Description

Device and method for managing network in network management system

The present invention relates to an apparatus and method for managing a network in a network management system, and more particularly, to an apparatus and method for managing a network in a network management system which minimizes an increase in network traffic and data processing delay caused by an increase in the number of managed devices. It is about.

In general, various protocols are used for communication network management. Regardless of which protocol is used, the information to be passed between the network manager and the device is defined in the Management Information Base (MIB). In the management of communication network, communication equipment is managed by changing and checking the value of specific information using the MIB. The meaning of the MIB and the form of the value obtained through the MIB are predefined. In addition, the MIB is defined as a standard, commonly used for multiple devices, and can be divided into uniquely defined and used only by a specific device.

Among the network management functional areas, the biggest load on the network and the network management system is performance information collection.

As shown in FIG. 1, the network management system manages a plurality of managed devices 20 through a management network by the management server 10, and the managed devices 20 to be managed by the corresponding network management system. If the number of information to be managed according to the management target device 20 is small, the amount of data to communicate in the network for management is small, so it is not necessary to consider a problem such as data reliability or communication network equipment overload. However, as the management target equipment 20 increases, the amount of data being communicated to the communication network increases, resulting in a failure to perform other management functions. The increase in information that needs to be collected causes difficulty in performing other management functions on the processor.

For example, when a control command goes down from the management system to the managed device 20, a delay in the communication network may prevent a reliable command from being transmitted, cause data loss, or cause the processor to operate abnormally.

In addition, the processor related to the capability to collect management information periodically during network management should collect information from the managed equipment at regular intervals. As the number of the managed devices 20 increases, the number of management processors increases and the management information to be collected also increases. Performance-related management processors do not collect information based on network load, but wait for the information to be collected. This is a factor that degrades the performance of the network management system.

Looking at the important elements in the network management system, in particular, as shown in Figure 2, to the network management system for managing multiple nodes, reliable management information should be delivered from the managed device 20. In addition, in the management network, proper communication traffic must be maintained, and in the network management system, there should be no data bottleneck to be processed by the processor due to the appropriate processor load. However, the method of reducing the load on the network management system was not considered. .

The present invention is to solve the general problems as described above, the purpose is to set the data collection cycle to be flexible in accordance with the network situation to eliminate the network traffic increase and the delay of data processing due to the increase in the number of managed devices have.

Network management apparatus in a network management system according to an embodiment of the present invention for achieving the above object includes a management processor for generating a thread for collecting management information to the management target equipment; A scheduling processor for designating a management processor to periodically perform network management and managing the threads; And a thread management function block which is generated by the designated management processor, collects management information from the management target device, transfers the management information to the management processor, and then destroys the management information.

In addition, the network management method in a network management system according to an embodiment of the present invention for achieving the above object comprises the steps of periodically designating a processor to perform network management; Creating a plurality of threads by the designated processor; And collecting management information from the management target device by the thread and delivering the management information to the management processor.

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

The present invention focused on the efficiency of management functions such as failure management, configuration management, charge management, performance management, security management for efficient network management. In particular, when data is collected periodically from the network management system, the management data transmission delay caused by the increase in computer network traffic, which is inevitably generated as the number of managed nodes increases, and a method for minimizing the load on the equipment and the management system is proposed. Implement a network management system.

As shown in FIG. 3, the network management system according to the present invention includes a processor 11 designed to process reliable data in a network management system with management network communication data that increases exponentially as the managed equipment increases in the processor design. ).
