The present invention relates to a method for automatically registering a managed object in a common object request broker architecture (CORBA) based network management system (NMS), and in particular, to manually register a managed object managed by a network management system. In order to remove the inefficiency caused by the management, the agent actively registers its information with the network management system when the agent is running on the network so that the management object can be automatically registered in the network management system without the control of a separate operator. The present invention relates to an automatic registration method of a management object in a COVA-based network management system that is suitable for reducing the management cost required for the operation and reducing the possibility of an error that may occur during the control by the operator.

In general, network management refers to a function that constantly monitors the status of international communication networks and takes measures to control the inflow as necessary to enable maximum traffic communication under any circumstances. And NMS (Network Management System) is a computer system to support such network management tasks, and performs the following functions. That is, it collects and accumulates network status, alarm, traffic data, etc. from transmission equipment. Calculate network management parameters or statistical data. Command to control the traffic inflow of the transmission equipment. Controls network monitors and network control terminals of network management centers.                         

Currently, many network management systems have been developed based on CORBA (Common Object Request Broker Architecture), which has good system flexibility and scalability with other systems. CORBA is a structure and specification for creating, distributing, and managing distributed program objects on a network. It allows programs located at different locations on the network and developed by different vendors to communicate through an interface broker.

In addition, the network management system stores the configuration information, configuration information, service information, and performance information about the managed systems constituting the network so that the network operator (manager) can manage the network in a database and other storages. By matching the information with the equipment, it provides the operator with the information necessary for network management if necessary, and monitors the fault information generated from the network components in real time and informs the administrator.

In order to monitor and manage the network through a network management system that performs these functions, a procedure for registering a management target is required.

To this end, the network management operator conventionally inputs basic information (name, IP (Internet Protocol) address, coordinates, etc.) about the management target, and the network management system based on such information, the agent and management mounted on the management target. It is done by exchanging information.

Therefore, according to this method, the engineer installs the equipment to be managed at the beginning of network construction, and informs the operator of the network management system monitoring station about the basic information on the management, and the operator registers the management object to the network management system according to the above method.

In particular, when the initial network is configured, the management target system is frequently installed and tested. Accordingly, the management target is frequently registered and deleted in the network management system, resulting in inefficiency in the management task of the operator.

In addition, if the information necessary for registration of the management object is inputted incorrectly, there is a high possibility of causing a malfunction.

1 is a block diagram of a general KOVA based network management system and its peripheral devices.

Here, reference numeral 10 denotes an operator interface such as a workstation that allows an operator to perform network management, 20 denotes a network management system for managing a network, and 30 denotes a management target device managed by a network management system.

In addition, reference numeral 21 is a configuration management server (Configuration Management Server, CMS) for managing the configuration in the network management system, 22 is a database (scheduling) to store the scheduling information (Database, DB), 23 is a managed device ( A network monitoring server (NOS) connected to 30 monitors a node, and 24 is a fault management server for managing faults by receiving information when a fault occurs from an agent of the managed device 30. FMS), and 31 is an agent of the managed device.

Thus, the operator inputs basic information (name, IP address, coordinates, etc.) about the management object through the operator interface 10, and the network management system 20 manages the agent and management mounted on the management object based on this information. Network management is performed by sending and receiving information.

2 is a flowchart illustrating a method of registering a management object in a conventional COVA based network management system.

As shown therein, a step of making a registration request from the operator interface 10 to the configuration management server 21 (ST1); Receiving the registration request, the configuration management server 21 requesting registration to the node monitoring server 23 (ST2); The node monitoring server 23 fetches an interoperable object reference (IOR) of the agent 31 of the managed device 30 (ST3); Storing the IOR patched from the node monitoring server 23 to the DB 22 and notifying the configuration management server 21 of completion of registration (ST4) (ST5); Patching the IOR of the DB 22 in the configuration management server 21 and then requesting management information to the agent 31 of the managed device 30 and delivering the IOR of the failure management server 24 ( ST6) (ST7); In step ST8, the configuration management server 21 notifies the operator interface 10 of the registration.

