Re: Traffic ratio of an ISP

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

Hi William, 
Ha ha! Thanks for pointing that out. I’m not related to any ISP at all, so this is something new. I understand, 
PeeringDB is just a basic guideline and ISPs put their own information about their traffic ratios. I’m interested to 
know whether ISPs check their own accumulated traffic and then set their own outbound:inbound traffic ratios threshold 
to declare themselves as Heavy Outbound/ Inbound or Balanced. Or, is there some kind of rough understanding among 
networking community to treat certain ratios as Heavy/ Mostly Inbound/ Outbound. 
Thank you.
