In this paper, we propose a novel network coding enabled NDN architecture forthe delivery of scalable video. Our scheme utilizes network coding in order toaddress the problem that arises in the original NDN protocol, where optimal useof the bandwidth and caching resources necessitates the coordination of theforwarding decisions. To optimize the performance of the proposed networkcoding based NDN protocol and render it appropriate for transmission ofscalable video, we devise a novel rate allocation algorithm that decides on theoptimal rates of Interest messages sent by clients and intermediate nodes. Thisalgorithm guarantees that the achieved flow of Data objects will maximize theaverage quality of the video delivered to the client population. To support thehandling of Interest messages and Data objects when intermediate nodes performnetwork coding, we modify the standard NDN protocol and introduce the use ofBloom filters, which store efficiently additional information about theInterest messages and Data objects. The proposed architecture is evaluated fortransmission of scalable video over PlanetLab topologies. The evaluation showsthat the proposed scheme performs very close to the optimal performance.
