content of at least one block of the new configuration template file.

In step S43 in Figure 4, the comparison change notification module 14 compares the contents of at least one block of the configuration template file and the new configuration template file one by one. If the content of at least one block does not exist in the content of at least one block of the new configuration template file, the non-existent sentence will be given a deletion mark, and the deletion mark will be displayed on the new configuration template file; if it is If the content of at least one block of the new configuration template file does not exist in the content of at least one block of the configuration template file, the non-existent sentence will be given a new mark, and the new mark will be displayed in the new group And then form a block comparison result.

In step S44 in FIG. 4, the comparison change notification module 14 determines whether there is a mark to add a mark or/and to delete a mark. If the comparison change notification module 14 determines that there is a mark to add a mark or/and a delete mark, it proceeds to step S45 to notify the user that at least one block of the new configuration template file has changed; otherwise, If there is no mark to add a mark or/and delete a mark, there is no need to notify the user end, and the process goes directly to step S46.

In step S46 in Figure 4, the comparison change notification module 14 replaces the new configuration template file and the new device configuration file with the corresponding configuration template file and the device stored in the first database 12 Configuration document.

Please refer to Figure 5A and Figure 5B, which are schematic diagrams of the configuration template file and the device configuration file of the present invention. In one embodiment, when the network device configuration file is obtained for the first time, the stored network device configuration file is retrieved from the second database 16 and the first database 12 is checked to see if there is a corresponding If the configuration template file does not exist, mark the device configuration file, and insert the tag symbol "#(flag)" at the beginning of the sentence in the device configuration file that the user is concerned about to form at least one Blocks (Block1, Block2), when the user finishes marking, the new configuration template file is generated, as shown in Figure 5A, and stored in the first database 12, and then the processing module 13 according to the new configuration The template file is used for the reference of the new device configuration document. Number information settings. Then determine the ``neighbor k'' of the context range and the conditions required to formulate the matching rate of at least one block context ``Upper Match Ratio (UMR)'' and ``Lower Match Ratio (Lower Match Ratio)''. Ratio, LMR)” and other parameters, where “k” is an arbitrary value set on the user side, and the parameter information of the device configuration file is described in Table 1, and the device configuration file is generated, as shown in As shown in Figure 5B.

Please refer to Fig. 6A and Fig. 6B, which are schematic diagrams of matching the device configuration file and the configuration template file of the present invention. In one embodiment, when the device configuration file is obtained, the corresponding configuration template file and the parameter information of the device configuration file are read, and at least one block of the configuration template file is obtained. Set (Upper Bound Sentences, UBS){UBS[1],...,UBS[k]}, below set (Lower Bound Sentences,LBS){LBS[1],...,LBS[k]}, such as As shown in Figures 6A and 6B, the contextual set (as shown in Figure 6A and Figure 6B) of each block (such as Block1 and Block2 in Figure 6A and Figure 6B) is extracted using the extraction algorithm of the relevant context positioning block. UBS1, LBS1, UBS2, and LBS2) in Figure 6B are based on the above set of at least one block of the configuration template file in order to search for the above set and the following set on the device configuration file. And substitute the searched sentences into the above matching rate (UMR) formula (such as formula (1)) and the below matching rate (LMR) formula (such as formula (2)) in sequence, as shown in "Match (UBS _n [i])Count" represents the "number of matches above" and "Match(LBS _n [i])Count" represents the "number of matches below".

Therefore, calculate the above matching rate (UMR) and the below matching rate (LMR) of at least one block of the device configuration file, that is, calculate the context set (UBS, LBS) to match in the device configuration file The matching rate of the sentence. In the process, if the calculation result meets the context matching rate (UBS, LBS) greater than or equal to the preset threshold, it can be regarded as the content sentence contained in the context set (UBS, LBS), which is The block to be compared and taken out, and so on until the last block is taken out completely, and finally the new configuration template file is formed.

