[LARTC] How to define class type hierarchy of speeds?

[LARTC] How to define class type hierarchy of speeds?

[Beat Meier]

Hi

I'm very very new to tc iproute etc and have read the LARTC howto.
What I want to do is create some "master" classes of bandwidth limit and
below that per ip address which "inherits" from this master class.

Example:

one queue for 128Kbps
other queue for 256Kbps

What I want now is that for example in "class" 128Kbps the ip
10.0.0.5, 10.0.0.8 etc. goes BUT every ip adress will have 128Kbps.
The same for 256Kbps.
128Kbps
  |_ 10.0.0.5
  |_ 10.0.0.8 

256Kbpss
  |_ 10.0.0.6
  |_ 10.0.0.7

Is there now way to do that without create for any ip address its own
"master" class?
Do I have to do it like in example 15.1 (Cookbook) in the howto i.e.
if I have 1000 ip addresses they are all flat there in?


It would be nice to add such an example to ilustrate that.
What I have noticed there are a lot of example but always with 2 different
speeds but no one with customers of the same speed, same queueing disiplines
but should not share the bandwidth but have each one the full speficied
bandwidth.
Or do I have overlooked or missinterpreted this examples?

Thanks for any information!

Beat

I don't know if such a scheduler exists. With HTB, you could do 
it, but you would have to create a separate class per user. 
Which is not that much different from what this scheduler would 
do, as it has to keep track of every single IP's bandwidth 
either way.

Example 15.1 seems to be based on CBQ. I did not have much luck 
with this scheduler myself. But as far as I know, it also would 
require you to create one separate class per user.

I do not know such a script, since I'm doing traffic shaping for home 
use only. If you're looking for a script that does not primarily work 
by prioritizing traffic classes, but which works on a per-user basis,
you could have a look at my own script. (http://www.metamorpher.de/fairnat)
That is if you're willing to regard my former flatmates as customers and 
my former linux-based old PC router as high-end internet gateway.

The script will by far not be flexible enough for a project of your 
scale, but at least it's user based and I put some effort into 
documenting it, so maybe it will be useful as an example to you.

Kind regards
