Josh, 
That’s great. I’m assuming your traffic is mainly inbound. So, my question is, 
do you have a threshold that defines your traffic ratio type.
I’m taking an example from this thread. Say, your average incoming traffic is 
~45 gbps, and outgoing traffic is ~4.5 gbps. So, your outbound:inbound = 1:10. 
What are you? Heavy Inbound?
Extending this example, if your ratio is 1:7 or 1:6, then, what would you claim 
to be? A ‘Mostly Inbound’? Or still call yourself as Heavy Inbound? I’m just 
trying to understand what is the community practice?
Thank you.
