Detailed Description
The technical contents of the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
When a newly added service configuration item needs to be added in a network management system, in order to develop the same data maintenance module of different services, the data maintenance template codes need to be multiplexed, so that the development time of a large amount of repeated codes is reduced, and the software development efficiency is improved. Therefore, the invention provides a network management system data maintenance method, which mainly aims at maintaining network element equipment side data and network management system side data corresponding to an original service configuration item or a newly added service configuration item in a network management system. As shown in fig. 1, the method for maintaining data in the network management system includes the following steps:
step S1: the obtained network element equipment side data and the network management system side data are arranged in an ascending order according to a certain index field;
when no new service configuration item is added in the network management system, the configuration information can be changed on the existing service configuration file with the format of XML according to the actual requirements of users, for example, the index fields in the network management system side data and the network element equipment side data can be changed. After the configuration information is changed on the existing service configuration file with the format of XML, the network management system is started to obtain the network element equipment side data and the network management system side data. Because the network element equipment side data and the network management system side data both comprise a plurality of elements, each element comprises a plurality of fields, and the plurality of fields of each element comprise an index field, namely each element comprises an index field; according to the index field, a plurality of elements in the network element equipment side data and the network management system side data can be respectively arranged in an ascending order.
When a newly added service configuration item needs to be added in the network management system, the acquired network element equipment side data and network management system side data corresponding to the newly added service configuration item need to be arranged in an ascending order according to a certain index field; the implementation method comprises the following steps:
step S11: adding a newly added service configuration item in a configuration file with an XML format according to a certain rule;
when a newly added service configuration item is added in a configuration file with an XML format, a Group < Group > tag corresponding to the newly added service in the configuration file with the XML format needs to be found, and a unique identifier rmid corresponding to the Group < Group > tag where the newly added service is located is determined; when the configuration file of the XML has the Group < Group > tag corresponding to the newly added service, the Group < Group > tag corresponds to the unique identifier rmid. When the < Group > tag of the Group corresponding to the newly added service does not exist in the configuration file of the XML, firstly, the < Group > tag of the Group corresponding to the newly added service can be added, and the < Group > tag of the Group corresponding to the newly added service is defined to correspond to the unique identifier rmid; and then adding a Function < Function > tag of a newly added service in the added Group < Group > tag, adding a unique identifier rmid corresponding to the newly added service, a memory object of the service, a service correspondence table, a service correspondence index field and a service correspondence comparison field in the Function < Function > tag, and separating the added contents by using separators. By determining the unique identifiers rmid of the different newly added services, the subsequent network management system can conveniently obtain the configuration information of the different newly added service configuration items.
Step S12: reading data of the newly added service configuration item in the XML configuration file and carrying out data verification to obtain configuration information of the newly added service configuration item;
and after the network management system is started, reading the data of the newly added service configuration item in the XML configuration file, checking the read data of the newly added service configuration item, and acquiring the configuration information of the newly added service configuration item according to the unique identifier rmid of the newly added service. The configuration information of the newly added service configuration item includes a memory object of the service, a service correspondence table, a service correspondence index field, and a service correspondence comparison field.
Step S13: acquiring network element equipment side data and network management system side data corresponding to the newly added service configuration item according to the acquired configuration information of the newly added service configuration item;
and calling different objects by using a reflection technology to read data sources in different newly added service configuration items, wherein the data sources refer to network element equipment side data and network management system side data corresponding to the newly added service configuration items. Respectively converting the acquired network element equipment side data and the acquired network management system side data into a universal character string set separated by using separators, wherein the network element equipment side data and the network management system side data both comprise a plurality of elements, namely each element exists in a character string form; each element comprises a plurality of fields, and the fields of each element comprise an index field, namely each element comprises an index field; according to the index field, a plurality of elements in the network element equipment side data and the network management system side data can be respectively arranged in an ascending order.
Step S2: respectively extracting index values of index fields corresponding to each element according to the arrangement sequence of a plurality of elements in the network element equipment side data and the network management system side data;
since each element in the network element device side data and the network management system side data includes an index field, and each index field corresponds to an index value, according to the arrangement order of the elements in the network element device side data and the network management system side data determined in step S1, the index values corresponding to the index fields of each element in the network element device side data and the network management system side data are respectively and sequentially extracted, and two adjacent index values are spliced by using a special separator.
