Description

  The present invention relates to a maintenance operation program, and more particularly to a maintenance operation program for maintaining and operating a plurality of network elements.

  In a communication network, maintenance operation of network elements (for example, a transmission device that communicates between communication networks) is performed in order to achieve highly reliable communication. In the network element maintenance and operation system, each network element is connected to a server, and maintenance and operation of each network element is performed by an operator from a terminal device.

  FIG. 10 is a configuration diagram of a conventional maintenance operation system. As shown in the figure, terminal devices 111a, 111b,..., 111n are connected to the maintenance server 100. Further, for example, a network element (NE) managed for each station is connected to the maintenance operation server 100 via a network 121 which is a LAN (Local Area Network). ing. The station A has NEs 131a, 131b,..., 131n as shown (the NEs of the stations B, C,... Are not shown).

  The maintenance operation server 100 includes a business management unit 101 and an NE information DB 102. In response to instructions from the terminal devices 111a, 111b,..., 111n, the business management unit 101 performs maintenance operation of NEs belonging to the A station, the B station, the C station,. The NE information DB 102 is a database in which state information indicating the state of the NEs of the A station, the B station, the C station,. For example, the connection relationship indicating which NE is connected according to the signal band, the operation state, the type of package (board) inserted in the NE shelf, and the version are stored.

  Each of the NEs communicates via an optical cable, and the communication line network underneath can communicate with other communication line networks via the NE. For example, although not shown, a communication line network below NEs 131a, 131b,..., 131n can communicate via NEs 131a, 131b,.

  The terminal devices 111a, 111b,..., 111n transmit information input by an operator who performs maintenance operation of the NE to the maintenance operation server 100. On the screens of the terminal devices 111a, 111b,..., 111n, a screen for the operator to perform maintenance operation of the NEs 131a, 131b,..., 131n is displayed. And transmitted to the maintenance operation server 100.

  In such a maintenance operation system, there is an operation of NE matching. The NE matching is an operation for checking whether or not the NE status information stored in the NE information DB 102 of the maintenance operation server 100 matches the NE status actually installed in the communication network. is there. The NE matching is performed by an operator when the state of the NE is changed or at regular intervals in order to operate the communication line network with high reliability. In the following, it is assumed that the operator performs NE alignment work from the terminal device 111a.

  FIG. 11 is a diagram showing an NE matching screen displayed on the terminal device. As shown in the figure, on the screen 141 of the terminal device 111a, a station list 142 that displays a list of stations that are maintained and operated by the maintenance operation server 100, a device list 143 that displays a list of NEs that each station has, NE matching A button 144 for starting the operation is displayed.

  The operator selects a station for maintenance operation from the station list 142. Next, the NE of the selected station is selected from the device list 143. Then, a button 144 for starting NE matching is pressed. In FIG. 11, the station A is selected in the station list 142, and the NE list of the station A is displayed in the device list 143. NE # 1 is selected.

  When the business management unit 101 of the maintenance operation server 100 accepts that the button 144 is pressed from the terminal device 111 a, the selected NE (selected on the screen 141) installed in the communication line network via the network 121 is selected. NE) status information is read. Further, the business management unit 101 reads the status information of the selected NE from the NE information DB 102. The business management unit 101 compares the state information of the installed NE with the state information read from the NE information DB 102. If the status information is different, the task management unit 101 updates the NE status information installed in the NE information DB 102. If the state information matches (a state that should be originally), the operator is notified through the terminal device 111a. The operator repeats the above operation and performs NE matching for all NEs.

By the way, if the operator checks the NE matching one by one, it takes a considerable time. Moreover, if work is concentrated, the load (usage rate) of the central processing unit of the maintenance operation server 100 increases. Therefore, there is an apparatus that reduces the load by giving priority to matching data, increasing the reference cycle interval of data with high priority, and extending the reference cycle interval of data with low priority (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-17680 (page 6, FIG. 2)

  However, there is a problem in that the load on the central processing unit that executes these processes increases when the NE matching process periodically executed and other maintenance operation processes overlap.

