SDN: A Service Delivery Network over end-to-end DHT

The CDN (Content Delivery Network) provide access acceleration through nearly static data caching and delivery, but cannot serve non-URL located dynamic data and have HTTP transport limits. We propose a SDN (Service Delivery Network) scheme running over end-to-end DHT (Distributed Hash Table) including servers and client hosts to provide more efficient system deployment. All SDN hosts consist of a structured overlay to deliver data and provide various native applicate interface. The SDN involves the clients into workload scheduling so to alleviate the complex of servers. We implement a simple prototype to validate its advantage.
