Media traffic has become the major traffic of the Internet and will keep on increasing. Numerous storage services, media applications and devices have emerged to provide Internet enabled content storage and delivery capabilities. Content Delivery Networks (CDN) based on cloud storage, adopting distributed storage technology in the edge servers, enable efficient data storage and retrieval system that reduce storage cost and provide effective resource utilization. However, current CDNs based on cloud storage, do not utilize distributed storage on edge servers, with each edge server having a complete copy of the content files to be served. In this paper we propose to implement co-operative push based content outsourcing mechanism in CDN. This solution will split the media content (video file) from the cloud onto multiple edge servers and study its performance gain in CDN arena.
