scan-edf
(foldoc) | Scan-EDF
A variation of the Scan disk aceess
algorithm for use in a real-time environment where, in
general, requests are served according to {Earliest Deadline
First}. If two requests share the same deadline, they may be
reorganised according to Scan.
A typical example is a video server that retrieves video data
from a hard disk. The playback of a video impose tight
real-time constraints but if the server retrieves data once
every second for each video channel, Scan-EDF can be applied,
reducing the seek overhead.
