Abstract
A method and system for analyzing network traffic are provided. A network traffic analyzer includes a plurality of data switching devices connected to a plurality of data hubs. Each data hub may have multiple input ports and multiple output ports and may be configured to broadcast all data packets received at an input port to all output ports. Each data switching device may be configurable to forward data packets to an input port of any one of the plurality of data hubs, any subset of the plurality of data hubs, or all data hubs of the plurality of data hubs, based on a characteristic of one or more data packets. Furthermore, at least one network sensor device may be connected to an output port of a data hub of the plurality of data hubs. The network sensor device may be configured to analyze data packets in real time for, among other purposes, detecting network intrusions.
