> It can detect three types of attacks:
> 1) Speed attack for certain IP (we ban every IP which exceed 1 Gbps)
> 2) Packet per second attack for certain IP (we ban every IP which
> exceed 100 000 ppps)
> 3) And flow flood (very useful mode in networks with big bandwidth/pps
> per client)
> FastNetMon can handle 2-3 million of packets per second and ~20Gbps on
