Real-Time Disk Scheduling in a Mixed-Media File System

  title={Real-Time Disk Scheduling in a Mixed-Media File System},
  author={Peter Bosch and Sape J. Mullender},
  booktitle={IEEE Real Time Technology and Applications Symposium},
This paper presents our real-time disk scheduler called the L scheduler, which optimizes unscheduled beste ort disk requests by giving priority to best-e ort disk requests while meeting real-time request deadlines. Our scheduler tries to execute real-time disk requests as much as possible in the background. Only when real-time request deadlines are endangered, our scheduler gives priority to real-time disk requests. The L disk scheduler is part of our mixed-media le system called Clockwise.
