Exploring playback continuity and delay trade-off in peer-to-peer streaming

The rapid emergence of peer-to-peer streaming has attracted many interests during last years. Video streaming continuity perceived by the user and meeting rigorous constraints on delay are the two challenging issues of main concern. In this paper, we aim to explore the trade-off between these two competing goals through a biobjective problem formulation that maximizes some notions of playback continuity while minimizing some notions of delay. Our formulation uses explicit approximations of delay and playback continuity that is beneficial for modeling trade-off between the aforementioned competing performance metrics. We then study the Pareto-optimal points of the biobjective formulation through scalarization technique. Our numerical results endorse that the proposed biobjective formulation provides a good way of performance trade-off characterization for such systems.
