摘要: This paper presents the design and evaluation of an adaptive streaming mechanism from multiple senders to a single receiver in Peer-to-Peer (P2P) networks, called P2P Adaptive Layered Streaming, or PALS. PALS is receiver-driven mechanism. It enables peer orchestrate quality single, layer-encoded video stream congestion-controlled senders, able support spectrum noninteractive applications. The primary challenge that available bandwidth individual peers not known priori, could significantly change during delivery. In PALS, periodically performs adaptation based on aggregate all determine: (i) overall (i.e number layers) can be collectively delivered by more importantly (ii) specific subset packets should order gracefully cope with any sudden their bandwidth. Our detailed simulation-based evaluations illustrate effectively several angles dynamics system including: variations, participation, partially content at different peers. We also demonstrate importance coordination among examine key tradeoffs for
