News outlets and blogs will frequently compare DDoS attacks by the volume of traffic that a victim receives. Surely this makes some sense, right? The greater the volume of traffic a victim receives, the harder to mitigate an attack – right?

With enough capacity, an attack would overwhelm the victim’s network hardware with junk traffic such that they can no longer serve legitimate requests.
