[LARTC] How to limit per tcp session ?

[LARTC] How to limit per tcp session ?

[Rio Martin]

Dear folks,
I ve fully read lartc.txt document to make sure my question still unexplained 
in that document. I want to limit per tcp session, how to do that with HTB or 
CBQ ? 

Inside lartc.txt, there is an example for full NAT QoS solution, but thats not 
what i meant. 

Thanks..

Regards,
Rio Martin.

Yes, I would be interested to hear any ideas on how to do this.  Think 
of running a hosted ASP type box where people can connect from anywhere, 
but you want to limit each to (say) a max of 5Kbyte/s, perhaps with some 
burstable excess, but that's optional.

I've been told previously that this was not possible for the current setup
(though I'd be happy to be corrected now).  I was wondering how one would
go about funding such an effort to be added to the current tc?  I've heard
from several people who would be interested, and it seems that it should
be feasible to add to the current tc programs (though I admit ignorance in
the simplicity).

If there are any kernel/tc developers reading, I'd be interested in
finding out what it would take to have this added (as apparently would
others).

Thanks,

Bill

I'm so surprised with all reply from the list. I thought someone has figured 
it out how :))

Okay, then let me describe whats on my mind to help develope this project (if 
someone dare to start make a project)

The idea perhaps like this:
Let say i'm goin to download some graphics from www.lartc.org. The first 
session i opened my browser, created connection localhost:3101 --> 
www.lartc.org:80, the 2nd, localhost:3102 --> www.lartc.org:80, and so on.
So as you could see, this is the key. Source port, not Destination port.
Every time you open new window of your browser and connect to some host, they 
create other originating port which is completely different from the 1st.

If i am crazy enough, then i'll create script to write and put Originating 
port of some host or network from 1 until 65535 into qdisc. But i dont think 
this is a good solution for this and i dont think there is no side effect for 
this.

I think, i'll let developers figure it out.
Thanks once again.

Regards,.
Rio Martin.

Hmm, I think the ESFQ module *might* be able to do a little of what you 
ask if you hash on port?  Worth a look anyway.  In fact you might even 
be able to tweak the code to hash on something different?

How many concurrent tcp connections per page depends on the browser and 
server settings - both tweakable, so you would get different speeds 
depending on site/browser combination.

Why do you need to do per tcp? There may be a better way to solve your 
problem.

You could probably do the hash bit, but (e)sfq doesn't rate limit, so 
rate per tcp would vary with the number of connections.

My reason is not web traffic; it's citrix.  I know that each user will
have one port open between their computer and the server.  I want what
he's wanting (rate limiting per session) for that.  I think that he wants
something similar (since he mentioned interest as an ASP), but he was just
using an easier to visualize example.