  The present invention has been made in view of these points, and an object thereof is to provide a maintenance operation program that reduces the load by executing NE matching in accordance with the usage rate of the central processing unit.

  In the present invention, in order to solve the above problem, in the maintenance operation program for maintaining and operating a plurality of network elements (NE) 9a, 9b,..., 9n as shown in FIG. Usage rate acquisition means 2 for acquiring the usage rate, and according to the usage rate, status information regarding the status of the network elements 9a, 9b,..., 9n from the network elements 9a, 9b,. State information acquisition means 3 to be acquired, storage state information acquisition means 4 to acquire state information relating to the state of the network elements 9a, 9b,..., 9n stored in advance from the storage device 8 according to the usage rate, state information acquisition means 3 is a state information comparison unit 5 for comparing the state information acquired by the storage state information acquisition unit 4 with the state information acquired by the storage state information acquisition unit 4. Correspondingly, the maintenance operation program for causing to function status information is status information acquisition unit 3 obtained in the storage device 8 as a matching unit 6, which stores are provided.

  According to such a maintenance operation program, according to the usage rate of the central processing unit 7, the state information of the network elements 9 a, 9 b,..., 9 n installed in the communication network and the storage device 8 are stored in advance. The network elements 9a, 9b,..., 9n are acquired and compared. Then, according to the comparison result, the storage device 8 stores the status information of the network elements 9a, 9b,..., 9n installed in the communication line network.

  According to the maintenance operation program of the present invention, when the usage rate of the central processing unit 7 is low, the status information of the network elements 9a, 9b,. The status information of the network elements 9a, 9b,..., 9n installed according to the comparison result is stored in the storage device 8 by acquiring and comparing the status information being stored. The load can be reduced.

  Hereinafter, the principle of the present invention will be described. FIG. 1 is a principle diagram illustrating the principle of the present invention. As shown in the figure, the computer 1 has a usage rate acquisition unit 2, a state information acquisition unit 3, a storage state information acquisition unit 4, a state information comparison unit 5, a matching unit 6, a central processing unit 7, and a storage unit 8. doing. The computer 1 is connected to NEs 9a, 9b,..., 9n installed in a communication network.

The usage rate acquisition unit 2 acquires the usage rate of the central processing unit 7. The central processing unit 7 executes an OS (Operating System) and application programs.
When the usage rate of the central processing unit 7 is below a certain value, the status information acquisition means 3 accesses the NEs 9a, 9b,..., 9n installed in the communication network and the statuses of the NEs 9a, 9b,. Get status information about. The status information is, for example, the connection relationship with which NE is connected depending on the signal band, the operation status, the type of package inserted in the NE shelf, and the version.

  The storage state information acquisition unit 4 acquires state information of NEs 9a, 9b,..., 9n stored in advance from the storage device 8 when the usage rate of the central processing unit 7 is equal to or less than a predetermined value. For example, the status information is stored in the storage device 8 when an NE is additionally installed in the communication line network.

The state information comparison unit 5 compares the state information acquired by the state information acquisition unit 3 with the state information acquired by the storage state information acquisition unit 4.
When the state information comparison unit 5 determines that the state information acquired by the state information acquisition unit 3 is different from the state information acquired by the storage state information acquisition unit 4, the matching unit 6 stores the state information in the storage device 8. The status information acquired by the acquisition means 3 is stored.

The operation of the principle diagram will be described below.
When the usage rate of the central processing unit 7 is below a certain value, the status information acquisition means 3 accesses the NEs 9a, 9b,..., 9n installed in the communication network and the statuses of the NEs 9a, 9b,. Get status information about.

