Re: Traffic ratio of an ISP

[Prasun Dey <prasun () nevada unr edu>]

Thank you, Mike.
From an outsider, I don’t have any information of an ISP’s traffic numbers. And this may be confidential unless we are 
using any measurement platform, which CAIDA is doing. To get a rough idea about any ISP’s traffic outbound:inbound 
ratio I can only see it's PeeringDB label. But, the question is whether there is any community decided values against 
these labels? 
Like, 
1:2 = Balanced
1:5 = Mostly Inbound
1:10 = Heavy Inbound
10:1 = Heavy Outbound
I just came up with these values. They don’t mean anything. I don’t have any solid evidence or source to support them. 
So, my question is, what people actually use? Or, it totally depends on the ISPs and they vary.
