Abstract
The disclosed methods and systems prioritize network devices and components that more likely result in a network outage by evaluating their current and historical outage information relative to a dynamically-generated, statistical threshold based on such outage information. The prioritized list of network devices can be organized by, for example, quantity of outages, number of outage minutes, and/or number of customer-outage minutes so as to provide diagnosis sequences by type of network device, network location, type of component within the network device, and/or by operation during particular time periods/events.
Claims28
A method of identifying a source of fault patterns in a telecommunications network, method comprising:
- accessing historical and current fault data associated with operations of a plurality of network devices in the telecommunications network;
- identifying at least a subset of the fault data associated with an at least one filter criterion;
- dynamically generating a set of statistical metrics from the subset of fault data, the statistical metrics including at least one threshold;
- and
- prioritizing the subset of fault data relative to the threshold, the prioritized fault data identifying an ordered list of at least some of the network devices exhibiting operations exceeding the threshold.
A system for identifying a source of fault patterns in a telecommunications network, the system comprising:
- a data-acquisition process coupled to the telecommunications network, the data-acquisition process accessing historical and current fault data associated with operations of a plurality of network devices in the telecommunications network and identifying at least a subset of the fault data associated with an at least one filter criterion;
- a statistics process dynamically generating a set of statistical metrics from the subset of fault data identified by the data-acquisition process, the statistical metrics including an at least one threshold;
- and
- a priority process coupled to the data-acquisition process and statistics process, the priority process prioritizing the subset of fault data relative to the threshold, the prioritized fault data identifying an ordered list of at least some of the network devices exhibiting operations exceeding the threshold.
A method for identifying a source of fault patterns in a telecommunications network, the method comprising:
- accessing historical and current fault data associated with operations of a plurality of network devices in the telecommunications network;
- identifying at least a subset of the fault data associated with at least one filter criterion, said at least one filter criterion relating to at least one of device type, network location, component type, time, and event type;
- dynamically generating a set of statistical metrics from the subset of fault data, the statistical metrics including at least one threshold;
- prioritizing the subset of fault data relative to the threshold, the prioritized fault data identifying an ordered list of at least some of the network devices exhibiting operations exceeding the threshold;
- and
- determining from the ordered list a set of problem-prone network components, whereby the source of fault patterns in the network is identified.
