Limit bandwidth from the Internet

[jeff6strings]

We have a Cisco 3845 router and on the G0/0 interface we have our public switch with multiple public IP addresses (servers, routers, etc..) and on the S0/0 interface we have a DS3 Internet connection. I need to limit the bandwidth from the Internet (download) to one of the IP addresses on the G0/0 interface. I'm thinking of limiting to 256K and really need assistance with either a policy map or something equivalent.

Thanks for any help.

Our problem which prompted this is the dowload of streaming video from the Intrernet which we realized the DS3 would still be utilized until it hits the policy map on the router; if we are correct. But there was discussion that if the client on the inside of the public IP address was streaming video and the policy map applied the bandwidth restriction, the video stream would compensate to a lower quality stream in turn using less bandwidth; instead of streaming at a high quality rate maybe HD quality.

Appreciate any feedback and thanks for the replies and thanks Joseph for the config.

Yes some video streams will decrease their bandwidth consumption (and quality) if they detect packet loss (much like TCP reducing its transmission rate if it detects packet loss).

Joseph,

Thanks for the explanation as I set the interface of the router to 10 Mb full duplex and it seems to have made a difference as the traffic on our DS3 is now at a reasonable level as your explanation may be correct with regard to the video streams compensating to bandwidth, packet loss, etc..

Thanks again.