The storage state information acquisition unit 4 acquires state information of NEs 9a, 9b,..., 9n stored in the storage device 8 when the usage rate of the central processing unit 7 is equal to or less than a predetermined value.
The state information comparison unit 5 compares the state information acquired by the state information acquisition unit 3 with the state information acquired by the storage state information acquisition unit 4.

  When the state information comparison unit 5 determines that the state information acquired by the state information acquisition unit 3 is different from the state information acquired by the storage state information acquisition unit 4, the matching unit 6 stores the state information in the storage device 8. The status information acquired by the acquisition means 3 is stored. That is, the status information of the storage device 8 is matched with the current status information of the network elements 9a, 9b,.

  As described above, when the usage rate of the central processing unit 7 is low, the state information of the installed network elements 9a, 9b,..., 9n and the state information stored in the storage device 8 are acquired and compared. To do. Then, the status information of the installed network elements 9a, 9b,..., 9n is stored in the storage device 8 according to the comparison result. Thereby, the load of the central processing unit 7 can be reduced.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 is a diagram showing a configuration example of the embodiment of the present invention. As shown in the figure, terminal devices 21a, 21b,..., 21n used by an operator are connected to the maintenance operation server 10. Further, NEs managed for each of stations A, B, C,... Are connected to the maintenance operation server 10 via a network 31 that is a LAN, for example. The station A has NEs 41a, 41b,..., 41n as shown (the NEs of the stations B, C,... Are not shown).

  The maintenance operation server 10 includes a business management unit 11, an NE information DB 12, an automatic matching unit 13, a matching priority list 14, an OS 15, and a CPU (Central Processing Unit) 10a. In response to an instruction from the terminal devices 21a, 21b,..., 21n, the business management unit 11 performs maintenance operation of NEs of the A station, the B station, the C station,. Further, the result of the maintenance operation is transmitted to the terminal devices 21a, 21b, ..., 21n. Further, the business management unit 11 accesses an NE installed in the communication network and reads state information indicating the state of the NE. The status information is, for example, the connection relationship with which NE is connected depending on the signal band, the operation status, the type of package inserted in the NE shelf, and the version. Further, the business management unit 11 reads NE status information stored in the NE information DB 12. In the NE information DB 12, for example, when the NE is added to the communication network or when the NE state is changed, the NE state information is stored by the operator from the terminal devices 21a, 21b,. Is done. Further, the task management unit 11 compares the state information read from the installed NE with the state information read from the NE information DB 12, and determines whether or not they match.

  The automatic matching unit 13 determines that the status information read from the installed NE and the status information read from the NE information DB 12 do not match, and the operator matches the NE matching. When it is instructed to perform automatically, NE matching processing is performed. Specifically, the automatic matching unit 13 updates the state information of the NE that does not match the state information in the NE information DB 12 to the state information of the installed NE.

  For example, when the NE is added to the communication network or the state of the NE is changed, the matching priority list 14 is created by the business management unit 11. The matching priority list 14 stores the NE name, whether automatic matching is possible, and the priority for performing NE matching. FIG. 3 is a data configuration example of the matching priority list. As shown in the figure, the matching priority list 14 has columns for NE name, automatic matching availability, and priority. In the NE name column, the name of the NE connected to the maintenance operation server 10 via the network 31 is stored. The NE name is determined by the operator. Information on whether or not NE matching is automatically performed is stored in the automatic matching availability column. Whether or not automatic alignment is possible is set by an operator, and indicates that automatic alignment is performed by OK, and that automatic alignment is not performed by NG. The priority column stores priorities in the order of NE matching. The priority includes a high priority with the highest priority, a low priority with the next highest priority, and no priority without performing NE matching. In the example of FIG. 3, the NE name NE # 1 indicates that automatic matching is performed when the automatic matching is OK. It also indicates that the priority is high priority.

  The OS 15 is basic software, and controls the resources of the maintenance operation server 10, specifically, the CPU 10a, memory, hard disk, and the like (details described later), and manages application operation control. Further, the OS 15 returns the current usage rate of the CPU 10 a by a system call from the business management unit 11.

