Distributed Throughput Maximization in Hybrid-Forwarding P2P VoD Applications

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, the authors propose a hybrid-forwarding P2P VoD architecture, which integrates both the buffer-forwarding approach and storage-forwarding approach. Furthermore, they develop a distributed algorithm to maximize the throughput.
