[LARTC] traffic control based on the downloaded bytes

[LARTC] traffic control based on the downloaded bytes

[Gabor Csuri]

Hi All,

 I'm new on this list. I'm the admin of the server in our house.
We have a 768k/128k DSL line.
There are 11 flats using this bandwith without any control.
Some of them are "high donwloader" and the browsing speed is decreasing a
lot when the downloaders are waken up. :(
I have an idea how the downloaders and the browsers can use this bandwith
without any conflict.
My question is: Is it possible with iproute2 ?
My idea: I define a bandwith to downloaders (maybe 512k).
If any of the downloading thread exceed a limit (maybe 4Mbyte) it passed
into the 512k bandwith.
How can I do this trick?

Thank you for your help in advice, Gabor.

There is a length match in iptables.  But I don't know if it will work.
You can also use squid and uses the delay pools in squid.

But why don't you put all the bandwidth eating traffic in 1 class and give it 
a lower bandwith?  If there is no other traffic, they can use the full link, 
but if there is other traffic, other traffis is served first.

Hi Kenneth,
 I've taken a look to wondershaper and I think this is a half-solution for
me.
I can set up priority by port-number and other properties but I think I
can't separate packet which is a part of a 70KB gif image (part of a web
page) or it's a part of a 800MB CD image coming from a website also. This is
my problem.

Thanks, Gabor.

You have to use some tricks if you want to do this.  See my previous post.  I 
think the delay pools of squid are the best solution.  The problem is that tc 
nor iptables has an idea about what's transferred.  Squids does.
