Method for automatically synchronizing a database of the network management system

The present invention relates to a method for automatically synchronizing a database of a network management system. In particular, the present invention relates to a method of automatically synchronizing information of an optical transmission apparatus with information of a database stored in a network management system to search for inconsistent information and automatically apply the information according to the search result. The present invention relates to a method for automatically synchronizing a database of a network management system by updating information to synchronize a database of a network management system, thereby preventing a mismatch between information of an optical transmission apparatus and information of a database of a network management system.

In general, as the information society develops, as the role of communication network plays an increasing role in society as a whole, the centralization and automation of communication network operation management has emerged as an essential component of communication network. Therefore, in consideration of the importance of network operation management, ITU-T also sets the management system element as an automation / centralization concept for the communication network, for example, the network management system as an essential component of the communication network.

Such a network management system (hereinafter referred to as a network management system) is an operation system that normally operates a communication network in the form of automation / centralization, and is characterized by various types of communication networks, for example, an SDH optical transmission device, a SONET, or a plurality of SDHs. Connected by the equipment and the data communication network, it collects and accumulates various kinds of information from the SDH, and basically provides a function of processing and processing various communication network management information from these information. Accordingly, such a network management system normally performs a function of storing, for example, event information, which is output from an online communication module, for example, event information, etc. output from a device such as SDH, in a table of a database by executing an appropriate process.

Then, referring to the conventional optical transmission device network management system as described above with reference to FIG. 1, a network management system system to which the present invention is applied includes a client computer 1 for receiving and processing a control command from a user, and the client computer 1 And a network management system server (2) for processing the target command according to the control command signal inputted from the network), and the target command signal to the optical transmission device according to the control command of the network management system server (2). NE-MANAGER (hereinafter referred to as NE manager) that transmits the response information transmitted from the network management system server 2, and information input from the NE manager 3 is stored in a database (hereinafter referred to as DB). EVENT-SERVER (hereinafter referred to as EVT server) for transmitting the event information to the client computer 1, and a command signal transmitted from the EVT server 4 or the client computer 1 to the network management system. DB- which updates the information of DB 5 according to the response signal transmitted from the network management system server 2 and transmits the response signal to the client computer 1 according to the command request target. It consists of SYNCHOR (hereinafter referred to as DB sinker).

Here, the network management system server 2 receives a command from the DB sinker 6 and delivers the command to the NE manager 3, and transfers the information received from the NE manager 3 to the client computer 1 according to the command request target. ) Or to the DB sinker 6. When the transmitted signal is an event, the NE manager 3 performs a function of transmitting to the EVT server 4.

On the other hand, referring to Figure 2 of the synchronization method applied to the network management system as described above, the network management system of the optical transmission device proceeds from the initial state (S1) to the DB information processing step (S2) of the currently connected optical transmission device (7). Event information, for example, equipment configuration information or failure information, is processed. Then, after the DB information processing step (S2) to proceed to the user query input step (S3) to determine whether the inquiry command is input from the current user. At this time, if the inquiry command is not input from the user as a result of the determination during the user inquiry input step S3, the process returns to the previous step S2 and repeats the loop. In addition, if the inquiry command is not input from the user as a result of the determination during the user inquiry input step (S3), the process proceeds to the user inquiry command processing step (S4) and transmits the request signal according to the inquiry command of the currently input user to the optical transmission device. After inputting, process the response signal according to the inquiry and update the result in DB.

In addition, after the user query command processing step (S4), and proceeds to the DB synchronization command determination step (S5) to determine whether the DB synchronization command is input from the user. At this time, if the DB synchronization command is not input from the user as a result of the determination during the DB synchronization command determination step (S5), the process proceeds to the DB information processing step (S2) and repeats the loop.

On the other hand, if the DB synchronization command is input from the user as a result of the determination during the DB synchronization command determination step (S5), proceeds to the DB synchronization execution step (S6) and the network management system requests the synchronization information to the optical transmission device, and then the response Synchronize the information of the DB by comparing the information with the information currently stored in the DB.

That is, the client computer 1 generates a command to perform DB synchronization by the DB synchronization item created according to the user's synchronization request command, requests the network management system server 2, and stores the command in the synchronization command queue. In addition, the command is stored in the timer for a timeout procedure. At this time, the network management system server 2 requests a general command to the NE manager 3 and then requests a DB synchronization command to the NE manager 3. The network management system server 2 transmits a DB synchronization command to the NE manager 3, and accordingly the NE manager 3 sends this synchronization command signal to the optical transmission device 7 according to the input DB synchronization command. send. Then, the optical transmission device 7 transmits a response signal to the DB synchronization command of the NE manager 3, where the NE manager 3 inputs the input DB synchronization information to the network management system server 2. Let's do it. Then, the network management system server 2 transmits the input DB synchronization information to the DB sinker 6, and accordingly, the DB sinker 6 uses the input synchronization information to transmit the information of the DB 5. The DB 5 is synchronized by updating the ITEM index of the DB by updating the corresponding ITEM index included in the information.

