Abstract

A telecommunications network management system that continuously monitors aggregated service performance is disclosed. The system preferably employs a service model having a hierarchy of user-defined service components, each having one or more parameters. A given service may have multiple instances, each instance corresponding to a different locality. Alternatively, or in addition, the service parameters may have customer-dependent values. The system o includes a data collector component and a performance data manager component. The data collector component receives service information from one or more sources in a telecommunications network, and converts the service information into values of primary parameters of a service model. The performance data manager component calculates values of secondary parameters of the service model, and stores the parameter values in a database. The performance data manager component further determines aggregated parameter values from multiple instances and/or multiple customer-dependent parameter values. The aggregated parameter is stored in the performance data database.
