Service model and its application to impact analysis

This paper gives a framework for developing Service Models and applying the models to impact analysis and alarm prioritization. We illustrate how the service model concept can be implemented in a service assurance operations center. We also show impact analysis algorithms with respect to a simplified MMS service. The proposed algorithms take into account key Quality Indicators (KQIs), service index, duration of alerts, service Quality of Service (QoS) types, and number of subscribers and allows for deep analytical analysis. The key features include Scalability (based on the idea of Component Status Indicator (CSI)) and Programmable Rules.
