Thank you everyone for responding to my question. Looks like MQC with
traffic policing is the way to go. The only question is should I use
policing and use qos to prioritize traffic, or should I use CAR to provide
the traffic shaping? The goal is to make the gig interface send and receive
at a consistent rate of 155Mbps. And once I put in the QOS configuration
and specify bandwidth for each type of traffic, is this bandwidth
a percentage of the total bandwidth of 1Gig port, or is it intelligent
enought to allocate from the total bandwidth of 155 on the sonet?
Thanks much.
