Old school "QoS" prioritized traffic by type. Modern Active Queue Management (AQM) solves the root cause: the buffer size.
How CAKE Works
The CAKE algorithm actively measures the link speed. If it detects the buffer filling up, it drops packets before the buffer is full.
This signals the sender to slow down. The result? You can download at 95% of your total speed while your ping remains flat. This is mandatory for gaming households.
