[c-nsp] Policing Confusion

[Church, Charles]

Agree.  We've used this inbound as well on our links to our peers for
P2P traffic.  Works pretty well, as long as it's TCP and you're shaping
it.

I've used inbound policing and shaping on heavily congested links with
some
success - it has the effect of applying back-pressure to the incoming
streams - delaying ACKs and dropping packets; therefore slowing down
subsequent traffic. It isn't perfect but it does work to a degree - it
just
isn't as good as outbound.
