Maximizing Utility for Content Delivery Clouds

A content delivery cloud, such as MetaCDN1 , is an integrated overlay that utilizes cloud computing to provide content delivery services to Internet end-users. While it ensures satisfactory user perceived performance, it also aims to improve the traffic activities in its world-wide distributed network and uplift the usefulness of its replicas. To realize this objective, in this paper, we measure the utility of content delivery via MetaCDN, capturing the system-specific perceived benefits. We use this utility measure to devise a request-redirection policy that ensures high performance content delivery. We also quantify a content provider’s benefits from using MetaCDN based on its user perceived performance. We conduct a proof-of-concept testbed experiment for MetaCDN to demonstrate the performance our approach and reveal our observations on the MetaCDN utility and content provider’s benefits for using it.
