Hello, Good morning. I’m a Ph.D. candidate from University of Central Florida. I have a query, I hope you can help me with it or at least point me to the right direction. I’ve seen from PeeringDB that every ISP reveals its traffic ratio as Heavy/ Mostly Inbound or Balanced or Heavy/ Mostly Outbound. I’m wondering if there is any specific ratio numbers for them. In Norton’s Internet Peering Playbook or some other literary work, they mention the outbound:inbound traffic ratio as 1:1.2 to up to 1:3 for Balanced. But, I couldn’t find the other values. I’d really appreciate your help if you can please mention what Outbound:Inbound ratios that network admins use frequently to represent their traffic ratios for 1. Heavy Inbound: 2. Mostly Inbound: 3. Mostly Outbound: 4. Heavy Outbound: Thank you. - Prasun -- Sincerely, Prasun Kanti Dey, Ph.D. candidate, Dept. of Electrical and Computer Engineering, University of Central Florida.
