A tentative model for virtualized resource-aware dynamic media-oriented service composition

As the Internet evolves into an irreplaceable service infrastructure for modern human life, a key issue to consider is that of creating and managing a rich variety of services while keeping aware of individual requirements with guaranteed QoS (Quality of Service). In this paper, we present a tentative model for virtualized resource-aware dynamic media-oriented service composition where the service overlayer, service aggregators and resource aggregators cooperate to achieve an effective coordination of the dynamically changing requirements according to user's context and resource heterogeneity. As a first step of this on-going effort, we attempt to propose a conceptual idea for resource-provisioned service overlay network called AptusNet by focusing our attention on the provisioning aspect of the service and virtualized resource components.
