Hail to P2P File sharing VoIP IPTV
PPLivePPStreamSOPCastTVAnts
Related Work Large-scale live streaming can be
supported by P2P Implement P2P IPTV system and give
network statistics Study an existing P2P IPTV application by
traces patterns have not the same characteristics
whether broadcasted content exhibits a live interest for users or not
Outline Introduction Goal Experiment Setup Experiment Result Conclusion Comment
Goal For a special popular event Infer global behavior of IPTV

Video peers lifetime for TVAnts
Outline Introduction Goal Experiment Setup Experiment Result Conclusion Comment
Conclusion Different traffic pattern Different download policy Different peer neighborhood Different average peer lifetime The same peer lifetime distribution
The CCDF follow Weibull distribution
Outline Introduction Goal Experiment Setup Experiment Result Conclusion Comment
Comment Easy idea Hard work But beautiful result
Weibull distribution Model P2P IPTV in other work