The operation of the prior art configured as described above will be described in detail with reference to the accompanying drawings.

3 is a block diagram showing that the conventional method of FIG. 2 operates in the COVA-based network management system of FIG.

So, when the operator inputs basic information (name, IP address, coordinates, etc.) for the management object to be managed by the network management system 20 using the operator interface 10, a registration request is made to the configuration management server 21. Is sent.

The configuration management server 21 receives the registration request and requests a registration to the node monitoring server 23.

The node monitoring server 23 obtains an IOR and stores it in the database 22 in order to establish a COVA-based connection from the management object. For this purpose, the node monitoring server 23 patches the IOR of the agent 31 of the managed device 30. The node monitoring server 23 stores the IOR patched to the DB 22.

When the node monitoring server 23 notifies the configuration management server 21 of the completion of registration, the configuration management server patches the IOR of the DB 22 and brings the agent of the managed device 30 using the promised COVA communication. 31) request management information, and delivers the IOR of the failure management server 24 at the first request.

Finally, the configuration management server 21 notifies the completion of registration to the operator interface 10, that is, the screen module, and displays it on the screen.

After registration, the agent 31 mounted on the management object returns a management information corresponding to the request for management information from the configuration management server 31, and in case of a failure, the IOR of the failure management server 24 previously received. Will be sent.

However, this conventional technology has the following problems.

To monitor and manage the managed devices that make up the network through the network management system, registration procedures for them are required initially. In the past, these processes were performed by the operator one by one, and in order to do this, the operator must not only recognize the correct operation procedure but also have to grasp the correct information necessary for registration.

At this time, if there are more management targets to manage, there is more information to be memorized or maintained by the operator, which increases the probability of error occurrence.

In particular, in the early stages of network construction, the system to be managed is frequently installed and tested. As a result, the network management system frequently registers and deletes a managed object, which causes inefficiency in the management task of the operator.

In addition, there is a problem that the network management system itself is more likely to cause a malfunction if the information necessary for registration of the management target is incorrectly input.

However, in most network management systems, such a manual information input procedure is adopted, and thus there is a problem that becomes a big obstacle in increasing the reliability of the network management system.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is to remove the inefficiency of manually registering a managed object managed by a network management system. Actively registers its own information with the network management system when it is running so that management targets can be automatically registered in the network management system without the control of a separate operator. It is to provide an automatic registration method of a managed object in a COVA-based network management system that can reduce the possibility of error.                         

In order to achieve the above object, in the KOVA-based network management system according to an embodiment of the present invention, an automatic registration method of a management object is provided.

In the first steps ST11 to ST14, basic information is transmitted from the agent 31 of the managed device 30 to the network management system 20 by using a Trivial File Transfer Protocol (TFTP). It characterized in that for transmitting the IOR.

In the first step ST11 to ST14, the node monitoring server 23 periodically monitors a designated directory for a newly registered management object, and checks whether a file of a suitable format exists when a new file is created in the designated directory. After that, the basic information and the IOR are parsed.

In the first step ST11 to ST14, the node monitoring server 23 parses the basic information received from the agent 31 of the managed device 30 and the IOR by parsing the IOR. After testing using Ping), if appropriate, it is stored in the database 22 and notified to the configuration management server 21 that a new management object is registered.

In the first step (ST11 ~ ST14), the step (ST11) of transmitting the IOR containing the basic information from the agent 31 of the management target equipment 30 to the network management system 20 using TFTP; Parsing basic information and an IOR received from the agent 31 of the managed device 30 by the node monitoring server 23 after the transmission (ST12); After parsing, the node monitoring server 23 stores the IOR in a database 22 (ST13); After the storage, the node monitoring server 23 further includes a step of notifying registration to the configuration management server 21 (ST14).
