 2821 routes 170kpps, 100Mbps is 149kpps unidirectionally.

 That boils down to 127bytes avarage size for unidirectional
200Mbps flow. So assuming on top of your DoS attack, you
have some real traffic there, so that whole pipe can't 
be stuffed full of 64bytes, I'd say that might be enough
if base traffic allows it.
 The more base traffic you have (IMIX >400bytes avarage) the more
you can account for other features needed, eg. RPF/ACL.

 Of course 3560 is better solution, if you can live with
the limitations of it. But in many (not all) situations, I'd dare
to put 2821 where 200Mbps is needed.