  Each of the NEs communicates via an optical cable, and the communication line network underneath can communicate with other communication line networks via the NE. For example, although not shown, a communication line network below NEs 41a, 41b,..., 41n can communicate via the NEs 41a, 41b,.

Next, the hardware configuration of the maintenance operation server 10 having such a function will be described. FIG. 4 is a block diagram illustrating a hardware configuration of the maintenance operation server.
In the maintenance operation server 10 shown in the figure, the entire apparatus is controlled by the CPU 10a. A random access memory (RAM) 10b, a hard disk drive (HDD) 10c, a graphic processing device 10d, an input interface 10e, and a communication interface 10f are connected to the CPU 10a via a bus 10g.

  The RAM 10b temporarily stores at least part of an OS 15 program to be executed by the CPU 10a and an application program for maintaining and operating the NE. The RAM 10b stores various data necessary for processing by the CPU 10a. The HDD 10c stores an application program for maintaining and operating the OS 15 and NE.

  A monitor 10h is connected to the graphic processing device 10d. The graphic processing device 10d displays an image on the display screen of the monitor 10h in accordance with a command from the CPU 10a. A keyboard 10i and a mouse 10j are connected to the input interface 10e. The input interface 10e transmits a signal transmitted from the keyboard 10i or the mouse 10j to the CPU 10a via the bus 10g.

  The communication interface 10f is connected to the network 31. The communication interface 10f communicates with the NE via the network 31. Further, the communication interface 10f communicates with the terminal devices 21a, 21b, ..., 21n.

  With the hardware configuration as described above, the processing functions of the present embodiment can be realized. The terminal devices 21a, 21b,..., 21n have the same hardware configuration as that in FIG.

  Hereinafter, the operation of the maintenance operation server 10 will be described. First, the operation when a NE is newly added to the communication line network will be described. It is assumed that the operator uses the terminal device 21a to access the maintenance operation server 10 and register newly added NE status information. At this time, a screen asking whether the newly added NE can be automatically matched is displayed on the terminal device 21a.

  FIG. 5 is a diagram showing an automatic alignment permission / inhibition acceptance screen in the NE addition operation. As shown in the figure, a screen 51 is displayed on the terminal device 21a. On the screen 51, a text box 51a for registering the name of the newly added NE, check buttons 51b and 51c for accepting whether automatic alignment is possible, and information set on the screen 51 are transmitted to the maintenance operation server 10. A button 51d for displaying is displayed.

  When an NE is newly added to the communication line network, the operator inputs the name of the newly added NE in the text box 51a of the screen 51 from the terminal device 21a. Next, the operator uses the check buttons 51b and 51c to select whether or not to perform NE matching automatically. Then, when the operator presses the button 51d, the information set on the screen 51 is transmitted to the maintenance operation server 10. In the example of FIG. 5, the NE name NE # 1 is OK for automatic alignment (NE alignment is automatically performed).

  The business management unit 11 of the maintenance operation server 10 receives the NE name, information on whether automatic matching is possible, and status information of the NE transmitted from the terminal device 21a, and stores them in the NE information DB 12. In addition, the task management unit 11 adds information transmitted from the terminal device 21 a to the matching priority list 14. Specifically, the NE name input by the operator using the terminal device 21a is additionally written in the NE name column shown in FIG. Further, the automatic alignment availability input by the operator through the terminal device 21a is additionally written in the automatic alignment availability column. In the priority column, high priority is additionally written automatically (regardless of the operator's intention).

  Next, the operation when the NE is removed from the communication network will be described. When the NE is removed from the communication line network, the operator performs a deletion operation from the terminal device 21a. In response to the deletion request from the terminal device 21a, the business management unit 11 of the maintenance operation server 10 deletes the NE information requested for deletion from the NE information DB 12. In addition, the business management unit 11 deletes the NE information requested to be deleted from the consistent priority list 14.

