Abstract:
Handling digital audio and video data ("continuous media") in a general-purpose file system can lead to performance problems. File systems typically optimize overall average performance, while many audio/video applications need guaranteed worst-case performance. These guarantees cannot be provided by fast hardware alone; we must also consider the interrelated software issues of file layout on disk, disk scheduling, buffer space management, and admission control, The Continuous Media File System (CMFS) is a prototype file system that addresses these issues.
