In this case, the prio will change nothing. But if you have 3 classes like : Yes, the prio will change nothing, so it might as well look like this: class parent 1: classid 1:5 htb rate 128kbit class parent 1:5 classid 1:1 htb rate 64kbit ceil 128kbit prio 1 class parent 1:5 classid 1:2 htb rate 64kbit ceil 128kbit prio 1 If we put the client with the guaranteed rate (call him A) into 1:1, and the other two clients (B and C) into 1:2, it should work out the same way. If A uses 64kbit, the remaining 64kbit is split between B and C, and assuming there is a fair qdisc attached to 1:2, they should each get 32kbit. If B is inactive, both A and C will get 64kbit: their classes' guaranteed rates. If A is inactive, 1:2 will hit the ceil and B and C will share 128kbit, so each gets 64kbit. Better, attach 2 new classes to 1:2 : class parent 1:2 classid 1:10 htb rate 16kbit ceil 128kbit prio 1 class parent 1:2 classid 1:20 htb rate 48kbit ceil 128kbit prio 1 Class 10 will get 25% of the available bandwidth of class 1:2 and class 20 75%.

Re: [LARTC] htb guarantee bandwidth
hi, you give to all the clients all the bandwith or limited at 64k, but with different priorities. class parent 1: classid 1:5 htb rate 128kbit class parent 1:5 classid 1:1 htb rate 64kbit ceil 128kbit prio 1 class parent 1:5 classid 1:2 htb rate 64kbit ceil 128kbit prio 2 you put the client that you want to have guaranted 64kbps in 1:1, and the other two in 1:2. it's the clasic example from the devik page.

I have a link of 128 Kbps, and 3 clients. Now i give each of them a bandwidth restriction of 64 Kbps, and one out of them i want guaranteed bandwidth. Now with cbq, i create an isolated class for the guaranteed guy, and i observerd that regardless of the other 2 machines being online, He always gets his allocated 64 Kbps. For htb, since there is no keyword isolated, i created 3 root classes. Also in htb, its documented that root classes do not share from each other. In other words, can i assume that they are isolated? I tried the same scenario as above using htb, but unfortunately the guaranteed machine was not receiving the allocated bandwidth. Has neone doen nething like this?
