[LARTC] need BIG help

[Toth Szabolcs]

Hello all!

I hope you can help to solve my problem.

I would emulate an ADSL line for users.  The number of the users can be  1 , 2 , 5 or 100 ,...

I have an Internet line with 2Mbit /the ethernet card is 10Mbit/  and a
LAN interface width 10Mbit. /dev eth1 10Mbit/

I would use 1Mbit from the 2MBit for limited bandwidthing.
The download rate should be 384Kbit/s the upload 64Kbit/s for each limited
users.

I made the limitation. Every user who I marked width iptables was limited,
they downloaded with 384Kbit.

But when more than 3 users downloaded on same time with the max
limitted (384Kbit/s) bw  the 1Mbit was overrun.

It would be good for me when the traffic overrun the 1Mbit limit tc prog
share the 1MBit equal.  I mean (1Mbit/5,  1Mbit/100, ...  )
and in other case the limit would be (384Kbit/s) 

I tried many variation but I couldn't make that.
Please if you have any idea or know the solution write me.

Can you give us some more info?
If you use htb, the parent ceil and rate is not respected.  So each subclass 
can ue it's rate even if the sum is exceeding the parent rate/ceil.
