Control Inbound Internet Traffic.

Dears,

How we can control (Police or shape or reserve BW ) traffic coming from
Internet to my network (download traffic). Lets say I need to shape CLASS-A
to 1 Mbps and reserve BW for CLASS-B with 2 Mbps.

First: For Policing if we policed the incoming traffic at external
interface, then fine, traffic that is coming to internal side will be
policed when it comes to internal side . But the whole traffc already came
to the external interface and already consumed the download BW of the
external interface !!

Second: For BW reservation, it is a queuing mechanism. so it has to be
applied outbound, so it will be applied to internal interface as outbound.
So again the same problem, this traffic still not guaranteed at external
interface :(

I hope you got what I am trying to explain, and hope to hear from people who
already faced this issue in life networks.

Regards.
