Description

Network management system and its control method {EMS and controlling method therefore}

The present invention relates to a network management system and a control method thereof. In particular, when a plurality of commands are distributed to a EMS server at the same time by distributing user request information by creating a command to reduce a plurality of request times in a EMS process through a queue. By distributing these commands, the present invention relates to a network management system capable of preventing overload of a network and a device connected to an optical transmission system and a control method thereof.

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.

The element management system (EMS) as described above typically includes various types of communication networks, such as a client (CLIENT), an SDH optical transmission device, a SONET, or a plurality of SDH devices and are connected by a data communication network. It basically collects and accumulates various kinds of information and processes and processes various communication network management information from these information. Therefore, such EMS normally performs a function of storing, for example, event information and the like, output from a plurality of optical transmission devices such as SDH delivered from an online communication module, in a table of a database by executing an appropriate process.

Then, referring to FIG. 1, the network management apparatus of the conventional optical transmission system as described above, includes a plurality of client computers 1A-N and a plurality of client computers 1A-N that receive and process a control command from a user. The network management system server 2 processes the target command according to the control command signal inputted from any one of the plurality of optical transmission apparatuses 7A- and the target command signal according to the control command of the network management system server 2. N) and a NE manager (hereinafter referred to as NE manager) for transmitting to the network management system server 2 the response information transmitted from the plurality of optical transmission devices 7A-N to N), and the NE manager 3 An EVENT server (hereinafter referred to as an EVT server) that stores information input from the database in a database (hereinafter referred to as DB) and transmits the corresponding event information to any of the client computers 1A-N, and the EVT server 4 Or client computer (1A- N) transmits the command signal transmitted from N) to the network management system server 2, and then updates the information of the DB 5 according to the response signal transmitted from the network management system server 2, and the client computer according to the command request target. And a DB-sinker 6 (hereinafter referred to as a DB sinker) that transmits a response signal to 1A-N.

Here, the network management system server 2 receives a command from the DB sinker 6 and delivers it to the NE manager 3, and transmits the information received from the NE manager 3 to the client computer 1A according to the command request target. -N) or transmits 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 the operation of the network management system as described above, when any one of the plurality of client computers (1A-N) the user sets a command, for example, the synchronization command of the optical transmission device 7A synchronization command of the user Is received by the DB sinker 6. Then, the DB sinker 6 creates 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. The command is stored in the timer for the 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 the synchronization command signal to the corresponding optical transmission device 7A according to the input DB synchronization command. Send it. Then, the optical transmission device 7A 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, since the network management method of the conventional optical transmission system as described above can handle only a user command input from one client computer 1A-N, when a plurality of users simultaneously request processing commands, The disadvantage is that the process can overload the network or device.

In addition, the conventional network management system as described above can not process any reservation command or a priority command because the processing process is performed in the order of the time when the user gives the command, thereby significantly reducing the EMS processing efficiency. It caused a problem.

Accordingly, the present invention has been invented to solve the conventional problems as described above, by creating a command to reduce a plurality of request time in the EMS process through the queue to distribute the user request information and at the same time a plurality of commands to the EMS server It is an object of the present invention to provide a data processing method of a network management system capable of preventing overload of a network and a device connected to an optical transmission system by distributing these commands when they are delivered.

Another object of the present invention is to assign a priority to the processing using the request time for all the input commands and to process the necessary commands according to the priority given by the data of the network management system to significantly improve the processing efficiency of the EMS accordingly To provide a treatment method.

The present invention for achieving the above object is a network management system including a DB-Thinker, EVT-server, EMS server and NE manager connected to a plurality of clients and management devices, the EMS server is input from a plurality of clients A command request receiving (cmdRequestReceiver) interface module that receives the received command and interfaces with a corresponding command signal, a command request memory (RequestCmdQueue) register for storing and processing user command information input from the command request receiving interface module, and the command A command dispatch (CmdDispatcher) module for distributing a plurality of commands having elapsed time in the request memory register according to priority and transmitting response request information for the command to the corresponding device; Search the device via NE manager according to the command information input from the module. The command response module (cmdResponseReceiver) interface module for processing the response signal, and the request time information inputted from the command sending module and the command response receiving interface module is stored and the reservation command function and time-out function are used by using the end of the request time. Provides a network management system that includes a command response memory (ResponseCmdQueue) register.

Another feature of the present invention is a multiple information input step of classifying and storing a plurality of user information inputted from a plurality of clients by a command request receiving interface module in a command request memory register in a network management system, and a minimum time set after the multiple information input step. The instruction sending module that executes the program once every time searches the contents of the instruction request memory register once at least every set time, and decreases the request time of each instruction by one second each time the set time elapses. The command sending processing step of transferring to the corresponding device according to the order and storing the result in the command response memory register, and the response to the device processing command pre-stored in the command response memory register by the command response receiving interface module after the command sending processing step are applicable.

