FRITZ!Box can grant priority to important network devices and applications in the local network when the Internet is working at capacity.

You can specify here that certain network devices and network applications have priority over others when the Internet connection is busy.

Applications with high demands on transmission speed and reaction times (e.g. Internet telephony, IPTV, video on demand).
If an application of this category uses the Internet connection to full capacity, no other data will be transmitted.

Network Device	Network Application
automatic	Internet Telephony
automatic	FRITZ! Media Video Streaming
No real-time applications are running at this time

Applications that require a fast reaction time (e.g. company access, terminal applications, games).
The following applications will be granted high priority. When an application of this category uses the full capacity of the Internet connection, the data of other applications will be transferred with lower priority.

Applications that run in the background and are treated with low prioirty when the Internet connection is running at capacity (e.g. automatic updates, peer-to-peer services)