  Next, the operation of the automatic alignment process will be described. The business management unit 11 acquires the current usage rate of the CPU 10a. If the usage rate of the CPU 10a is equal to or less than a certain value, the business management unit 11 determines a high priority NE among the NEs registered in the matching priority list 14. Next, the business management unit 11 accesses the NE installed in the communication line network corresponding to the NE determined from the matching priority list 14 and reads the status information of the NE. Further, the task management unit 11 reads NE status information stored in the NE information DB 12 corresponding to the NE determined from the matching priority list 14. Then, the task management unit 11 compares the state information read from the installed NE with the state information read from the NE information DB 12. If the information on the installed NE does not match the information on the NE stored in the NE information DB 12, the business management unit 11 displays the fact on the terminal device 21a. Notify the operator. Further, the task management unit 11 refers to the matching priority list 14 and determines whether automatic matching is permitted (OK). When the business management unit 11 determines that automatic matching is permitted, automatic matching is performed by the automatic matching unit 13.

  When the task management unit 11 determines that the status information read from the installed NE matches the status information read from the NE information DB 12, the automatic matching unit 13 determines the NE status of the NE information DB 12. The information is updated to the state information acquired from the installed NE. When the automatic matching by the automatic matching unit 13 is completed, the business management unit 11 displays a message to that effect on the terminal device 21a and notifies the operator. The task management unit 11 updates the priority column of the matching priority list 14 to no priority.

  FIG. 6 shows an example of the data structure of a consistent priority list in which high priority is updated to no priority. For example, assume that the NE with the NE name NE # 1 in the matching priority list 14 shown in FIG. 3 is automatically matched. In this case, as shown in FIG. 6, the priority of the NE name NE # 1 in the matching priority list 14 is updated to no priority.

  When the high priority NE consistency check (comparison between the state of the installed NE and the state stored in the NE information DB 12) is completed, the business management unit 11 selects the low priority NE from the consistency priority list 14. Find out. Then, the business management unit 11 compares the state information of the installed NE with the state information of the NE stored in the NE information DB 12 in the low priority NE as in the case of the high priority. The task management unit 11 displays the comparison result on the terminal device 21a and notifies the operator, and determines whether the automatic matching in the matching priority list 14 is OK or NG. If it is OK, the automatic matching unit 13 updates the NE information DB 12 by performing automatic matching, and the job management unit 11 notifies the operator that the automatic matching has been completed via the terminal device 21a. Then, the task management unit 11 updates the priority column of the matching priority list 14 to no priority.

  FIG. 7 shows an example of the data structure of a consistent priority list in which low priority is updated to no priority. For example, assume that the NE with the NE name NE # 3 in the matching priority list 14 shown in FIG. 6 is automatically matched. In this case, as shown in FIG. 7, the NE priority of the NE name NE # 3 in the matching priority list 14 is updated to no priority. Note that the NE with the NE name NE # 2 has NG as to whether or not automatic alignment is possible, and therefore, the priority is given no priority when the operator performs alignment processing.

  The business management unit 11 collectively replaces the priority with a low priority when all of the priority fields in the consistent priority list 14 are unprioritized. FIG. 8 shows an example of the data structure of a matching priority list that is collectively replaced with low priority. For example, it is assumed that the NE of the NE name NE # 2 in the matching priority list 14 shown in FIG. 7 is matched, and that another low priority NE is also automatically matched or matched by the operator. In this case, as shown in FIG. 8, the matching priority list 14 is all updated to the low priority.

  Here, the acquisition of the CPU usage rate will be described. The business management unit 11 makes a system call to the OS 15. The OS 15 receives the system call from the business management unit 11 and acquires the usage rate of the CPU 10a.