However, the database synchronization method of the conventional network management system as described above is a DB of the network management system because the network management system is a passive information provision form in which the network management system sends a request signal to the optical transmission device to query the information only by a user command. There was a flaw in the effectiveness of management.

In addition, the database synchronization method of the conventional network management system as described above does not have a system for automatically comparing the information of the optical transmission device and the DB information of the network management system, so that external special operations in case of inconsistency of the DB information are prevented. If the event occurs because the information of the optical device is continuously changed and the information of the optical device is not synchronized, even if the DB is manually synchronized, it is determined whether the synchronized information has been synchronized to the DB as appropriate information due to the time difference with the new event. There was a problem that can not.

Accordingly, the present invention has been invented to solve the above-mentioned problems, and periodically compares the information of the optical transmission device with the information of the database stored in the network management system to search for mismatched information and automatically applies the search results accordingly. By updating the information and synchronizing the database of the network management system, the information of the optical transmission device and the information of the database of the network management system can be prevented from being inconsistent, thereby reducing the processing error of the network management system. Its purpose is to provide an automatic database synchronization method.

Another object of the present invention is to automatically synchronize the information of the database of the network management system with the information of the optical transmission device, so that the efficiency of information management of the database stored in the network management system is also significantly increased database automatic synchronization method To provide.

The present invention for achieving the above object is a manual DB synchronization execution step of executing a manual DB synchronization mode according to the DB synchronization signal input from the user, and after the DB synchronization execution step of the information of the optical transmission device and the network management system DB DB information mismatch automatic search process that automatically detects whether the information is inconsistent, and if the information change of the optical transmission device is confirmed by this DB information mismatch automatic search process, the index of the event information of the optical transmission device and the DB The missing information checking step of comparing the index of the stored information to check whether there is missing information between them, and executing the automatic DB synchronization procedure to execute the automatic DB synchronization procedure when the missing information is confirmed by the missing information checking step. It provides a database automatic synchronization method of the network management system comprising a step.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring again to the network management system system to which the present invention is applied with reference to FIG. 1, the client computer 1 that receives and processes a control command from a user and according to the control command signal input from the client computer 1. The network management system server 2 for processing the target command and the target command signal are transmitted to the optical transmission device according to the control command of the network management system server 2 and the response information transmitted from the optical transmission device is transmitted to the network management system. An NE manager 3 for transmitting to the server 2, and an EVT server for storing information input from the NE manager 3 in a database (hereinafter referred to as DB) and transmitting the corresponding event information to the client computer 1 ( 4) and the command signal transmitted from the EVT server 4 or the client computer 1 to the network management system server 2, and then according to the response signal transmitted from the network management system server 2 according to the DB ( It consists of the DB sinker 6 which updates the information of 5) and transmits a response signal to the client computer 1 according to the command request object.

Here, the network management system server 2 receives a command from the DB sinker 6 and delivers the command to the NE manager 3, and transfers the information received from the NE manager 3 to the client computer 1 according to the command request target. ) Or to the DB sinker 6. When the transmitted signal is an event, the NE manager 3 performs a function of transmitting to the EVT server 4.

Here, the DB synchronization information is to synchronize the configuration information (configuration) of the optical transmission device 7, the shelf setting state, the slot setting plaque, the alert state, the port setting status, the cross-connection state, the TSA state, It includes CLOCK status, switching status, optical link connection status, loopback status and path switching status.

The following describes the method of the present invention applied to such a system.

The method of the present invention proceeds to the manual mode determination step S2 in the initial state S1 as shown in FIG. 3 to determine whether a specific control command has been input from the current user. When a specific control command is input from the current user as a result of the determination in the manual mode determination step (S2), the process proceeds to the manual mode execution step (S3) and executes DB synchronization according to the manual mode.

That is, when a DB synchronization command signal is input from the user through the client computer 1, the client computer 1 requests the DB sink item and the shelf of the optical transmission device requesting DB synchronization to the DB sinker 6 (REQUEST). do. At this time, the DB sinker 6 returns a FAIL signal to the client computer 1 if DB synchronization is currently being executed. When the DB sinker 6 generates an event during DB synchronization of the optical transmission device 7, the DB sinker 6 requests an event-pending process from the EVT server 4 for the event. Therefore, this EVT server 4 executes the PENDING process for the event of the optical transmission device 7 which will occur later.

