Impact of flash memory on video-on-demand storage

Moonkyung Ryu, Hyojun Kim, Umakishore Ramachandran
2011 Proceedings of the second annual ACM conference on Multimedia systems - MMSys '11  
To address the performance problem of disk, buffer cache algorithms that utilize RAM have been proposed. Interval caching is a state-ofthe-art caching algorithm for a VoD server.  ...  We compare the performance of interval caching with RAM and file-level LFU with flash memory by simulation experiments.  ...  Interval caching cannot be used when the VoD server supports fast-rewind or fast-forward functionalities because the interval caching scheme assumes that the viewing streams for the same file are progressing  ...
