ABSTRACT:
A signaling network management system (SNMS) collects network topology, traffic, performance and fault information, correlates that information and displays the information to system operators. It includes a distributed client/server platform that receives and processes information relating to network events that is generated by various signaling network elements. Each network event is parsed and formatted to a standardized format to allow processing of events generated by any type of element. The formatted events are correlated and displayed to system operators. Correlation of the different types of events is performed using programmable analysis rules. The system also correlates signaling network events with transmission alarms and network maintenance schedule information. This allows the system operators to account for outages due to transmission events, such as fiber cuts, and to network maintenance. It also allows operator to worn maintenance personnel of maintenance impacting events. The system employs extensive topology processing of both carrier-owned and foreign networks. This allows system operators to perform impact assessments, such as which customers are affected by specific events. The system provides a graphical interface to operators that allows localized displays, so that only events and impacts pertaining to a specific STP cluster or LATA, for example, are shown. An interface to an external trouble management system allows system operator to submit trouble tickets for signaling network events, without the restriction of a proprietary trouble management system.
