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?
I never tried it but why not?
But how can you know the maximum bandwidth ?? If you limit all the traffic to
200kbit, and suddenly you can use 250kbit, how will you notice this?
