LARTC - Feb 2007 - Modifying traffic shaping rates according to the amount of active users

Hi,

I''m trying to divide my bandwidth between different services, but
I''d like
to take into account the number of active users.

For example, l want divide my bandwidth between HTTP and SMTP and guarantee
HTTP 80% of the bandwidth.

However, I have many users on my system (tens of thousands) and if only 1%
of my active users are using HTTP (and the other 99% SMTP), I''d like
somehow
to change the HTTP rate to a lower limit.

Is there any way to do it automatically, assuming that each user has a
different IP?

Thanks,

How about use HTB? Set the HTTP guaranteed rate to 80%, and the upper
(ceil) limit of other classes to 100%. This then means that if HTTP is
not using 80% of your link, then the spare bandwidth not used will be
shared between the other classes.

I''m trying to avoid a situation where a small group of users get most
of the bandwidth. If just 1% of my active users are using HTTP, then
I''d like to set its rate to 10%. If 10% of the active users are using
HTTP than limit HTTP to 50%, etc'' up to 80%.

I''m trying to set dynamic rate limits according to the distribution of
IP addresses.

Based on your requirements I would use HTB.
 
Ceil (the maximum borrowed rate) HTTP traffic to 80% of your bandwidth
in one class.  In the other class ceil rate to 20%.  If HTTP needs more
bandwidth or SMTP they can borrow between each other.  
 
    Example:
        40% SMTP
        60% HTTP
 
- HTTP class will loan its additional bandwith to the SMTP class based
on the parent class rate.
initial parent 100 kbps        Borrowing
class 1 - 80 kbps         -     40
class 2 - 20 kbps         -     60
 
Hope this helps.
