The entire video distribution chain is considered in the project, covering a wide range of entities involved in this process. Examples of these entities are headend, edge cloud, Content Distribution Network (CDN), core backbone network, Radio Access Network (RAN) as well as fixed and mobile terminals. Related to this, one of the most difficult research questions is regarding the provision of minimum end-to-end power consumption for video streams combined with the best possible Quality of Experience (QoE) obtained at the terminal. It requires solving a number of sophisticated research questions, among them modelling and optimization problems. The paper first provides an overview of video distribution networks, which is followed by a short presentation of the CONVINcE project. The second part is focused on the optimization concept s...

Although the Internet community has developed two different IP-based QoS architectures, neither has been widely deployed. Overlay networks are seen as a step to address the demand for end-to-end QoS until a better solution can be obtained. As part of the telecommunication research at Blekinge Institute of Technology (BTH) in Karlskrona, Sweden we are investigating new theories and algorithms concerning QoS routing. We are in the process of developing Overlay Routing Protocol (ORP), a framework for overlay QoS routing consisting of two protocols: Route Discovery Protocol (RDP) and Route Management Protocol (RMP). In this paper we describe RDP and provide preliminary simulation results for it.
