Bandwith Management with Ratio like 1:4 or 1:2

i have been heart about bandwidth management with Ratio like 1:4 or 1:2. i also do some configuration like be below:

The scenario is each customer will have one vlan. i do limit for customer by IP address. i am trying to limit customer 1:2 (1MB share to 2 customer).

ip firewall mangle print

chain=forward action=mark-connection new-connection-mark= conn-mark passthrough=yes src-address=172.17.0.6

chain=forward action=mark-packet new-packet-mark=packet-mark passthrough=no connection-mark=conn-mark

queue tree print

I am not sure it is correct way to do that. can anyone suggest on this?

and i am also having problem with UDP traffic which cannot be limit by Simple Queue or Queue. Am i right?

thanks,
