Abstract:
Unavailable customer bandwidth in a connectionless IP network ( ) is determined by first measuring network accessibility and network continuity (in Defects Per Million) via an accessibility measurement instrumentation device ( ) and a continuity measurement instrumentation device ( ). The accessibility and continuity measurements are combined via a mechanism ( ) to yield a service unavailability measure that is then compared to a threshold value, representing the applicable customer unavailable bandwidth specified under an service level agreement specification ( ). If the actual service unavailability exceeds the allowable unavailable customer bandwidth under the service level agreement, then an event correlation device ( ) will correlate the service unavailability measure with network fault and performance alarm information from network alarms ( ) to establish a root cause. Once the route cause is established, a trouble ticket system ( ) generates a trouble ticket to facilitate network restoration.
