High Bandwidth

High Bandwidth

DDoS attacks essentially gobble up bandwidth otherwise destined for
legitimate services. Thus, a brute force method of defence is to use large
pipes and large distributed networks to provide enough bandwidth to
survive an attack.

Rate Filtering

If an attacked site peers with multiple providers, it may be the case that
one of the providers is carrying more of the flood traffic than others.
The attacked site may choose to filter access from the provider that is
carrying the majority of that traffic, or even terminate the connection
with that provider to reduce the impact of the flood.
