Services provided by telecom operators rely on network infrastructure. Hence, every network operator has centralized network management center (official names vary), established for managing network (tracing current network status, triggering restoring actions etc.). Global network problems are represented by sequence of alarms (faults) from network resources. In our previous papers, we have focused on alarm correlations leading toward automatic global network problem recognition. This paper defines the model of integrated view on telecommunication network, integrating more sources of real-time data in the unique network view. We have used multi-level model for network presentation. This model enables global network view on the top level, with drill-down possibilities toward details hidden in lower levels. Network elements have their own attributes, recalculated periodically from network data. Based on object attribute's values and predefined threshold values, the object status is recalculated as well. In the network presentation model, object status data from lower levels are propagated to the top level using propagation rules. The top view gives global network status overview, integrating data from different sources. Integrated data sources are fault and performance data as primary, and end-to-end testing results as well as customer's trouble tickets as secondary sources.
