But the whole point is that I don't know how many PCs are active in the 
lan at any given point. When I am saying that 30 PCs use the line what I 
am saying is that 30 PCS are battling for bandwidth right this instant. 
I am not saying that 30 PCs are sitting behind the router. A few seconds 
later there could be 10 PCs, or 50. For example, if a minute later only 
3 PCs are active then the capped PC should be allotted 1/3 of the 
bandwidth in class 3 (up from 1/30 it was a minute ago).

Remember that SFQ (hashed on ips instead of flows) can adjust itself 
automatically to the number of currently active PCs and how much 
bandwidth each should receive. This is not the case with HTB where 
percentages have to be plugged in beforehand.

I hope this makes it clear (and I have not misunderstood what you said)

Regards,

Dimitris
