You can police in-bound as well, but as you point out, the problem is that
the congestion has already occurred at that point.

Basically, this is more a political problem than a technical one.  You need
to limit (in some fashion) either at or behind the ISP router in Germany.
Talk nicely to them.  Buy a techie over there some beer.  Whatever makes it
work!

If you have some of your gear on the other side someplace, then make
limitations there.  But first I would try to figure out just what traffic is
causing the congestion and determine whether it's random packets, port scans
or some legitimate type of traffic.

That will help you determine which path you are talking about!

Subject: [OSL | CCIE_RS] How to Deal with QoS when the Weak Link is
outsideYour Control


Dear all
   While reviewing the material on congestion management ... I was reading
with the goal of being able to apply it. The problem is that the the
Internet connection uses different RX and TX paths (satellite DVB/SCPC link)
and so as far as the edge router (a Cisco 1760) is concerned - no traffic
ever comes in through the serial interface (that is connected to a satellite
modem) and no traffic ever leaves the router through the fastethernet
interface (connected to a switch to which the DVB and other nodes with
public ip addresses connect)

My problem is this ... how can I provide some QoS given that the link that
suffers congestion (the satellite link) is not within my control. According
to documentation, you can only apply LLQ outbound from an interface (not an
option to me ... cos that interface is on an ISP router in Germany). 

My DVB receiver is an appliance which doesn't have any way to configure QoS
on. I know i can do traffic caching on a server behind the router but i
would love some solution that utilizes my cisco equipment. I will appreciate
any suggestions
