Abstract:

In this talk, I will first present a simple model for analyzing the
performance of p2p streaming, based on our paper published recently in
ICNP 2007.  Although p2p streaming has already been proven quite
successful in deployed systems (such as PPLive), we believe our model is
the first analytical model to study such systems. Using this approach, we
are able to analytically compare a couple of simple piece selectin
strategies: Greedy (or sequential) and Rarest First, and identify the
better strategy under different scenarios and performance metrics. We then
show why a mixed strategy can out-perform both. I will then briefly talk
about our recent work in modeling p2p streaming when peers are not
synchronized in their playback.
