Traffic ratio of an ISP

Wed Jun 19 20:58:15 UTC 2019

Thank you Aaron, 
This is great. This gives an interesting insight regarding CDN as they seem to play a big role here. However, in general, what do you call your ISP as? A 'Heavy Inbound' or 'Mostly Inbound'? Is there any community standard about this ratio (having 1:10 or higher) to be treated as Heavy Inbound? Or this is just a rough estimation?

Thank you.

But, I do have local caching of 4 big name cdn cache providers, so that might alter the 1:10 ratio I see on my actual inet links (which do not include the local cdn traffic)
