Subject: [LARTC] Guarantee ICMP respond time ?
Date: Tue, 14 Feb 2006 20:35:40 +0000	[thread overview]
Message-ID: <43F23F1C.9060505@gmail.com> (raw)

Hello to all people there .
Can i guarantee ICMP respond time no metter how loaded is internet line .
i have typical NATed enviroiment   like

External IP |linux router| LAN - 192.168.0.0/24

i have example setup with IMQ but is it possible to be done also if i
attache htb to eth0 and eth1 for example .

if i start shaper ping i better that without shaper but it's not
guarantted i mean response  time is not like constant.

Maybe i'm missing something.
Is it possible with HTB ot with something else like CBQ ?
here is my example setup




echo "Loading Traffic Shaper IMQ0 Upload"
tc qdisc  del dev imq0 root
tc qdisc  add dev imq0 root handle 2: htb default 333 r2q 1

tc class  add dev imq0 parent 2: classid 2:2 htb rate 192kbit

#ICMP
tc class  add dev imq0 parent 2:2 classid 2:30 htb rate 32kbit prio 0
tc filter add dev imq0 parent  2:0 protocol ip handle 5 fw classid 2:30
tc qdisc  add dev imq0 parent 2:30 handle 30: sfq perturb 1



tc class  add dev imq0 parent 2:2 classid 2:24 htb rate 96kbit ceil

tc filter add dev imq0 parent  2:0 protocol ip handle 1 fw classid 2:24

tc filter add dev imq0 parent  2:0 protocol ip handle 3 fw classid 2:28
#tc qdisc  add dev imq0 parent 2:28 handle 28: sfq perturb 10
