Alarm correlation system
View Patent ↗Network applications rely on ever-increasing diverse and complex transport service mechanisms. A transport service between points in a network often traverses multiple technologies involving numerous containments and adaptations. A network event affecting the transport service may occur in any number of elements supporting the transport service, resulting in a myriad of alarms. Prior techniques for suppressing alarms involving complex network information models and coding logic to reduce the number of alarms presented, but require additional steps before the network event can be troubleshot and resolved. In contrast, the provided alarm correlation technique presents a highly structured and comprehensive visual presentation depicting the network event affecting the transport service in terms of the supporting elements affected by the network event. The provided visual presentation enables a viewer to visually correlate the network event affecting the transport service with the transport service affected by the network event directly.

representing a network event affecting the transport service to form a representation of the network event; and
simultaneously presenting the network event representation against the complete representation of the transport service to provide a visual presentation of the network event affecting the transport service in terms of the affected physical network elements, network entities, and connections, the provided visual presentation enabling a viewer to correlate in a visual manner the network event affecting the transport service with the transport service affected by the network event.
