[Bro] Cluster+PF_RING doubt

Hi Seth, thanks for your answer,

>>- Why VMs?

We are using VM, because we are working in the Application layer of the 
cloud, we allocate VM dynamically. The Idea was to allocate VMs (Host) 
on the fly, doing load balancing between these hosts.

>> PF_Ring spreads the traffic on a single host.

According to you, PF_RING only spread network traffic inside the host 
between the CPU cores. Is it right this phrase? The cluster made by Bro 
should be just Inside a host?
To make the load balancing between several hosts, like I am trying to 
do, I should use OpenFlow or another solution? Any suggestions?

Thank you.