Step S3: traversing all elements in the network element equipment side data and the network management system side data by adopting a double pointer downward movement method, determining whether the network element equipment side data is consistent with the network management system side data, and storing a traversal result in a network management database;
and traversing all elements in the network element equipment side data and the network management system side data by adopting a double pointer downward moving method to determine whether the network element equipment side data is consistent with the network management system side data. The specific method comprises the following steps: as shown in fig. 2, a network management system side pointer (localTableIndex) is used to traverse each element in the network management system side data determined in step S1, and a network element device side pointer (agentTableIndex) is used to traverse each element in the network element device side data determined in step S1; and when all fields of the last element synchronously traversed by the network management system side pointer and the network element equipment side pointer are the same, the network management system side pointer and the network element equipment side pointer can synchronously traverse the next element. And determining whether the network element equipment side data is consistent with the network management system side data according to the obtained traversal result of the network management system side pointer and the network element equipment side pointer, and storing the traversal result in a network management database in a table form, so as to judge whether the network element equipment is normally operated, and a user can directly look up the conditions of each network element equipment.
As shown in fig. 2, the traversal result of the network management system side pointer and the network element device side pointer includes the following situations:
(1) if the network element equipment side pointer and the network management system side pointer both reach the maximum value (the network element equipment side pointer and the network management system side pointer both traverse to the last element in the respective data), the record is that the network element equipment side data is consistent with the network management system side data, which indicates that the network element equipment is operating normally.
(2) If the network element equipment side pointer reaches the maximum value (the network element equipment side pointer traverses to the last element in the network element equipment side data), and the network management system side pointer does not reach (is smaller than) the maximum value (the network management system side pointer does not traverse to the last element in the network management system side data), recording the maximum value as the network element equipment side missing data; at this time, the network element device side pointer is not changed, and the network management system side pointer continues to move down, that is, the network management system side pointer continues to traverse the next element until the network management system side pointer reaches the maximum value, and the traversal process is exited (the network management system side pointer does not move down any more). Under the condition that the network element equipment side pointer is unchanged (the traversal process is stopped), the elements which are continuously traversed by the network management system side pointer are the elements which are lost (missing data) on the network element equipment side, and all fields of each element which is continuously traversed by the network management system side pointer are respectively recorded, so that a user can conveniently maintain the network management system data according to the condition of the missing data on the network element equipment side.
(3) If the network management system side pointer reaches the maximum value (the network management system side pointer traverses to the last element in the network management system side data), and the network element equipment side pointer does not reach (is smaller than) the maximum value (the network element equipment side pointer does not traverse to the last element in the network element equipment side data), recording the maximum value as the network management system side missing data; at this time, the network management system side pointer is unchanged, and the network element equipment side pointer continues to move down, that is, the network element equipment side pointer continues to traverse the next element until the network element equipment side pointer reaches the maximum value, and the traversal process is exited (the network element equipment side pointer does not move down any more). Under the condition that the network management system side pointer is unchanged (the traversal process is stopped), the elements which are continuously traversed by the network element equipment side pointer are the elements which are lost (missing data) at the network management system side, and all fields of each element which is continuously traversed by the network element equipment side pointer are respectively recorded, so that a user can conveniently maintain the network management system data according to the condition of the missing data at the network management system side.
(4) If the network management system side pointer and the network element device side pointer both do not reach the maximum value, at this time, it needs to compare whether the element of the network management system side data determined in step S1 is consistent with the element of the network element device side data. When the element of the network management system side data is consistent with the element of the network element equipment side data, the network management system side data is recorded to be the same as the network element equipment side data, then the network management system side pointer and the network element equipment side pointer respectively continue to move downwards, namely the network management system side pointer and the network element equipment side pointer continue to synchronously traverse the next element until the network management system side pointer and the network element equipment side pointer both reach the maximum value, and the traversal process is exited (the network management system side pointer and the network element equipment side pointer do not move downwards any more).
When the element of the network management system side data is inconsistent with the element of the network element device side data, it is necessary to compare whether the index values in the network management system side data extracted in step S2 are consistent with the index values in the network element device side data extracted in step S2. When the index values in the data at the network management system side are consistent with the index values in the data at the network element equipment side, recording that the data at the network management system side and the data at the network element equipment side have difference data, and recording all fields of elements which specifically have difference in the data at the network management system side and the data at the network element equipment side, so that a user can conveniently check the difference data condition existing in the data at the network management system side and the data at the network element equipment side. Then, the network management system side pointer and the network element equipment side pointer respectively continue to move down, that is, the network management system side pointer and the network element equipment side pointer continue to synchronously traverse the next element until the network management system side pointer and the network element equipment side pointer both reach the maximum value, and the traversal process is exited (the network management system side pointer and the network element equipment side pointer do not move down any more). In the process, all fields of the elements in the network management system side data corresponding to the elements with differences in the network element equipment side data are respectively recorded by sequentially comparing whether all fields of the elements in the network management system side data are consistent with all fields of the corresponding elements in the network element equipment side data, so that a user can conveniently maintain the network management system data according to the difference data condition of the network management system side data and the network element equipment side data.
