ETSI, IETF and ATIS use cases for CDN Interconnection
9
Footprint extension
•
Widely popular content
•
Geographic: regional CDN + over-the-top CDN
•
Region to region: one bigger CDN from several small ones
•
Popular remote content
•
Nomadic or roaming users: tourist or expat “colonies”
•
Content distribution restrictions: geo-blocking
Offload: overload and resilience cases
CDN capability use cases
•
CDN with different features: alternative end-devices
•
Delivery format adaptation
•
Capability exchange