Figures 7A and 7B are schematic diagrams of a new configuration template file formed by the network device configuration file of the present invention. In one embodiment, first, assuming that the context matching rate threshold is 80%, when the network device configuration file is obtained, the extraction algorithm of the relevant context location block is used to calculate at least the value of the configuration template file. The matching rate of the above set 101, 201 and the following set 102, 202 of a block 100, 200, so calculate UMR1=10 (number of matches)/10(k) * 100%=100%, LMR1=1 (match Number)/1(k) * 100%=100%; UMR1>=80% (critical value) and LMR1>=80% (critical value). Therefore, if it meets the critical value of the context match rate, it can be regarded as the above The set 101, 201 and the following set 102, 202 contain content sentences, which are the at least one block 100, 200 to be compared, and take it out, and so on until the last block 100, 200 is completely taken out , And finally form the new configuration template file.

In this embodiment, if the context matching rate (UBS, LBS) of at least one block of the network device configuration file is less than the critical value and the matching rate is greater than 60%, then the extended set formula [Bias(b)] ( Such as formula (3)).

Bias(b)=Max{(k-Match(UBS _n )Count),(Match(UBS _n )Count)}*2 (3)

Then, calculate the maximum *2 times of the "non-matching number {k-Match(UBS _n )Count}" and "matching number {Match(UBS _n )Count}", and expand the above set by using this formula value With the following set, covering more contextual sentences to match, recalculating the contextual match rate, the extended sentence is sequentially substituted into the extended upper bound match ratio (Extension Upper Bound Match Ratio, eUMR) formula (such as formula (4) )) and the extension lower bound match ratio (eLMR) formula (such as formula (5)), where b is the number of extended context lines.

This purpose is mainly to enhance the accuracy of positioning and avoid the possibility of unmatching due to excessive content changes in the context collection. If the recalculated extended context matching rate reaches the critical value, then the at least one block is taken out. If the critical value is still not met, it means that the at least one block cannot be located. Therefore, at least one block of the network device configuration file this time The content of the block may be removed.

Figure 8 is a schematic diagram of the expanded device configuration file of the present invention. In one embodiment, first, assuming that the context matching rate condition is 80%, when a block 300 of the network device configuration file is obtained, the extraction algorithm of the relevant context location block is used to calculate the configuration template The matching rate of the above set 301 and the following set 302 of a block 300 of the document is calculated UMR=2 (number of matches)/3(k) * 100%=67%, LMR=3 (number of matches)/5(k) * 100%=60%, UMR and LMR<80% (critical value) , Therefore, substituting the extended set formula (Bias), Bias(b)=Max(1,2) * 2=4 in the extended set 303 above, and Bias(b)=Max(2,3) * in the extended set 304 below 2=6. At this time, recalculate the matching rate, and get eUMR=7 (number of matches)/8(k+b) * 100%=87.5%, eLMR=9 (number of matches)/11(k+b) * 100%=81.8 %, eUMR and eLMR>=80% (critical value), so a block 300 of the device configuration file is taken out, and finally the new configuration template file is formed.

Please refer to Figures 9A, 9B and 10, where Figure 9A is a schematic diagram of the configuration template file of the present invention, Figure 9B is a schematic diagram of the new configuration template file of the present invention, and Figure 10 It is a schematic diagram of the block comparison result of the configuration template file of the present invention and the new configuration template file. As described in the previous paragraph, in one embodiment, at least one block (Block) of the extracted configuration template file is then compared with at least one block (Block) of the new configuration template file, such as As shown in FIG. 9A and FIG. 9B, the content of at least one block (Block) of the new configuration template file is compared based on the content of at least one block (Block) of the new configuration template file. Compare the content of at least one block (Block) of the configuration template file and the new configuration template file one by one. If the content of at least one block (Block) of the configuration template file does not exist In the content of at least one block (Block) of the new configuration template file, the sentence that does not exist will be marked for deletion and displayed on the new configuration template file; if it is at least one area of the new configuration template file If the text of a block does not exist in the text of at least one block of the configuration template file, the non-existent text will be given a new mark and displayed on the new configuration template file. Finally Generate the new configuration template file with the mark addition mark or/and delete mark to form a block comparison result, as shown in Figure 10.

Furthermore, when the block comparison result has the mark addition or/and deletion mark, it means that the content of at least one block (Block) of the configuration template document that the user is concerned about has changed, and Alarm notification to the user side.
