Abstract

A plurality of network analyzers are combined into a network performance analysis tool for analyzing complex and widely distributed networks. Each of the network analyzers is synchronized with the others to provide consistency in the application of timestamps to packets traversing the network. Data from all of the analyzers is aggregated and sorted chronically and a variety of processing performed to determine important performance information about various components of the network. This information can then be used directly in simulation of a fully deployed network environment.
