User-centric Content Distribution Network Architecture

Nowadays, the end-users have multitude of offers that make service prices decrease in using a network environment with multiple-operators and multiple-network. Consequently, the competition between network providers increases. The customer is today in a strong position with ability to select the best one among different competing providers. Besides similar pricing schemes, which are a useful decision aid for users, their choices are also influenced by expected and experience quality. So, the interest of service providers in how users perceive usability, reliability, quality and price-worthiness has increased. As a consequence, the QoE notion has been introduced to help service providers to take into account the user perception and satisfaction. In this paper, we propose an end-to-end QoE model applied to a Content Distribution Network architecture.
