Packet network monitoring device

摘要

A network analysis device for a digital communication network includes a digitizer to digitize a waveform representing a signal to produce a plurality of digital samples indicative of the waveform. The signal is communicated on the network. The network analysis device also includes a processor operable to analyze the digital samples to identify signal events, determine analog characteristics of the signal events, and decode the signal events, which are digital communications between network devices, based on the data, to selectively predict a failure mode.

1. A method for monitoring a network, comprising:
digitizing a waveform representing a signal to produce a plurality of digital samples indicative of the waveform, wherein the signal is communicated on the network and wherein the waveform is digitized at least at one of:
a rate greater than is required to minimally detect digital transitions in the signal; anda resolution greater than is required to minimally detect digital transitions in the signal; analyzing the digital samples to identify signal events; determining analog characteristics of the signal events; and classifying the signal events, which are digital communications between network devices, based at least in part on the analog characteristics, to selectively predict a failure mode.