  The usage rate of the CPU 10a is an instantaneous value when a system call is made. Therefore, the task management unit 11 obtains the usage rate of the CPU 10a at intervals of n seconds, and determines that the load is low when it is equal to or less than a certain value continuously m times. Tuning n and m makes it possible to adjust the schedule for executing the matching process.

  Hereinafter, the operation of the automatic alignment process will be described with reference to a flowchart. FIG. 9 is a flowchart showing the operation of the automatic matching process. The maintenance operation server 10 executes the automatic matching process according to the following steps.

[Step S1] The business management unit 11 of the maintenance operation server 10 makes a system call to the OS 15 at a predetermined cycle, and acquires the usage rate of the CPU 10a.
[Step S <b> 2] The business management unit 11 determines whether or not the usage rate is equal to or lower than a predetermined value for a predetermined number of times. If the predetermined number of times continues, the process proceeds to step S3. If the predetermined number of times is not continued, the process proceeds to step S1.

  [Step S <b> 3] The business management unit 11 refers to the matching priority list 14 to determine an NE with a high priority (if there is no higher priority NE, an NE with the next highest priority is determined).

  [Step S4] The business management unit 11 acquires NE status information corresponding to the calculated NE from the NEs installed in the communication network. Also, status information corresponding to the NE determined from the NE information DB 12 is acquired.

  [Step S5] The business management unit 11 compares the state information acquired from the installed NE with the state information acquired from the NE information DB 12. If the state information does not match, the process proceeds to step S6. If they match, the process proceeds to step S10.

[Step S6] The task management unit 11 transmits the comparison result to the terminal device 21a and notifies the operator.
[Step S <b> 7] The task management unit 11 refers to the matching priority list 14 and determines whether automatic matching is OK or NG. If OK, the process proceeds to step S8. If it is NG, an alignment process is performed by the operator and the process proceeds to step S10.

[Step S8] The automatic matching unit 13 performs automatic matching processing for updating the NE information in the NE information DB 12 to the state information read from the installed NE.
[Step S9] The task management unit 11 transmits the matching result to the terminal device 21a and notifies the operator.

[Step S10] The task management unit 11 updates the priority of the determined NE matching priority list 14 to no priority.
[Step S <b> 11] The task management unit 11 determines whether all the priorities in the matching priority list 14 have no priority. If no priority is given, the process proceeds to step S12. If no priority is given, the process proceeds to step S1.

[Step S12] The task management unit 11 updates all the priorities in the matching priority list 14 to low priority.
Next, a case where the NE state is changed will be described. For example, when the NE state is changed by changing the NE connection relationship or by replacing the package, the operator accesses the maintenance operation server 10 from the terminal device 21a and updates the NE information whose state has been changed. To do.

  The business management unit 11 of the maintenance operation server 10 updates the information in the NE information DB 12 to the NE changed status information transmitted from the terminal device 21a. In addition, the business management unit 11 gives high priority to the NE priority column in which the matching priority list 14 has been changed. Therefore, when the automatic matching process occurs next, the NE whose state has been changed becomes the NE matching target.

  Next, a case where communication with the NE is disconnected and restored will be described. When the business management unit 11 of the maintenance operation server 10 detects from the NE that the communication with the NE has been disconnected and then recovered, the priority of the matching priority list 14 of the corresponding NE is updated to high priority. Therefore, the NE whose communication has been disconnected is restored and then becomes a target for NE matching.

As described above, since the alignment process is performed when the usage rate of the CPU 10a is below a certain level, the load on the CPU 10a can be reduced.
In addition, since the matching process is performed when the load on the CPU 10a is small, the influence on other maintenance operations is reduced.

  Further, by performing the automatic alignment and performing the NE alignment when the usage rate of the CPU 10a is below a certain level, the operator does not need to be aware of the NE alignment work, and the work is simplified.

  Further, when the state information of the NE changes or when the communication is disconnected and restored, these NEs are subjected to NE matching by setting the priority to high priority. Thereby, it is possible to realize a highly reliable communication with a low load.
