Description

TECHNICAL FIELD [0001] The present invention relates to a network management system for managing unregistered terminals,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network management system (NMS), and more particularly, to a technology for managing a terminal connected to an Internet telephone (IP telephone) but not registered with network information in an NMS.

A network constructed in an enterprise environment may include an IP exchange, a plurality of switches, terminals such as a plurality of IP phones, a PC, and the like, and an NMS.

Among these, the IP telephone is connected to the port of the switch to perform network communication, and also performs network communication with the IP exchange.

When a terminal such as a PC is connected to a port of an IP telephone, an IP telephone is connected to a port of the switch to perform network communication, or the IP telephone is connected to the port of the IP telephone, Or perform network communication with the IP exchanger directly without going through the IP telephone and the switch or the IP telephone.

In the case where an abnormality occurs in the network state, for example, when a MAC flooding attack occurs in the network, the network manager uses the network information of the network devices stored in the NMS to identify the network device that caused the network abnormal state, For example, to shut down network devices that have caused the network anomaly state. At this time, the network information may include an IP address, a MAC address, and the like of the network equipment. For example, when the network equipment is an IP telephone, the network information of the IP telephone includes information about the switch connected to the IP telephone, the IP address and MAC address of the IP telephone, the port of the switch to which the IP telephone is connected, Address, MAC address, port information of the IP telephone to which the terminal is connected, user information, and the like.

However, since the network information of the terminal connected to the IP telephone is generally used in a state that it is not registered in the NMS, if the cause of the network abnormal state is an unregistered terminal in which the network information is not registered in the NMS The network manager can not quickly grasp the network information of the unregistered terminal. This makes it difficult for the network administrator to invest considerable time in finding the cause of the network abnormal state.

Even if the network administrator invests a considerable amount of time to find and solve the cause of the network anomaly, various types of services through the network due to the network anomaly for a considerable period of time, such as internet telephone service, It is inconvenient for the users who use the various kinds of services.

There is proposed a network management system for managing an unregistered terminal which can easily manage an unregistered terminal which is connected to an IP telephone but is not registered with network information in the NMS.
