Improving Continuous-Media Playback Performance with In-Kernel Data Paths

  title={Improving Continuous-Media Playback Performance with In-Kernel Data Paths},
  author={Kevin R. Fall and Joseph Pasquale},
Continuous media playback suffers when a station’s operating system offers insufficient 1/0 throughput. Conventional 1/0 system structures support a memory-oriented read and write interface requiring the execution of user-level processes t o facilitate playback, and can incur throughput degradation due to unnecessary data copies. Our splice mechanism supports a peer-to-peer model of 1/0 where a requesting application can associate a da ta source with its corresponding da ta sink, allowing for… CONTINUE READING
