In dealing with DDoS attacks, it is good do remember that altough channel
capacity is a number of bits per second, router capacity is packets per
second and server performance is requests per second. Very powerful DDoS
streams containing thousands of small packets per second from random spoofed
sources can put many routers, firewalls and servers down with no more than a
DS3 of bandwidth.
