<p>Disclosed are a method and apparatus for correlation analysis of layered network alarms and services, wherein the method including: constructing the whole network service layer topology structure, where the relationships of connected services in adjacent service layers are client layer service and server layer service from top to down; relating alarms reported by network elements to services according to correlation rules; on the basis of the whole network service layer topology structure and alarms related to services, determining local layer alarm status and server layer alarm status of the services. This invention enables network management system to obtain local layer alarm status and server layer status according to the relationships of alarms reported by network elements and services on the network elements and further to estimate the number of services affected by alarms and the influence degree, thereby analyzing service fault status, accelerating the positioning of critical network failure and reducing operation and maintenance cost. This invention makes the positioning of critical network failure more efficient by suppressing derivative alarms, decreasing the number of alarms reported by network elements and filtering out more important alarms.</p> |
