Yasser, -HQ = 1MBit/s to Internet -HQ has four links to branches, each branch link = 1Mbit/s -Each branch will go through the HQ to reach the HQ, as well as other branches -Each branch will access the Internet through the HQ
I hope I've got it right so far!? =] One easy way to do this would be to decide on a traffic-shaping, or policing policy for each site. Let's say I've decided to give each site 256Kbit/s access to the Internet (slightly oversubscribe my network 4*256=1024). Therefore, I need to tell the router that traffic destined for the Internet must be either shaped or policed to that rate. If the company has been using a good addressing scheme it should be rather easy to distinguish between traffic destined for the company network, versus the internet. To do this, simply right an access-list matching the networks of the company. Let's say they're using rfc1918 10.0.0.0/8 space. Simply write up an access-list denying the 10 space (you might want to include addressing necessary for a dynamic routing protocol you might have in use). Then put a permit any at the end. This will deny policing or shaping the company space, and will shape/police the Internet traffic. Then, just apply your shaping/policing with the modular QoS, a traffic-shape on the interface, or a rate-limit. If you would like configuration examples, let me know.

(Over-Booking )4) Any branch can burst traffic up to the 1M if working alone.5) Traffic of any branch should fall to a pre-defined value incase more than one branch trying to access the main branch at the same time to either have Internet or to reach another branch through the hub. I thought about QoS and I guess this target can be acheived using it. Haven't digged enough yet to figure out how this could be done and thought about hearing from you about it. Thanks for your feedback.
