Abstract:
1. A network fault management system for reporting and correlating network faults, comprising: a local notification collector for receiving fault notifications generated by managed entities; said managed entities include distinct components and sub-systems; said local notification collector is a local network component which is programmable to avoid fault notification flooding by programming its task priority setting to a higher task priority than all other tasks that generate fault notifications thereby preventing managed entities from generating fault notifications while said notification collector is processing a fault notification, each of said managed entities includes its own identity, a state change occurs when one of said managed entities goes from a fully functioning state to a fault state, when a state change of a managed entity occurs, notification of the state change and the identity of said managed entity are transmitted to said notification collector, when a state change of a managed entity occurs, said managed entity sends a state change message to all dependant managed entities that depend on said managed entity along with the identity of the managed entity which was the root cause of the fault state, said notification collector sends notifications of state change to a management system, and said notification collector includes a programmable threshold; said programmable threshold depends upon bandwidth of the communication link, capacity of the management system and amount of notification buffers.
