I want to know if there are advantages in using parent queues.
I'll make an example:
I have a wireless uplink with 50Mbps throughput and 5 clients connected to a pppoe server with 20Mbps queue max limit each, so 5 queues 20Mbps/20Mbps.
As far as I know, queues are processed sequentially, so if all of 5 clients wants 20Mbps, in theory the first one should get them, the last one has nothing left.
If I make a parent queue with max-limit 50Mbps/50Mbps on the PPPoE server and those 5 clients' queues children of the first one, what's the result? All of them are going to take 10Mbps, so equally divided, or the first one is the lucky one and get more than the last?
Notice that I want to queue whole clients traffic, not connections, so I don't think PCQ is useful in my case.
Have you got any suggestion?
