[LARTC] equal bandwidth for all IPs

[LARTC] equal bandwidth for all IPs

[ro0ot]

Hi,

How can I set equal bandwidth of 512kbit downlink and 256kbit uplink for 
every single IP address of 254 IP addresses I have in my LAN?

Regards,
ro0ot

you will have to use classful traffic shaping (QOS) with HTB / CBQ / HSFC.
go to www.lartc.org <http://www.lartc.org> and they have a pretty good 
document on how to get it up and running pretty fast :-)

if u run in to any problems come back and ask :-)

Do you mean creating class for every IP or you know some other solution that I'm looking for a long time with no success?

See:
  http://wipl-wrr.sourceforge.net/

The system is made by: Christian Worm Mortensen (worm at dkik.dk)

To quote his announce email:

  "The WRR scheduler is an extension to the Traffic Control/network
  bandwidth management part of the Linux kernels. The scheduler was
  developed to support distributing bandwidth on a shared Internet
  connection fairly between local machines."

I know a couple of systems which are using WRR in production, but I have 
not tried it my self.

I use it at about 5 locations, largest one having ~1400 computers. Works like a
charm.

Fore easy to use script check out my distribution Route Hat
http://www.routehat.org
(the script is of course usable in other distributions too supposing you have
all the patches in iproute/iptables/kernel)

Yours sincerely,
Peter

You could aswell as wrr consider esfq - you can only roughly divide what 
bandwidth you have, but the advantage over wrr is that you can choose a 
queue length for your link speed.

I don't think you can di it with wrr and if you are shaping download 
from the internet it could be better.

ESFQ is good, but isn't a panacea. You still can use esfq as a queueing
discipline for wrr's subclasses. In fact it's a perfect match, because you have
both fair division among sources AND among the connections made from the same
IP.

You don't have to do this directly with WRR, but you can do it with HTB "above"
WRR. As for download, you can use IMQ.

Check out Route Hat's tc script. I was able to reach fair internet bandwidth
division for a peak of 700 users on a 8MBit line. Of course heavy P2P users
complained, but casual users were happy and so were the gamers, because they had
low latency with low but sustained transfer rate.

I agree wrr is better than esfq in many ways. I also haven't used it or 
looked at it for some time, so may be totally wrong about what you can 
and can't do with it :-)

What I meant was I don't think you can choose one length for the whole 
wrr class - you can add queues to wrr like you can htb classes and you 
can limit those, but you have one for each user - so with many users and 
shaping from the wrong end of a slow link you end up with a total queue 
length that is too long to keep good control of the link.

The above may not be such an issue depending on the speed of the link 
and the number of users active at any one time.

Andy.
