Description
A large number of peer-to-peer streaming systems has been
proposed and deployed in recent years. Yet, there is no
clear understanding of how these systems scale and how
multi-path and multihop transmission, properties of all
recent systems, affect the quality experienced by the peers.
In this talk we present an analytical study that considers
the relationship between delay and loss for general
overlays: we study the trade-off between the playback delay
and the probability of missing a packet and we derive bounds
on the scalability of the systems. We use an exact model of
push-based overlays to show that the bounds hold under
diverse conditions: in the presence of errors, under node
churn, and when using forward error correction and various
retransmission schemes
