I have my mikrotik working as a pppoe server, it makes dinamically simple queues for each client. I am controling the total bandwith with another simple queue. My question is: When is essencial using queue trees??, can i do with simple queues the same as i can with queue tree?? why is called “simple” queue???, thanks.
Yes, ‘queue simple’ allows to accomplish almost all configuration scenarios. The difference between ‘queue simple’ and ‘queue tree’ is given here,

Simple Queue you can use to limit a users/networks upload and download speed.
Queue Tree you can use to make complicated quality of service configurations, to match speficic types of traffic and to do all kinds of advanced things with it.
