Since ROS v6 so-called double QoS is not possible as used to be based on http://mum.mikrotik.com/presentations/C ... _Megis.pdf.

I have managed either priorities for services DNS, 3-way-handshake, web browsing, heavy traffic or PCQ.

Service priorities are great, but one user kills it for others very easily.

PCQ is great, and guarantees bandwidth for each user, but there are no priorities per user. If I one user downloads, and still wants to web browser it will be slow.

Did anyone manage to do double QoS on > ROS v6, please?

My idea is based on https://help.mikrotik.com/docs/display/ROS/PCQ+example

Is it possible to add child queues where PCQ is parent?

I want DNS, SYN, SYN-ACK, ACK small packets high priority, and heavy traffic the lowest prio.

Any suggestions, please
