Wireshark is perhaps one of the best open source packet analyzers available today. However, with the advent of Wireshark, all that has changed. In the past, such tools were either very expensive, proprietary, or both. You could think of a network packet analyzer as a measuring device used to examine what's going on inside a network cable, just like a voltmeter is used by an electrician to examine what's going on inside an electric cable (but at a higher level, of course). A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible.
