Yes, for instance we are doing traffic shaping of a 10 MB ethernet
down to 256K for one of our customers. We use a Cisco 2514 (you have
to have IOS 11.2 or above for the traffic shaping). Then changing
bandwidth is just a command line configuration away (This uses one router
and no CSU's). We have also done this by using 2 routers and 2 CSU's
You can get 2 OR-HS's for instance and 2 low end CSU's. (I even got it
to work with one 2514 by directing packets from one ether/serial port
set out to a CSU, across dry T-1, another CSU, and into another
ether/serial port set thus eliminating one router). By running a short
dry T-1 and controlling the channels you can also throttle his bandwidth.
Or you can use a BSD box and two ethernet cards. All of these solutions
should come in at the same or lower cost than most dedicated throttle
boxes.
