On interactive systems it is essential to ensure reasonable response times to users. Reducing the variance of response times is still an important goal, but it is not sufficient to prevent an occasional user from suffering indefinite postponement.What additional mechanism would you incorporate into a disk scheduling discipline on an interactive system to help ensure reasonable response times and to avoid the possibility of indefinite postponement?
What will be an ideal response?
The simplest way to avoid indefinite postponement, given that some discipline other
than FCFS is being used, is to incorporate an aging mechanism; the priority of a waiting
request increases with time until it becomes so high that it exceeds the priority of all other
requests and receives service.
