An interleaving crescent broadcasting protocol for near video-on-demand services
This work presents a novel interleaving crescent broadcasting protocol for near video-on-demand service. The interleaving crescent broadcasting protocol is a trade-off among the subscribers access latency, maximum buffer requirement, needed subscribers bandwidth, and maximum disk I/O transfer rate. A longer subscribers access latency may cause a subscriber to leave. A lower maximum buffer requirement, a lower needed subscribers bandwidth, and a lower maximum disk I/O transfer rate reduce subscribers costs. The interleaving crescent broadcasting protocol not only makes access latency shorter, but also lowers the overall systems cost. We prove the correctness of the interleaving crescent protocol; provide mathematical analyses to demonstrate its efficiency.
