With the EdgeXOS platform you can not only perform traffic shaping and QOS, you can also perform full application policing, i.e. rate-limiting.
Example: You can rate limit web traffic to 128Kbps, or FTP traffic to 50Kbps, etc. regardless of other traffic conditions.
This policing can also be applied on a per user basis, so that User A gets 10Kbps, and User B gets 20Kbps, etc.
