# Protocols

Protocols page provides three pie charts and a specific table with nDPI-detected protocols for the selected interface.

In the two top pie charts ntopng shows the application distribution and its categorisation. The bottom pie chart shows nDPI-detected applications for currently active flows. All labels are clickable and point to detailed statistics pages. Belo pie charts there is a list of protocols detected with the corresponding total traffic, both in absolute terms and as a percentage of the total traffic. By selecting any Application Protocol, it is possible to display a statistics page with temporal charts for that protocol. Similarly, by clicking on the magnifying lens icon, it is possible to display all active flows for that protocol.
