cFosSpeed screenshotFirst cFosSpeed tries to identify the Layer 7 Protocol for every connection. If it is not discovered (i.e. the protocol is unidentified) or the priority of the discovered protocol is "normal", then the program discovery is used to designate the priority.

An unique case is the HTTP stream disclosure. If the noticed protocol is HTTP, the application tries to identify, if it is a video and audio stream. This works like that:

If the user operator is one of the common players or has the substring player in it, the utility classify the connection as HTTP_STREAM_C and HTTP_STREAM_S. Alternatively if the content-type is audio and video it classifies the connection as BSTREAM_C and BSTREAM_S. The BSTREAM_C/S connections are registered as "normal" so that the priority is designated by the program prioritization.
This enables you, for example in some cases, to prioritize it according to your software use.

Prioritization - Your essential streams first

You can set the priority of the most popular network protocols, so all software using it automatically have the correct priority. Additionally you can customize the priority of particular programs. This means downloads don't cause lag while the user plays games or viewing videos, for example.

Survey of connections and easy prioritization of connections

You can see very easy which software are consuming your bandwidth. cFosSpeed let's you temporary customize the priority to speed up transfers or lower latency for time-critical utilities.


  • Monitoring of your connection.
  • Prioritizing of applications over others.


  • Requires all the PC in LAN to have the program installed for best usage.
