S/RTBH can deal with any type of packet-flooding DDoS at layer-3, up  
to the capacity of the platform in question.  It sounds as if a) you  
should investigate getting DDoS mitigation assistance from your  
upstreams and/or b) moving from your currently software-based platform  
to a hardware-based platform at your edge to provide increased  
performance (this holds true irrespective of which vendor you select  
for your edge platform).

If you move to a hardware-based edge platform, be sure to first  
investigate all the particulars of its uRPF implementation so as to  
ensure that you can use it for S/RTBH, and if at all possible, test it  
before buying.

      History is a great teacher, but it also lies with impunity.
