Hi, everyone I has a ADSL link about 4M bandwidth, and use HTB do bandwidth management. When I config qdisc like below: tc qdisc add dev br0 root handle 1: htb default 30 tc class add dev br0 parent 1: classid 1:1 htb rate 4000kbit tc class add dev br0 parent 1:1 classid 1:10 htb rate 2000kbit ceil 4000kbit prio 0 tc class add dev br0 parent 1:1 classid 1:20 htb rate 1000kbit ceil 4000kbit prio 1 tc class add dev br0 parent 1:1 classid 1:30 htb rate 500kbit ceil 4000kbit prio 2 tc class add dev br0 parent 1:1 classid 1:40 htb rate 100kbit ceil 4000kbit prio 3 tc qdisc add dev br0 parent 1:10 handle 10: pfifo limit 10 tc qdisc add dev br0 parent 1:20 handle 20: pfifo limit 10 tc qdisc add dev br0 parent 1:30 handle 30: pfifo limit 10 tc qdisc add dev br0 parent 1:40 handle 40: pfifo limit 10 after seconds, all 4 class will reach about 1M bps, it seems like HTB not work. But if I set qdisc like below: tc qdisc add dev br0 root handle 1: htb default 30 tc class add dev br0 parent 1: classid 1:1 htb rate 2000kbit tc class add dev br0 parent 1:1 classid 1:10 htb rate 2000kbit ceil 4000kbit prio 0 tc class add dev br0 parent 1:1 classid 1:20 htb rate 1000kbit ceil 4000kbit prio 1 tc class add dev br0 parent 1:1 classid 1:30 htb rate 500kbit ceil 4000kbit prio 2 tc class add dev br0 parent 1:1 classid 1:40 htb rate 100kbit ceil 4000kbit prio 3 tc qdisc add dev br0 parent 1:10 handle 10: pfifo limit 10 tc qdisc add dev br0 parent 1:20 handle 20: pfifo limit 10 tc qdisc add dev br0 parent 1:30 handle 30: pfifo limit 10 tc qdisc add dev br0 parent 1:40 handle 40: pfifo limit 10 then bandwidth will be split fit for 2:1: 0.5: 0.1, class 1:10 will get about 2.5 M. it seems like that HTB works well. I do not understand how it works like this. Thank you for your help in advance.
