In the first path, a portion of the data input to the backbone switch 106a via the router 104a is transmitted to the firewall 110a while maintaining the flow of the first path, but some portion of the data is transferred to the L4 switch 108a. Passed through to the backbone switch 106b of the second path and forwarded to the firewall 110b.

In the second path, a portion of the data input to the backbone switch 106b via the router 104b is transmitted to the firewall 110b while maintaining the flow of the second path, but some of the data is transferred to the L4 switch 108b. It passes through the backbone switch 106a of the first path and is sent to the firewall 110a. That is, data in the first path and the second path are exchanged with each other to achieve data load balancing.

Outputs of firewalls 110a and 110b are connected to backbone switch 112a and backbone switch 112b.

In the first path, part of the data input to the backbone switch 112a through the firewall 110a maintains the flow of the first path and is transmitted to the interface server 116a, but a predetermined part is the L4 switch 114a.

In the multi-path data management system of the first embodiment of the present invention, when a failure occurs in some of the network devices of the data path, the system manager finds an alternative data path composed of the network devices without the failure and transmits the data. Data can be managed reliably.

Hereinafter, when an error occurs in the data path, the operation of the data management system of the first embodiment of the present invention will be described.

4 is a data flowchart when an error occurs in one router constituting the data management system of the first embodiment of the present invention.

As shown in FIG. 4, when an error occurs in the router 104a and it is down, the downed router 104a and the backbone switch 106a report the fault to the central monitoring unit 129 through the wireless LAN.

The central monitoring unit 129 configures a data path using the router 104b that operates normally, and transmits a command to the router switching unit 102 to switch the data flow to the router 104b. At the same time, the central monitoring unit 129 reports this to the system operating unit 130 and notifies the system administrator of the failure by using the wireless communication module.

The router switching unit 102 receives a switching command from the central monitoring unit 129 and transmits all data to the router 104b in normal operation. The router 104b receiving the data includes the backbone switch 106a and the backbone. Data is sent to the switch 106b.

At the same time, the central monitoring unit 129 reports this to the system operating unit 130 and notifies the system administrator of the failure by using the wireless communication module.

In this case, the data passing through the firewall 110a is transferred to the backbone switch 112b without any abnormality, and all data is transmitted to the backbone switch 112b with no abnormality.

The backbone switch 112b receiving the data divides and transmits the data to the interface server 116a and the interface server 116b without transmitting the data to the backbone switch 112a through the L4 switch 114b. The subsequent data flow proceeds in the same way as the normal normal data flow of FIG. 3.

Hereinafter, a method of managing a database system using a data management system according to a first embodiment of the present invention will be described.

6 is a conceptual diagram of a data management method using a data management system according to a first embodiment of the present invention.

As can be seen in FIG. 6, when a network device constituting the data management system of the first embodiment of the present invention fails (310), the network device connected to the failed network device and / or the failed network device is failed. The device transmits the network device failure information to the system manager 128 (320).

When the system manager 128 receives the abnormality information of the network device from the network device, the system manager 128 transmits the failure information of the data management system to the system manager (330).

At the same time, the system manager 128 transmits a transfer command for switching the data flow to a path constituted by a network device that does not fail, to a network device that is connected to the network device that has failed. The network device receiving the transfer command transfers the data flow to the path where the failure does not occur (350).

According to the data management method of the present invention, in the event of a network device failure, the system manager immediately notifies the system administrator, and newly configures a data path using only the network device that has not failed, and performs a data flow with the configured path. Transfer.

Therefore, the system administrator can immediately recognize the failure of the data system, and can stably manage the data even before the failure of the system is repaired, thereby improving the reliability of the system.

Hereinafter, as a specific example, a data management method of the first embodiment of the present invention will be described in detail taking a case where a failure occurs in a router among network devices.

7 is a conceptual diagram of a data processing method of a data management system according to a first embodiment of the present invention when a router fails.

As shown in FIG. 7, when an error occurs in one of the routers 104a and 104b connected to the router switching unit 102, the router in which the error occurs and the backbone switch connected to the router are connected to the system manager 128. Fault information is sent (420).

Receiving the router failure information, the system management unit 128 transmits the failure information of the router to the system administrator (430), and at the same time to the router switching unit 102 to transfer the transfer command for switching the data flow to the router does not fail (440).

The router switching unit 102 receiving the router switching command switches the data flowing to the failed router to the router in operation (450).

The system manager receiving the router failure information repairs the failed router based on the received router failure information (460).

The data management system of the present invention has a structure in which a state of each device is transmitted to a system management unit by a wireless communication module and is processed, unlike a method in which various devices are connected to the system management unit by a conventional wire. In addition, the system manager has a means for taking necessary measures when an abnormality occurs and at the same time notifying the system administrator.

In this structure, even if an error occurs in the wired LAN, it is possible to recognize the failed device immediately, and even if the operator does not always look at the monitor of the central monitoring device, it is easy to grasp the abnormal condition of the data management system anytime and anywhere in real time.

On the other hand, if a network device included in the data path fails, the system manager configures a new data path using normally operating network devices around the failed network device, and sends a path change command to each network device. By transferring the data, the data flow path is switched over to a functioning data path so that data can be stably managed.
