Meanwhile, referring to the physical architecture of the COMS, as shown in FIG. 4, the COMS constructs a network management infrastructure by using a commercial network management platform 80, TIPIP (TeMIP). TeMIP provides mapping processing, management domain establishment, and mapping management mapping by management domain, and supports management information exchange based on 'SNMP / CMIP / ASCII-based protocol'.

Physically, COMS is a network management platform (TeMIP) 80, DB server 84, Web server (83), communication server 81 for collecting alarm events and control commands, and periodically It consists of a performance data collection server (82) for collecting the performance information of the network components.

The physical structure of the COMS having the above configuration has the following advantages.

First, COMS collects management information messages through two communication servers 81, thereby preventing the loss of important alert events that may occur due to the overhead caused by periodic performance data messages.

Second, by building a web server 83, it is possible to provide a management service to all operators who can access the network.

Third, by separating the DB server 84 and the web server 83 and continuously updating the DB tables in the DB server 84, the time for the web server 83 to load data into many web browsers. Can be shortened.

Fourth, by placing the network management platform and the two management communication server 81 in the same LAN, so that the information exchange by SNMP does not affect the web server 83 and DB server 84, at the same time a lot of communication load By connecting another LAN between the web server 83 and the DB server 84, web computing performance can be maximized.

The information flow of each part performing the function of each service part as described above is as follows.

As shown in FIG. 5, the integrated management service unit 20 of the COMS has a structure that accommodates the standard MIB as much as possible, and the manager 10-1 in the COMS 10 is the COMS matching device 12. A management command is sent to a management agent (Agent) 12-1 within, and the management agent (12) responds appropriately based on the contents stored in its SNMP MIB 12-2.

In addition, the management agent 12-1 reports the occurrence and the contents of the event to the manager 10-1 through a trap at the time of detecting the state change of the management targets and the periodic performance measurement.

The SNMP MIB 12-2 of COMS models management objects such as various protocols, hosts, relational databases (RDBMSs), routers, and LAN switches in the CT-2 operation center.

COMS failure monitoring service unit 30 is as shown in Figure 6, which provides a basis for immediate action by monitoring the failure status of the CT-2 national network components in real time.

First, when the failure monitoring service unit 30 receives the SNMP alarm traps from the integrated management service unit 20 to collect alarms for each management domain and display the alarm contents, update the configuration information of the configuration management service (update) The function, the fault handling task allocation function of the fault handling service, and the alarm storage function are transferred (S1).

Second, the alarm display function receiving the alarm content outputs the alarm content on the screen (S2).

Third, the alarm storage function stores the alarm in the corresponding DB table (S3).

Fourth, the failure statistics analysis function periodically generates statistical data by analyzing the stored alarm contents (S4).

Finally, the statistics / trend presentation function allows the output of the processed data to the web browser (S4).

The COMS fault handling service unit 40 is a unit that provides a mechanism for analyzing and assigning a fault recovery operation to an operator by analyzing an alarm event. As shown in FIG. As to the flow, firstly, the fault handling service unit 40 outputs a related alert content, a work delivery method, and a list of operators when the alarm contents are delivered from the fault monitoring service unit 30. (T1).

Second, on the basis of the screen, the task is assigned to the operators of the management domain in which the alarm has occurred, so that necessary actions can be promptly performed (T2).

Third, it provides a screen for operating personnel to input the result of the troubleshooting (T3).

Finally, the failure management result is transmitted to the configuration management service unit 60 to update the shape of the network according to the failure processing result (T4).

The performance monitoring service unit 50 collects performance information periodically and analyzes various performance statistics and trends, thereby providing a basis for preventing failure factors of the CT-2 network in advance. The service unit 50 collects performance data periodically transmitted from the integrated management service unit 20 for each management domain (E1).

Second, the collected performance data is stored in the DB table (E2).

Third, analyze the performance statistics and trends of the management targets based on the stored performance data, and send the alarm corresponding to the management targets exceeding the predetermined threshold value to the failure monitoring service unit 30 so that appropriate resolution can be made (E3). .

Finally, the analyzed result is referred to the operator through a web browser (E4).

The configuration management service unit 60 is a management service unit for managing the configuration information of the CT-2 nationwide network and expressing the status information. Looking at the flow, first, the configuration management service unit 60 is a failure monitoring service unit 30. The network status information is updated based on the alarm contents transmitted from) or the alarm processing contents of the fault handling service unit 40 (M1).

Second, it outputs the current network shape information and state information on the screen so that the operator can determine the network shape and state, and also provides a screen for the operator to request detailed network shape and state information (M2).

Finally, the operator's request is transmitted to the integrated management service unit 20 to be sent to the COMS matching device through SNMP operation, and when the result of the request arrives from the integrated management service, the result is output to the operators (M3). ).

The operation performance analysis service unit 70 provides a basis for analyzing statistics and trends of operation performance by center, regional headquarters and nationwide through periodic DB-DB queries. Through the DB-DB interworking function of the management service unit 20 periodically collects the operating performance data of the operation center and stores it in the DB table (N1).

Second, it is possible to evaluate the operation status of the operation center, regional headquarters, and nationwide through statistical and trend analysis of stored performance data (N2).

Finally, the operator can refer to the necessary data through the web browser (N3).

As described in detail above, in order to efficiently manage the CT-2 nationwide network, the present invention introduces a web computing technology widely used in network management to build a management system so that operators can refer to management information regardless of location. There is an advantage in providing a foundation to enable this, and the following effects will be achieved through future COMS development.

Through the standard network management interface, heterogeneous equipments can be integrated and managed, and the service quality of CT-2 national network can be improved through real-time fault monitoring and processing.

In addition, it is possible to maximize the utilization of the existing management system by performing management tasks by dividing the management domains, and to prevent the expected degradation of service quality through performance analysis of the CT-2 nationwide network. By allowing management information to be accessed, the CT-2 network can be managed regardless of the operator's location.

Also, by placing web server and DB server in the same LAN and the TIPMI and communication servers in another LAN, it is possible to minimize the overhead of management communication and server-to-server communication, and to manage based on standard management service design technology. Implementing services has the advantage of being reusable for implementing future management functions.
