Scheme for Performance Improvement of P2P Live Video Streaming on LANs
With the quick development of Peer-to-Peer Live Video Streaming(P2PLVS),the traffic of streaming media has taken a great part of Internet traffic,which severely impacts those ISP′s ordinary service.Currently,there is few method which can relieve the traffic stress brought by P2PLVS applications without impacting playback performance of users.In this paper,we first analyze the common working mechanism of Mesh based P2PLVS,and then present an application-level protocol based scheme to improve the overall performance of P2PLVS for LAN users.The scheme can effectively reduce the ISP′s streaming media traffic brought by the P2PLVS peers within the LAN,and meanwhile improve their playback performance in terms of download efficiency and playback delay.Prototype System based experiments prove that for program-concentrated P2PLVS in LAN,this scheme is reliable and effective.
