Pete, You are correct in general, but in many (most) cases Internet applications are TCP based, and policing them would make the TCP adjust the actual rate.

In the grand scheme of things, it's too late: you should shape as the traffic enters the bottleneck, and/or police certain classes as desired. Once the traffic arrives on your router, the congestion has occurred, and there's not much to be done about it. UDP/ICMP won't learn from shaping, so they can still overtake the internet link if you were to shape outbound to the LAN. That's where the packet shaper appliance would potentially do better: it can throttle the upload traffic to influence the download traffic responses. pt _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
