Here's a question I haven't got an answer for that you might be able to help me with. Who pays whom in the following scenario?:
- A = User
- B = DSL Access Provider
- C = Transit Provider
- D = Video Portal
Obviously the user (A) pays the DSL Access Provider (B) a monthly fee for the DSL line rental
The Video Portal (D) pays the Transit Provider (C) since it sends a lot of data into the network towards the user.
Based on the business model User (A) might pay the Video Portal (D) a fee or the Video Portal is cross-financed in another way, e.g. advertising.
And here's the question: What is the business relationship between the DSL access provider (B) and the Transit Provider (C)? The majority of data exchanged flows from Transit Provider (C) to the DSL access provider (B). Who pays whom at this interface?
Any insight and references are greatly appreciated!