The client computer 1 generates a command to perform DB synchronization according to the DB synchronization item, requests the network server to the network management system server 2, stores the command in the synchronization command queue, and stores a timeout procedure. In order to save the command to the timer. At this time, the network management system server 2 requests a general command to the NE manager 3 and then requests a DB synchronization command to the NE manager 3. The network management system server 2 transmits a DB synchronization command to the NE manager 3, and accordingly the NE manager 3 sends this synchronization command signal to the optical transmission device 7 according to the input DB synchronization command. send. Then, the optical transmission device 7 transmits a response signal to the DB synchronization command of the NE manager 3, where the NE manager 3 inputs the input DB synchronization information to the network management system server 2. Let's do it. Then, the network management system server 2 transmits the input DB synchronization information to the DB sinker 6, and accordingly, the DB sinker 6 uses the input synchronization information to transmit the information of the DB 5. Update and update the ITEM index of the DB with the corresponding ITEM index included in the information. At this time, the DB sinker 6 deletes the information corresponding to the received command from the synchronization command queue and timer, and checks whether the DB synchronization is completed through the synchronization out command queue, and repeats the above process if the DB synchronization is not completed. To perform. However, the DB sinker 6 transmits the moving room to the EVT server 4 when the DB synchronization is completed. Accordingly, the EVT server 4 processes the event that has been previously pending, then transmits a response signal indicating that the DB synchronization is completed to the client computer 1 that requested the DB synchronization, and then ends the manual mode operation.

On the other hand, if a specific control command is input from the current user as a result of the determination in the manual mode determination step (S2), the process proceeds to the DB synchronization automatic execution step (S3) to receive information from the optical transmission device for DB synchronization according to the automatic mode. Compare with DB information. After the DB synchronization automatic execution step S3, the synchronization information determination step S4 is performed to determine whether the information of the optical transmission device and the information of the network management system DB are inconsistent.

That is, the EVT server 4 compares the information of the optical transmission device with the ITEM INDEXGROUP signal received from the optical transmission device and the ITEM INDEX GROUP signal included in the event information in the DB. Determine whether there is a mismatch of information in the network management system DB.

At this time, if it is determined during the synchronization information determination step (S4), if the information of the optical transmission device and the information of the network management system DB is identical to the end step. However, if it is determined during the synchronization information determination step (S4) that the information of the optical transmission device and the information of the network management system DB does not match, proceed to the synchronization item request step (S5) to request the inconsistent synchronization items of the DB to the DB sinker. do. After the synchronization item request step (S5), the process proceeds to the DB synchronization determination step (S6) to determine whether the current DB synchronization is running. At this time, if it is determined during the DB synchronization determining step (S6), if the current DB synchronization is in progress proceeds to the event occurrence determination step (S8) to determine whether an event has occurred in the optical transmission device that is currently DB synchronization. If the event does not occur in the optical transmission device currently synchronizing the DB as a result of the determination in the event occurrence determining step (S8), the process proceeds to the end step. However, when an event occurs in the optical transmission device currently synchronizing the DB as a result of the determination in the event occurrence determining step (S8), the process proceeds to the event pending step (S9) to process the event generated in the optical transmission device currently synchronizing the DB.

That is, the EVT server 4 requests the DB sinker 6 to transmit the mismatched DB synchronization item when the DB is mismatched in the process. At this time, the DB sinker 6 does not perform DB synchronization if DB synchronization is currently being performed. However, this DB sinker 6 requests event PENDING processing to the EVT server 4 if there is an event occurring during DB synchronization of the optical transmission apparatus currently performing DB synchronization. Then, the EVT server 4 processes the event of the optical transmission device 7 to be generated later.

As a result of the determination during the DB synchronization determination step (S6), if the current DB synchronization is not in progress, proceeds to the DB synchronization operation execution step (S10) to execute the DB synchronization operation by creating a DB synchronization command according to the DB synchronization items.

That is, the client computer 1 creates a command to perform database synchronization according to the DB synchronization item and stores the command in the synchronization command queue. The client computer 1 then requests the network management system server 2 for the command stored in the synchronization command queue, stores the command in the synchronization command queue, and stores the command in a timer for a timeout procedure. At this time, the network management system server 2 requests a general command to the NE manager 3 and then requests a DB synchronization command to the NE manager 3. The network management system server 2 transmits a DB synchronization command to the NE manager 3, and accordingly the NE manager 3 sends this synchronization command signal to the optical transmission device 7 according to the input DB synchronization command. send. Then, the optical transmission device 7 transmits a response signal to the DB synchronization command of the NE manager 3, where the NE manager 3 inputs the input DB synchronization information to the network management system server 2. Let's do it. Then, the network management system server 2 transmits the input DB synchronization information to the DB sinker 6.

