This program is intended to analyze IP-traffic in the LAN using flexible mechanism to count IP-packets by interfaces, sender/receiver addresses, TCP/UDP ports, ICMP-services, and so on. It's possible to reset stored data (for example, once per month or year). Results stored in the external file and can be also obtained via LAN by the TVisorClient program.

You can use debug mode to better undestanding of a packets flow, also. Inthis mode info about every packet in the LAN is displayed on screen.
