Power fluctuation detection and analysis

摘要

The network monitoring system collects transmission and/or receive power level information from a plurality of customer premise devices connected to the same distribution node for each of a plurality of network distribution nodes. For an individual network distribution node, the network monitoring system calculates a set of fluctuation parameters including a group power level deviation metric, e.g., a modified standard deviation ratio. The network monitoring system evaluates the generated fluctuation parameters and responds, e.g., outputting a fluctuations report, modifying a data collection profile being used by a set of customer premise devices corresponding to a distribution node, commanding diagnostics to be performed on a portion of the network and/or directing a service technician. The network monitoring system compares generated fluctuation parameters corresponding to different distribution nodes, and uses the results of the comparison to assign priority with regard to the assignment of limited available troubleshooting and repair resources.

主权项

1. A method of monitoring a communications system comprising:
operating a monitoring device including a processor and memory to perform the steps of: collecting at least one of transmission power level information or received power level information from a first plurality of customer premise devices corresponding to a first network area; collecting at least one of transmission power level information or received power level information from a second plurality of customer premise devices corresponding to a second area; generating a measure of network instability for the first network area based on power level fluctuation information included in collected power level information received from said first plurality of customer premise devices; generating a second group power level deviation metric from collected power level information received from said second plurality of customer premise devices, said second group power level deviation metric being a modified standard deviation ratio; and taking an action based on the measure of network instability.
