Periodic scheduling in a multimedia server
Jan Korst, Verus Pronk, Emile Aarts, F. Lamerikx · 2002
We describe how the problem of effectively servicing a number of users by a multimedia server can be represented as a periodic disk scheduling problem. We give an overview of related work and present a number of new results, based on periodically servicing users that have different consumption requirements with different periods. In addition, by scheduling sets of disk accesses as batches the worst-case switching overhead is reduced.
