Hi,
I work for an ISP which we have many customers who buy our dedicated bandwidth service. We have implemented the QoS police on output port directed to their router. Here is the problem, Lets consider customer "A" has bought 10Gbps BW, we have implemented police action with "Drop" exceed rate on egress QoS policy-map (Aggregation Router), Customer sends lots of request to the internet sites which accumulated return traffic from those servers exceed the PIR, so we "Drop" the packets... in this scenario the traffic first comes from our Link to the higher tier ISP, then traffic utilizes our core network links and at egress port gets dropped, even if we enforce PIR on our trunk's ingress from higher tier ISP, still the trunk gets utilized and then at our side traffic gets dropped, And finally the question, What is the practical way to avoid our link to higher tier ISP gets utilized for such customers?
Thank you,
Ali
