Abstract :
In peer-to-peer (P2P) video-on-demand (VoD) systems, a scalable source coding is a promising solution to provide heterogeneous peers with different video quality. In a scalable P2P VoD system, the received video quality at each peer is dependent on the throughput if the packet redundancy has been addressed with coding techniques. In this paper, we propose a hybrid-forwarding P2P VoD architecture, which integrates both the buffer-forwarding approach and storage-forwarding approach. Furthermore, we develop a distributed algorithm to maximize the throughput. Through simulations, we demonstrate that the hybrid-forwarding architecture can obtain a much higher throughput compared to the architecture with only buffer- forwarding links or with only storage-forwarding links.
