Reducing On-line Video Replication Problems in Content Delivery Networks by Using Adaptive Data Placement Scheme

Abstract

Content Delivery Networks have been widely implemented to provide scalable cloud services. The Content Delivery Networks (CDNs) are suffering with the resource-saving video placement problem. Examines on-line video replication and placement problems in Content delivery networks an efficient video provisioning scheme should simultaneously  utilize system resources to reduce total energy consumption and  limit replication overhead. Tend to propose a scheme known as Adaptive Data Placement (ADP) scheme that may dynamically place & reorganize video replicas among cache servers on subscribers’ arrival and departure. Both the analyses and simulation results show that adaptive information placement will reduce the number of activated cache servers with restricted replication overhead. Additionally, adaptive information placements performance is approximate to the optimal solution and also the proposed ADP scheme can achieve the more resource utilization on content delivery networks.
