Abstract:
Real-time content delivery services have recently achieved high popularity in Internet, both for professional communities and also for entertainment. In contrast with some complex architectures like Content Delivery Networks, or Content Oriented Networks, this paper considers a light architecture, working on top of the current networking IP multi-domain infrastructures. It enhances the real-time (video) content delivery, by exploiting the cases where the content object exists on several servers. The system performs an initial content server selection (based on multicriteria) considering the servers’ load status and network conditions. Then it performs in-session media dynamic flow rate adaptation. Additionally, if necessary, a server handover is triggered. All above functionalities are assembled in a unified solution. This paper is a preliminary work, to identify the main requirements and then to develop the design for a family of implementations. Different design decisions variants are analyzed and explored, proving the solution flexibility. Currently the proposed system is under implementation in the framework of a European project.
