ABSTRACT

·         The advantages and principles of the cloud, as pay as you go business model, geographical dispersion of resources.

·         CCDN can provide a viable and cost effective solution for realizing content delivery networks and services.

·         The problem is decomposed to graph partitioning and replica placement problems while appropriate cost models are introduced.

·         The performance of the proposed hierarchical CCDN framework is assessed via modeling and simulation.

·         The Goal of CCDN is a hierarchical framework is proposed and evaluated  an efficient and scalable solution of content distribution over a multi-provider networked cloud.

·         In cloud environment, where inter and intra cloud communication resources are simultaneously considered in traditional cloud computing resoursce.

·         Cloud-oriented Content Delivery Networks (CCDNs) constitute a promising alternative to traditional CDNs.

·         Presentation of numerical results to demonstrate the entire life cycle of the assessment process and the emerging trade-offs.

·         The efficiency of introducing social metrics in the resource mapping process was demonstrated in the context of network virtualization.
