Playout Adaptation for Peer-to-Peer Streaming Systems Under Churn

The authors address the problem of playout adaptation in peer-to-peer streaming systems. They propose two algorithms for playout adaptation: one coordinated and one distributed. The algorithms dynamically adapt the playback delay of the peers so that the playout miss ratio is maintained within a predefined interval. They validate the algorithms and evaluate their performance through simulations under various churn models. They show that playout adaptation is essential in peer-to-peer systems when the system size changes. At the same time, their results show that distributed adaptation performs well only if the peers in the overlay have similar playback delays.
