Network implementation of spectrum analysis

摘要

Access devices may receive signals over a network and calculate a frequency spectrum of the received signals. An analyzer system may collect the frequency spectrum data from multiple access devices, and based on the collected data, detect, identify, and locate sources of anomalies in a communication network.

1. A method comprising:
accessing, by a computing device, a plurality of frequency characteristics of signals on a network, the plurality of frequency characteristics corresponding to the signals at a respective plurality of access devices connected to the network; comparing the plurality of frequency characteristics to a plurality of different pre-characterized fault types; determining that a particular type of fault exists in the network based on the comparing; selecting, based on the particular type of fault, a fault detection algorithm from a plurality of fault detection algorithms; and determining a location of the particular type of fault in the network based on the fault detection algorithm and a shape of the plurality of frequency characteristics across a frequency range.
