It is about.

Here, the correlation analysis refers to the act of linking the failure information managed by the network operation management systems or comprehensively analyzing the failure information in the unit system to identify and act on the actual cause of the failure.

Recently, the domestic and overseas telecommunications business is showing a tendency to open due to the deregulation and relaxation of various regulations. Accordingly, telecommunication service providers are important for the rapid introduction of new services and the provision of high quality services. It is recognized as a factor.

Accordingly, the management of the communication network is very important to the business strategy of many companies, but managing such a network is becoming more and more complicated and difficult, and the increase in the cost of network operation and the management target is complicated and diversified.

On the other hand, conventional network management provides only partial network management through individual network management, and accordingly, there are many problems in overall and comprehensive management of communication networks.

The present invention has been made to solve the problems described above, in order to perform the network management more systematically through the analysis of fault correlation between networks in a comprehensive network management system, traffic control the traffic according to the fault correlation It is an object of the present invention to provide a computer-readable recording medium which records a control method and a program for realizing the method.

The method of the present invention for achieving the above object is a traffic control method using a spatial impairment relationship between heterogeneous networks [switched network and transport network] in a comprehensive network management system, and collects configuration information about the switched network from the switched network management system, When the configuration information about the transport network is collected from the transport network management system, when the fault information about a specific exchange is reported from the switching network management system, or when the fault information about a specific transmission path is reported by the transport network management system, the collected information is collected. Spatially linking configuration information between heterogeneous networks and the reported specific failure information with each other; And resetting a traffic path corresponding to the exchange or the transmission path so that a failure occurring in a specific exchange or a specific transmission path does not affect the other exchange or the other transmission path based on the spatially associated information.

On the other hand, the present invention, a comprehensive network management system having a processor, the function of collecting the configuration information about the switching network from the switching network management system, and collecting the configuration information about the transmission network from the transmission network management system; When receiving fault information on a specific exchange from the switching network management system, or receiving fault information on a specific transmission path from the transport network management system, the collected configuration information between the heterogeneous networks and the received specific fault information are spatially received. Associating with each other; And reconfiguring a traffic path corresponding to the exchange or the transmission path so that a failure occurring in a specific exchange or a specific transmission path does not affect the other exchange or the other transmission path based on the spatially associated information. A computer readable recording medium having recorded a program is provided.

Failure correlation analysis according to the present invention refers to the act of identifying and acting on the actual cause of failure by linking failure information managed by network management systems or comprehensively analyzing failure information in a unit system. There are three types of disability correlations: disability filtering, temporal correlation, and spatial correlation.

First, fault filtering refers to treating a series of faults occurring in the same communication facility as one specific fault depending on the dependencies between the faults. This type of fault handling is handled by the unit network management system.

Second, temporal correlation is about disability handling when events related to a specific disability situation occur periodically, and it measures by analyzing correlation with disability patterns that occurred in the past.

Third, spatial correlation refers to the analysis of obstacles that transition according to the dependence of the network configuration. That is, it analyzes and measures the effect of the failure in one facility of the communication network on another communication facility. In this case, information on the overall configuration situation and interrelationship according to the communication network configuration is required. The present invention provides a traffic control method according to spatial correlation.