When the index values in the network management system side data are inconsistent with the index values in the network element equipment side data, if the number of the index values in the network management system side data is larger than the number of the index values in the network element equipment side data, recording the index values as the network element equipment side missing data. At this time, the network element device side pointer is not changed, and the network management system side pointer continues to move down, that is, the network management system side pointer continues to traverse the next element until the network management system side pointer reaches the maximum value, and the traversal process is exited (the network management system side pointer does not move down any more). Under the condition that the network element equipment side pointer is unchanged (the traversal process is stopped), the elements which are continuously traversed by the network management system side pointer are the elements which are lost (missing data) on the network element equipment side, and all fields of each element which is continuously traversed by the network management system side pointer are respectively recorded, so that a user can conveniently maintain the network management system data according to the condition of the missing data on the network element equipment side. If the number of the index values in the network element equipment side data is larger than the number of the index values in the network management system side data, recording as network management system side missing data. At this time, the network management system side pointer is unchanged, and the network element equipment side pointer continues to move down, that is, the network element equipment side pointer continues to traverse the next element until the network element equipment side pointer reaches the maximum value, and the traversal process is exited (the network element equipment side pointer does not move down any more). Under the condition that the network management system side pointer is unchanged (the traversal process is stopped), the elements which are continuously traversed by the network element equipment side pointer are the elements which are lost (missing data) at the network management system side, and all fields of each element which is continuously traversed by the network element equipment side pointer are respectively recorded, so that a user can conveniently maintain the network management system data according to the condition of the missing data at the network management system side.
Step S4: and maintaining the network management system data according to the traversal result of the network management system side data and the network element equipment side data stored in the network management database.
Because the result of traversing the network element equipment side data and the network management system side data by adopting the double pointer downward movement method is stored in the network management database in the form of a table in step S3, the user can judge the operation state of the network element equipment according to the traversal result of the network management system side data and the network element equipment side data stored in the consulted network management database, and the network element equipment can normally operate by maintaining the network management system data.
For example, as shown in fig. 3, taking the traversal result of the network element device side data and the network element system side data corresponding to the four service configuration items stored in the network management database as an example, in the traversal result, the sequence numbers represent the sequence numbers of the elements in the network management system side data and the network element device side data respectively, and all fields of each element in the network management system side data and the network element device side data respectively represent the user attribution name, the subnet, the mask, and the user attribution service address. It can be easily seen that the data at the network element equipment side corresponding to the first service configuration item is the same as the data at the network management system side; the fourth element in the network element equipment side data and the network management system side data corresponding to the second service configuration item is inconsistent, and the fields which represent the user attribution names in the network management system side data and the fourth element in the network element equipment side data are inconsistent; in the network element equipment side data and the network management system side data corresponding to the third service configuration item, the network element equipment side data lacks a fifth element in the network management system side data; in the network element equipment side data and the network management system side data corresponding to the fourth service configuration item, the network management system side data lacks a sixth element in the network element equipment side data; therefore, it can be preliminarily determined that except the network element device corresponding to the first service configuration item, the network element devices corresponding to the remaining three service configuration items all have certain problems in operation status, and data thereof needs to be maintained. Then, the user needs to maintain the network management system data (network management system side data and each network element device side data) according to the traversal result presented in fig. 3 and in combination with the original data of the network management system. For example, the original data of the network management system may be compared with the fourth element in the network element device side data and the network management system side data corresponding to the second service configuration item, so that the network element device side data and the network management system side data are consistent, and the normal operation of the network element device is ensured. If the fifth element does exist in the network element equipment side data corresponding to the third service configuration item in the original data of the network management system, the fifth element in the network management system side data can be copied into the network element equipment side data, so that the network element equipment side data and the network management system side data are consistent, and the normal operation of the network element equipment is ensured; if the fifth element does not exist in the original data of the network management system in the network element equipment side data corresponding to the third service configuration item originally, the fifth element in the network management system side data can be deleted, so that the network element equipment side data and the network management system side data are consistent, and the normal operation of the network element equipment is ensured. The method for maintaining the network element device side data and the network management system side data corresponding to the fourth service configuration item refers to the network element device side data and the network management system side data corresponding to the third service configuration item, and is not described herein again.
The network management system data maintenance method provided by the invention adopts a double pointer downward moving method to traverse all elements in the network element equipment side data and the network management system side data, determines whether the network element equipment side data is consistent with the network management system side data, and stores the traversing result in the network management database, so that a user can directly look up the operation condition of each network element equipment and maintain the network management system data.
