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.
