Hi

i been working tc and htb, its good and iam able to achieve some of the
things what i required for me in my office

i have question here like this

i have total bandwidth 256kbps
we have a department finace and admin

i want to  give a b/w of 64 both, either up or down to finance
and admin 128kbps up or down..

when i setup a config of my own, they able to get 128up and 128down also
same.
so fiannce dept is consuming all the b/w, so i will be problem with my admin

how do i control aggregate b/w of 128kbps either up or down

any sample config provided  will be great

advance thanks for helping

Hi hare!

tc qdisc add dev eth0 root handle 1: htb default 2 r2q 10
tc class add dev eth0 parent 1: classid 1:1 htb rate 256kbps
tc class add dev eth0 parent 1:1 classid 1:2 htb rate 64kbps ceil 64kbps
tc qdisc add dev eth0 handle 2: parent 1:2 sfq perturb 10 limit 178
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 128kbps ceil 128kbps
tc qdisc add dev eth0 handle 3: parent 1:3 sfq perturb 10 limit 357

Of course, you have to add a filter for the admin class (1:3) and above
assumes that you're using eth0 for egress. You probably want to do this in
both directions.

The sfq's above will limit the latency to 4secs (although with sfq this is
effectively much lower) - you might want to make it lower/higher.

Also note that with the setup above you're obviously not using all your
bandwidth (64+128<256). You might want to change the setup so that finance
and admin can both use up to 256kbps, but are guaranteed 64kbps and 128kbps
respectively.

If life is merely a joke, the question still remains: for whose amusement?