On the other hand, after the DB synchronization task execution step (S10) proceeds to the DB synchronization information update step (S11) to update the DB information of the network management system using the information of the optical transmission device.

That is, the DB sinker 6 updates the information of the DB 5 using the synchronization information received by the above process, and updates the ITEM index of the DB with the corresponding ITEM index included in the information. At this time, the DB sinker 6 deletes the information corresponding to the received command from the synchronization command queue and timer, and checks whether the DB synchronization is completed through the synchronization out command queue, and repeats the above process if the DB synchronization is not completed. To perform.

However, the DB sinker 6 transmits the moving room to the EVT server 4 when the DB synchronization is completed. Therefore, the EVT server 4 processes the previously-pending event and then transmits a response signal indicating that the DB synchronization is completed to the client computer 1 requesting the DB synchronization, and then terminates the synchronization operation of the DB.

On the other hand, after the event pending step (S9) proceeds to the DB synchronization failure message transmission step (S11) to send an error message according to the DB synchronization failure to the client computer requesting the DB synchronization command.

That is, when the DB synchronization process requested by another client computer is already performed as in the above process, an ERROR MESSAGE is returned to the corresponding client computer 1 requesting the DB synchronization. In addition, when the DB sinker 6 fails to transmit data from the optical transmission device 7, the DB sinker 6 responds to the client computer 1 with the cause of failure and terminates the DB synchronization procedure.

At this time, when the DB sinker 6 ends abnormally, the PENDING release indication is processed by the EVT server 4, and when there is no response from the network management system server 2 during DB synchronization, the DB sinker 6 times out. Process and respond to the client computer 1.

In other words, DB synchronization by user's request can be performed on a per-item basis, and these items are selected on the client computer 1 and sent to the DB sinker 6 so that the DB sinker 6 only manages the network management system server for the selected commands. REQUEST the synchronization command with (2).

At this time, the command transmitted to the network management system server 2 is REQUEST as multiple commands, and the REQUEST command is transmitted from the network management system server 2 to the NE manager 3.

At the same time as the above process, the DB sinker 6 updates the corresponding data in the DB 5 when a response signal is received from the network management system server 2 and waits until all commands arrive at the network management system server 2. After all the commands arrive, RESPONSE that all DB synchronization has been completed to the client computer (1).

At this time, if there is no response from the network management system server 2 for a predetermined time, the DB sinker 6 transmits that the DB synchronization failed to the client computer 1 through the TimeOut function of the program.

In this case, when an event is delivered due to a change of information of the device 7 being synchronized with DB during the process of starting the DB synchronization, the EVT server 4 processes the event and processes the event after DB synchronization is completed. do. Therefore, it is possible to prevent database synchronization inconsistency that may occur during database synchronization through the EVET PENDING function of the EVT server 4 in advance.

In order to perform the above functions, the PENDING START operation to PENDING the event of the device to the EVT server 4 and the PENDING END operation to process the PENDING event again when the database synchronization is completed. do.

Meanwhile, in order to automatically synchronize the database, the procedure and data for checking whether the information of the optical transmission device and the information of the database of the network management system are the same are necessary, and the optical transmission device 7 changes the corresponding information. If so, increase the specific ITEM of that information.

If an alarm occurs, the optical transmission device 7 increases the information ITEM alarm index and forwards the event including the alarm index to the alarm event. Then, the EVT server 4 stores the alarm index of the device in the database. Compare the alarm index of the ITEM INDEX GROUP with the alarm index to see if there is a missing gap between the previously occurring alarm event and the currently occurring alarm event.

At this time, if there is no missing information as determined by the EVT server 4, only the alarm index is updated and a normal processing procedure is entered. If there is missing information, the EVT server 4 automatically alerts the DB sinker 6 about the alarm. Start the DB synchronization procedure.

In addition, the optical transmission device 7 periodically transmits the ITEM INDEX GROUP stored in the device to the EVT server 4 as an event. The EVT server 4 compares the indexes of the device 7 with the indexes of the network management system DB and performs a database synchronization command procedure only for the corresponding item when a mismatch occurs.

Here, the method of the present invention has been described with reference to only the network management system of the SDH device, but the method of the present invention is applied to both the network management system and the NMS of the SONET and SDH series over-transmission devices.

As described above, the present invention periodically compares the information of the optical transmission apparatus with the information of the database stored in the network management system, searches for inconsistent information, and automatically updates the information according to the search result, thereby providing data of the network management system. By synchronizing the base, it is possible to prevent inconsistency between the information of the optical transmission device and the information of the database of the network management system, thereby reducing the processing error of the network management system.

Further, according to the present invention, since the information of the database of the network management system is automatically synchronized with the information of the optical transmission device, the efficiency of information management of the database stored in the network management system is also significantly increased.
