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

Conclusion
Different traffic pattern Different download policy Different peer neighborhood Different average peer lifetime The same peer lifetime distribution
The CCDF follow Weibull distribution
