Surfing Peer-to-Peer IPTV: Distributed Channel Switching

摘要: It is now common for IPTV systems attracting millions of users to be based on a peer-to-peer (P2P) architecture. In such systems, each channel typically associated with one P2P overlay network connecting the users. This significantly enhances user experience by relieving source from dealing all connections. Yet, joining process resulting in peer integrated usually requires significant amount time. As consequence, switching another far as fast solutions provided telco operators. this paper, we tackle issue efficient system. best our knowledge first study topic. First, conducted and analyzed set measurements most popular (PPlive). These reveal that contacts receives central server are utmost importance start-up process. On those neigbors, depends speed acquire video frames play. We then formulate problem, propose simple distributed algorithm, an illustration concept, which aims at leveraging presence peers fasten switch The principle maintains neighbors involved other channels, providing good upon switching. Finally, simulations show approach leads substantial improvements algorithmic solution does not have any prerequisite overlays, it appears appealing add-on existing systems.
