Abstract

A system and method for determining service requirements of elements in a network. A collection program is used to gather performance data from an element for which a service requirement is desirable by an entity. The performance data is stored in a database. The performance data is then retrieved by a microprocessor. The microprocessor processes the performance data to calculate a network health indicator associated with the performance data. Using the network health indicator, a service requirement of the associated element can be determined. When at least two network health indicators or service requirements of different elements are compared, service priorities among the elements can be established.
