Because we are not sure how much bandwidth high
priority traffic needs ( number of subscriber may vary
with time), bandwidth allocation policy between
different QoS level has to be ajusted from time to
time. So, there comes a problem,  how to minimize the
cost of network management? 

My question is, could those default queueing policy
adjust bandwidth allocation policy according to real
traffic requirement automatically? if not, how to
control the network management complexity when QoS &
WRED are deployed ? 


thanks
