They're a few companies that specialize in "DDOS protection type
services" one company that comes to mind is Prolexic and their  IPN
infrastructure protection service. Prolexic will basically absorbs all
attacks filter out the bad data and then deliver clean traffic back to
your network. Its completly transparent to you're clients. Its not
cheap but i've worked with a few internet based trading companies who
used this service to litigate DDOS attacks on their network
infrastructure.
