Free monitoring network traffic software for windows

Show Traffic application will monitor your network traffic on the chosen network interface and displays it continuously. Show Traffic can be used for locating suspicious network traffic or to evaluate current utilization of the network interface.
It might take some time to display traffic information after starting network monitoring, when Resolve addresses is ON. If you switch it on the fly, it effects only on new connections. Please turn it ON only if you really need it. Once resolved Show Traffic is using its own resolve caching system. Addresses cache got lost when you close the program.
When monitoring is started Show Traffic could decrease network performance of your computer if there is too much network traffic to handle.
