Dynamic Bandwidth Allocation Using Dummynet

[zam]

Hi,
Currently my place using dummynet to distribute the
bandwidth allocation among users.
In my network, we have 42 VLAN, and in dummynet
configuration we divide these LANs to 3 big groups.
Let say A,B and C. By using cron daemon, we have set
up 3 configuration files namely peak.conf,
off-peak.conf and evening.conf. This file will be
rotate in respective time like in crontab. Take a look
at this sample of bandwith allocation during
evening.conf:

Group A - 700KBps
Group B - 1500KBps
Group C - 800KBps

Let say Group A using 70% of the bandwidth, and at the
same time, Group C utilize 100% of the bandwidth, is
there any ways to make sure that the balance of group
A (30%) will be given to Group C?

cheers
zam
