QoE Content Distribution Network for Cloud Architecture

Cloud Service has become now a real trend in the development of network services. It is a concept of deporting resources and services on remote servers as opposed to traditional hosting on the user workstation. In fact, cloud services require more bandwidth due to high quality media. Content Distribution Network (CDN) with a mechanism of replication of information among multiple servers is a solution to support high request volume and ameliorate network quality. Integrating Cloud concept into Content Distribution Network (CDN) is an effective approach to improve network quality. In this paper, we propose a Content Distribution Network Cloud Architecture (CDNCA). Our approach is based not only on Quality of Service criteria (QoS) (e.g. round trip time, network hops, loss rate, etc.) but also on the Quality of Experience that represents end-users perception and satisfaction. Experimental results show that CDNCA yields significant improvements over traditional approaches.
