Hi, All,
I went through the HTB test section on www.docum.org. One thing I am very interested in
is the scripts Stef was using:
BW1=$1'kbps' BW2=`expr 100 - $1` BW2=$BW2'kbps' tc qdisc del dev eth0 root handle 1: tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps ceil 100kbps burst 2k tc class add dev eth0 parent 1:1 classid 1:10 htb rate $BW1 ceil 100kbps burst 2k tc class add dev eth0 parent 1:1 classid 1:11 htb rate $BW2 ceil 100kbps burst 2k tc filter add dev eth0 parent 1: protocol ip prio 3 handle 1 fw classid 10:10 tc filter add dev eth0 parent 1: protocol ip prio 3 handle 2 fw classid 10:11 iptables -F iptables -X iptables -N acc_0 iptables -N acc_1 iptables -A OUTPUT -t mangle -p tcp --dport 2000 -j MARK --set-mark 1 iptables -A OUTPUT -t mangle -p tcp --dport 2001 -j MARK --set-mark 2 iptables -A OUTPUT -p tcp --dport 2000 -j acc_0 iptables -A OUTPUT -p tcp --dport 2001 -j acc_1 It seems we could dynamically change the bandwidth allocation between children. But can we use dynamic bandwidth for the parent? I mean can I use a variable to replace 100kbps in the parent queue defination and change it whenever this script file is called? This way, the scripts will work with dynamic bandwidth environment, I can monitor the bandwidth I have currently, and give it to the scripts dynamically by calling the script file with the bandwidth parameter. Is this practical? Has anybody tried it before? James |
