Thanks to the great open source nDPI library NetBalancer v9.7 can now detect the application level protocol of many programs traffic, like BitTorrent, GMail, Skype, etc.

This functionality is named DPI (Deep Packet Inspection) and works by parsing the body of every packet, searching for patterns specific to known applications. The app protocol in NetBalancer is shown for every network connection on the Connections panel (Window>Connections).

And of course NetBalancer also supports rules based on these protocols. So, for example, it is now possible to create rules that will set a low priority for all P2P traffic, will block Skype, limit the Steam traffic and so on.
