Improving continuous-media playback performance with in-kernel data paths
1994
Proceedings of IEEE International Conference on Multimedia Computing and Systems MMCS-94
Preserved Fulltext
Continuous media playback suffers when a station's operating system offers insufficient 1/0 throughput. ...
Our splice mechanism supports a peer-to-peer model of 1/0 where a requesting application can associate a data source with its corresponding data sink, allowing for system optimizations in the data path ...
This causes an inherent limitation in performance, which is characteristically absent from the in-kernel data path approach. ...
