Re: [LARTC] Ethloop?

[King Yung Tong <tong@cs.dal.ca>]

Thank you for you answer, 1:10 is incresed but 1:20 is also increased and 
increase to the specific rate if I add 100kbps to every line. 

In my case, I would like to put all the extra to 1:10 only, is that means
I have to give 1:11 ceil to 10kbps. If it is, is that means I don't need 
prio paramter? How prio parameter works?


echo Clean all the tc setup
./tc qdisc del dev lo root

./tc qdisc add dev lo root handle 1: htb default 12

./tc class add dev lo parent 1: classid 1:1 htb rate 100kbps ceil 100kbps
./tc class add dev lo parent 1:1 classid 1:2 htb rate 40kbps ceil 100kbps
./tc class add dev lo parent 1:2 classid 1:10 htb rate 30kbps ceil 100kbps
prio 0
./tc class add dev lo parent 1:2 classid 1:11 htb rate 10kbps ceil 100kbps <-- 10Kbps??
prio 1
./tc class add dev lo parent 1:1 classid 1:12 htb rate 60kbps ceil 100kbps 

echo qdisc
./tc qdisc add dev lo parent 1:10 handle 20: pfifo limit 5
./tc qdisc add dev lo parent 1:11 handle 30: pfifo limit 5
./tc qdisc add dev lo parent 1:12 handle 40: sfq perturb 10
