Real-time monitoring of service performance through the use of relational database calculation clusters

摘要

A system and method for monitoring service performance are disclosed. In a preferred embodiment, the method comprises: (a) collecting service information from one or more sources in a telecommunications network; (b) converting the service information into values of primary parameters of a service model; and (c) calculating values of secondary parameters of the service model from the primary parameter values, wherein the calculating is performed using relational database tables based on calculation clusters. The calculation clusters are preferably determined from a hierarchical model of the service by dividing the hierarchy in a manner that separates shared service components from the service components that share them, and that separates service components related by 1-to-n and n-to-1 relationships.