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

The network management system to which the present invention is applied has the same structure as that of the network management system shown in FIG. 1, wherein any one of the DB-sinker 6, the EVT-server 4, and the plurality of client computers 1A-N is provided. EMS server 2 for processing the target command according to the control command signal input from the network, and the target command signal to the plurality of optical transmission devices 7A-N according to the control command of the network management system server 2. And an NE manager 3 for transmitting the response information transmitted from the plurality of optical transmission devices 7A-N to the network management system server 2.

In addition, the EMS server 2 of the present invention applied to the network management system as described above receives a command input from a plurality of client computers 1A-N as shown in FIG. A command request for storing and processing the user's command information inputted from the request receiving interface module 8 and the command request receiving interface module 8, for example, device name, command information, requestID, invokeID, request time, and the like. A command sending module 10 for distributing a memory register 9 and a plurality of commands whose demand time expires in the command request memory register 9 according to priority and transmitting response request information for the command to the corresponding device. And the corresponding device 7A-N via the NE manager 3 according to the command information input from the command sending module 10 to process the response signal. It stores the request time information input from the response receiving interface module 11, the command sending module 10 and the command response receiving interface module 11, and uses the end of the request time to execute the reservation command function and the timeout function. The command response memory register 12 to be executed and the EMS server 2 periodically executes the performance monitoring cumulative inquiry command, which is a command for periodically inquiring the information of the transmission device 7A-N and storing it in the DB 5. It includes a cycle command module 13 for making a corresponding command according to the time of the EMS server 2 to store in the command request memory register (9).

Here, the requestID stored in the command request memory register 9 is an ID for identifying a command, and InvokeID is information for identifying a user who issued the command, and when a response signal is received from a corresponding device later, the command response is transmitted to the corresponding client. Used to The request time is data indicating the last execution time by counting the current command from the current time, and the unit is seconds.

In addition, the command sending module 10 adjusts the priority so that the user's command is executed first rather than the command of the periodic command module 13 by searching for invokeID when there are two or more commands whose request time expires. In this case, the order execution priority is the request time. If the request time is the same, the user's command is given priority. If the request time is the same as the user command, the instruction inserted into the command request memory register 9 is first inserted. First of all, In addition, the command sending module 10 requests only one command at a time and performs distributed processing of the command.

Herein, if the command response memory register 12 has a command to be executed after 1 hour, for example, the request time of the command response memory register 12 is 3600 (60 * 60), which is down counted by 1 second. The 3600 is reduced to 0 seconds after 1 hour and terminates. Therefore, this command response memory register 12 transfers the reserved command to the corresponding devices 7A-N when the request time expires.

Next, the method of the present invention applied to the network management system as described above will be described.

As shown in FIG. 2, the network management system of the present invention mainly uses a timer function using a queue, that is, the command request memory register 9 and the command response memory register 12 are used. Each has data called request time. In this case, the request time is information indicating when the command should be performed for each command.

Therefore, the command sending module 10 and the command response receiving interface module 11 periodically query the command request memory register 9 and the command response memory register 12 to reduce the request time by one second. When the request time expires, the command is processed according to the process.

That is, the present invention proceeds to the multiple information input step (S2) in the initial state (S1) as shown in Figure 3, the command request receiving interface module sends a plurality of user information input from the plurality of clients to the command request memory register Sort and save.

After the majority information input step S2, the instruction sending module for executing a program at least once every second is performed by executing the instruction sending processing step S3 and searching the contents of the instruction request memory register at least once every second. The request time is reduced by 1 second for every 1 second, and the command whose request time expires is transferred to the corresponding device according to the processing priority and stored in the command response memory register.

In addition, after the command originating processing step S3, the command non-response result transmission step S4 is performed so that a response to the device processing command previously stored in the command response memory register by the command response receiving interface module does not reach within a predetermined time from the corresponding device. If not, change the request time to timeout and report this to the client.

However, after the command no response result transmission step S4, the command response processing step S5 is performed, and when the command response receiving interface module receives a response from the device requesting the response, the corresponding client is searched for the corresponding result. Send to client

Here, when two or more commands whose request time is stored in the command request memory register have expired are searched during the command origination processing step S3, the command originating interface module preferentially assigns a command whose invokId is not a periodic command to the corresponding device. To pass. At this time, if all of the above commands invokeId is not a periodic command (periodicCommand), the first command stored in the command request memory register is transmitted to the device. Therefore, the command origination processing step S3 performs a priority processing step of performing a priority order of the commands in the order of requestTime> invikeId> insert.

In the command response processing step (S5), if the invokeId of the command returned from the corresponding device is a periodic command, the periodic command module requests the command. Therefore, the information is stored in the command response memory register after storing the information in the database. Delete it.

