Abstract: This paper focuses on the design of a control plane for cloud-based adaptive video streaming delivery networks. By employing feedback control techniques, we design a dynamical resource allocation controller which throttles the number of virtual machines in a cloud-based CDN with the goal of minimizing the distribution costs while providing the highest video quality to the user. Results indicate that our resource allocation controller is able to significantly decrease distribution costs and to provide a high video quality to the user.
