Segment-sending Schedule in Data-driven Overlay Network

Data-driven overlay network is suitable for live-event streaming, because it can provide relatively-continuous streaming even in dynamic environment. In terms of improving streaming quality, prior work covered membership management, buffer map exchange, segment requesting schedule, etc. In this paper, we address the problem of segment-sending schedule on the segment-providing node, which may also affect the streaming quality. The schedule methods we discuss include FIFO schedule, lower-sequence favored schedule, and higher-sequence favored schedule. Simulation results show that if users care playing continuity much more than playing delay, the higher-sequence favored schedule brings the best streaming quality; however, if users care playing delay much more than playing continuity, lower-sequence favored schedule is the preferred choice. Through this work, we find another way to improve streaming quality in data-driven overlay network.
