Thanks Normis for the reply. Questions and comments:
CIR is committed information rate. We also have Max Limit and burst limit. At times of no congestion, we should be running at the Burst limit or Max limit. CIR is the comitted/guaranteed rate but you should be able to run at Max limit in times of no congestion. Are you indicating that if the CIR < Max limit, that Mikrotik OS only provides the CIR? That makes no sense. How can a CIR of 0 yeild no traffic in times of no congestion. If all customer are set to 0 CIR, no customer will get bandwidth? The correct implementation at times of congestion is to provide CIR to all customers and then split the Bandwidth amongst all users above the total combined CIRs. At time of no congestion, you provide Max limit. (These statements assume all queues are at the same level)
So, what exactly is the implementation that MT uses?
As far as what I am trying to accomplish, I had this other thread that disusses it. I need to provide quaranteed bandwith to some premium customers and thus the CIR for all other customers must be low:
