Analyzing Peer Selection Policies for BitTorrent Multimedia On-Demand Streaming Systems in Internet
The adaptation of the BitTorrent protocol to multimedia on-demand streaming
systems essentially lies on the modification of its two core algorithms, namely
the piece and the peer selection policies, respectively. Much more attention
has though been given to the piece selection policy. Within this context, this
article proposes three novel peer selection policies for the design of
BitTorrent-like protocols targeted at that type of systems: Select Balanced
Neighbour Policy (SBNP), Select Regular Neighbour Policy (SRNP), and Select
Optimistic Neighbour Policy (SONP). These proposals are validated through a
competitive analysis based on simulations which encompass a variety of
multimedia scenarios, defined in function of important characterization
parameters such as content type, content size, and client interactivity
profile. Service time, number of clients served and efficiency retrieving
coefficient are the performance metrics assessed in the analysis. The final
results mainly show that the novel proposals constitute scalable solutions that
may be considered for real project designs. Lastly, future work is included in
the conclusion of this paper.Comment: 19 PAGE
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
