[ale] Ethernet bandwidth choker

[dcorbin at enttek.com (David Corbin)]

I need a device that I can use to simulate low-bandwidth between two ethernet 
machines.  Ideally,  the box would have some limited interface to enter in  a 
desired bandwidth to simulate.  Something that works in increments of 64kbs 
would be fine.

1) Is there a correct name for such a product.
2) Any recommendations?
