 Quality of Service (QoS) is a method to prioritize/penalize predefined types of traffic. QoS is a complex topic so this text will discuss only enough basic principles to help you configure an initial setup.

 As shown in the above screenshot, QoS doesn't work when [[advanced-misc|CTF]] is enabled. This is because CTF causes network packets to be routed in hardware, outside of firmware control or monitoring.
