The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 and fig. 2, a cloud computing network device configuration difference comparing method includes the following steps:
s1, configuring an xml format by the equipment, generating a unique hash value by each xml node, and storing the hash value in a key: map1 of value;
s2, generating an xml node through each record of the database elements, wherein each node also generates a hash value which is stored in a key: map2 of value;
s3, comparing by key of Map1 and Map 2;
s4, sequentially traversing the set 1 and the set 2 in a circulating manner;
s5, analyzing whether the keywords of the two xml node nodes are consistent, if so, putting the keywords into a difference list, and removing the keywords from the Map1 and the Map 2;
s6, if the difference is not consistent, respectively keeping the difference in Map1 and Map 2;
and S7, the rest Map1 and Map2 represent the redundant configuration of the equipment and the less-equipment configuration respectively.
Step S1 is used for finding the only corresponding xml node value through the hash value.
The method for comparing Map1 and Map2 by key in step S3 is as follows: the keys of the two maps generate a set 1 and a set 2, and a difference set of the sets is taken, namely different data needing to be compared between the two maps 1 and 2.
The configuration with less devices in step S7 is the configuration with more databases.
As shown in fig. 1, the device agent service is responsible for receiving instructions from the network controller and obtaining configuration information of each module to be compared from the database.
The device agent also needs to obtain the configuration of the modules from the devices in turn, and compare the configuration through a comparison algorithm. Finally, three arrays are generated, wherein one array represents redundant configuration of the device, one array represents configuration with more databases (namely configuration with less devices), and one array stores different configurations of the device and non-critical fields of the configuration of the databases.
Since the format returned by the device is xml format, unlike database format, the design of the comparison algorithm determines the performance of the comparison.
As shown in fig. 2, the device configuration comparison process includes the following steps: 1. the device is configured with an xml format, each xml node generates a unique hash value, and the hash value is stored in a key: in Map1 of value, that is, a unique value (corresponding xml node) can be found through the hash value;
2. generating an xml node through each record of the database element, wherein each node also generates a hash value which is stored in a key: map2 of value;
3. comparing the keys of Map1 and Map2, namely generating a set 1 and a set 2 by the keys of the two maps, and taking the difference set of the sets, namely the different data to be compared of the two maps 1 and Map 2;
4. sequentially traversing the set 1 and the set 2 through circulation;
5. analyzing whether the keywords of the two xml node nodes are consistent, if so, putting the keywords into a difference list, and removing the keywords from Map1 and Map 2;
6. if not, respectively keeping in Map1 and Map 2;
7. the remaining maps 1 and 2 represent the device redundant configuration and the device less configuration (i.e., the database more configuration), respectively.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