In other words, in the method of the present invention, when a plurality of client computers 1A-N simultaneously transmit a command to the command request receiving interface module 8, the command request receiving interface module 8 sends the command request memory to the command request memory. All of them are stored in the register (9).

Here, the stored information stores general command information, request time for executing the command, information such as invokeid for identifying the command of the client, and requestId for assigning the ID of the command. In particular, the RequestID is transmitted to the corresponding device 7A-N and may be referred to as a command tag.

On the other hand, when the information of the plurality of client computers 1A-N is stored in the command request memory register 9, the command originating module 10 searches in the command request memory register 9 at least once every second for each command. Every 1 second past the required time, 1 second is reduced. At this time, if the command of which the request time expires is searched, the command is extracted from the command request memory register (9) and sent to the corresponding device (7A-N) via the corresponding NE manager (3). It is stored in the register 12.

Then, when the device processing command is stored in the command response memory register 12 as described above, the command response receiving interface module 11 does not receive the processing response to the command within the predetermined time from the device 7A-N. The request time is changed to timeout and stored in the command response memory register 12 in order to convey to the client (user) requesting the command that the command has not arrived for a certain time.

For example, assuming that the request time is set to 30, if there is no response for 30 seconds in the device 7A-N, the command response receiving interface module 11 may time out the corresponding client computer 1A-N. Report as.

At this time, if two or more commands whose required time expires are searched in the command request memory register 9, the command sending module 10 preferentially transmits a command whose invokId is not a periodic command to the device. If invokeId is not a periodic command in all of the above processes, the command first stored in the command request memory is transferred to the device 7A-N.

Therefore, the order in which the commands are executed is performed in the order of requestTime> invikeId> insert.

Therefore, according to the method of the present invention as described above, when the client requests the command to the device at the same time, the command sending module 10 can avoid the overload of the device or the network by distributing the command.

In addition, according to the state of the network, the command sending module 10 may increase the commands that can be sent at the same time to optimize the network by sending a large number of commands when the load of the network or the corresponding devices is light.

After the command transmission process, when the command response receiving interface module 11 receives a response to the command from the device 7A-N via the NE-manager 3, the command response memory register 12 receives the command response memory register 12. requstId Type Extract the command. The command response receiving interface module 11 searches for a user who invoked a command with information extracted from the command response memory register 12 and sends the corresponding client fnh. At this time, if invokeId is a periodic command, since the periodic command module 13 requests the command, the information is stored in the database 5 and then deleted from the command response memory register 12.

In addition, the command response receiving interface module 11 responds to the command 7A-N for a predetermined time in response to a command for which a request time ended by reducing the required time by one second in the command response memory register 12. Since this is not the case, invokeId is extracted to inform the client computer 1A-N that there is no response to the command sent from the device 7A-N.

Here, the cycle command module 13 periodically queries the information of the device and stores the information in the database of the EMS server 2 at a predetermined time.

The periodic command module 13 generates a command at a corresponding time and stores the command in the command request memory register 9 to process the same command as the command sent by the client.

However, the periodic command module 13 is processed with the lowest priority when there are identical terminated commands. That is, the command requested by the user is processed first.

In addition, during the above process, the client computer 1A-N can process the reservation command by giving the request information to the command information. At this time, the current reservation command can be inquired through the command request receiving interface module 8, and the inquiry of such a reserve command means that if the user transmits a reservation command inquiry to the command request receiving interface module 8, the command request receiving interface module ( 8) The requested, requested time, invokeId, and command information of the command are delivered to the user.

Thus, in this way, the user can check the information of the command currently reserved using the transmitted information. Of course, the user may deliver a cancellation command only to the command delivered by the user.

At this time, the minimum command is a command of requestId and invokedId is delivered to the command request receiving interface module 8, where the command request receiving interface module 8 deletes the command using requestId if invokeId is the corresponding client and then deletes the corresponding client. Pass the success to

In addition, according to the present invention, the user may transmit a command that gives priority to all command priorities, which may be indicated by indicating that the command is the highest priority in the priority level among the command information. Then, the command request receiving interface module 8 stores the request time in the terminated state so that the corresponding command is executed first, and stores the command in the head of the command queue so as to process the command in preference to other commands.

Therefore, the present invention can distribute the instructions through such a procedure, and can perform the processing of the reserved instruction, the processing of the periodic instruction, the processing of the highest priority prority instruction, the inquiry of the reserved instruction, and the deletion.

As described in the above description, the present invention distributes user request information by creating a command for reducing a plurality of request times in a process of an EMS, and simultaneously distributes these commands when a plurality of commands are delivered to the EMS server. It has the advantage of preventing overload of network and device connected with optical transmission system.

In addition, according to the present invention, the processing priority is given to all the inputted commands using the request time, and the necessary commands are processed according to the assigned priority, thereby significantly improving the processing efficiency of the EMS.
