I think traffic shaping is very importent. I agree to the point that the new traffic shaping approches tends to shape on near the edges, but that would not prevent applying such approches in the core especially if its an interprise net. The shapping implemintation preferred to be implemented in switch because the hardware is simply fast and efficient. Jeremy, Would you please specify what kind of Cisco platform that you are using?

Sure we do it all the time. There are CPU limitations on the amount of total traffic that can be pushed through a router that is traffic shaping. I'm assuming because all the shaped traffic is process switched. Also you will probably want to dedicate a router to it.

Typically these are only useful near the customer connection, as you can really only shape outbound packets. (unless you traffic shape at your boarders, and have a "large" network, you've already paid for the traffic by the time you discard it.)
