TNV (The Network Visualizer or Time-based Network Visualizer) depicts network traffic by visualizing packets and links between local and remote hosts. It is intended for network traffic analysis to facilitate learning what constitutes 'normal' activity on a network, investigating packet details and security events, or for network troubleshooting. It can open saved libpcap (from tcpdump, windump, ethereal, etc.) formatted files or capture live packets on the wire, and export data in libpcap format or save the data to a MySQL database to enable the examination of trends over time.
