> 1) 6kbit is really too small it should be at least 10 ..
I tried with 12, 20 and even with 30kbit for 1:3
I noticed, that it work for some seconds (or 1-2 minutes) but than the 1:3 class gets more then it should get :(.

I made a test with settings: ---------------------------------
tc qdisc del root dev eth0 tc qdisc add dev eth0 root handle 1:0 htb default 3
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 128kbit ceil 128kbit burst 20kbit
tc class add dev eth0 parent 1:1 classid 1:2 htb rate 98kbit ceil 128kbit quantum 4900 burst 20kbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 30kbit ceil 128kbit quantum 1500
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 80 0xffff flowid 1:2
Bevore test: (reseted htb) -------------------------------- # tc -s class show dev eth0

Description of the test:
------------------------
On the beginning it was everything OK, after 1 min, 1:2 lost his 98kbit. Than he got sometimes his 98kbit again and sometimes he got even 30kbit.
1. Can I do something more to find out what happen? 2. What does mean: "queues are build up" ?
