Note that a kind of sender-pays is already used in practice as all big content providers pay for CDN on a per GB basis, and the CDN company in turn pays for bandwidth.
- guessWhy 14y agoSure, but this was the case before CDNs as well. Unless you are a Tier 1 network you usually pay a fee to your upstream carrier. However, the ITU would like to charge across many networks and discriminate based on the type of service provided. So if data from your network A reaches the customer through networks B, C and finally D, then D would like to charge you to deliver it and not slow down things artificially.
- ripperdoc 14y agoBut that is what CDNs do. A content provider, such as Apple, will pay both for their upstream carrier access, AND for the CDN access. And the CDN will effectively pay each network on the way to the destination, by renting their lines and hosting servers at their PoPs. CDN is a QoS service, it's just that the access networks feel they aren't getting part of that cake.
