On the Optimization of BitTorrent-Like Protocols for Interactive On-Demand Streaming Systems
This paper proposes two novel optimized BitTorrent-like protocols for
interactive multimedia streaming: the Simple Interactive Streaming Protocol
(SISP) and the Exclusive Interactive Streaming Protocol (EISP). The former
chiefly seeks a trade-off between playback continuity and data diversity, while
the latter is mostly focused on playback continuity. To assure a thorough and
up-to-date approach, related work is carefully examined and important open
issues, concerning the design of BitTorrent-like algorithms, are analyzed as
well. Through simulations, in a variety of near-real file replication
scenarios, the novel protocols are evaluated using distinct performance
metrics. Among the major findings, the final results show that the two novel
proposals are efficient and, besides, focusing on playback continuity ends up
being the best design concept to achieve high quality of service. Lastly,
avenues for further research are included at the end of this paper as well.Comment: 20 page
