Multilevel Feedback Queue (cont.)
- Three queues:
- Q1 - time quantum is 10 milliseconds, FCFS.
- Q2 - time quantum is 40 milliseconds, FCFS.
- Q3 - First Come First Serve.
- A new process enters Q1. If it does not complete in first quantum, it is degraded to Q2. If it does not complete in first quantum, it is degraded to Q3.
- Inter queue scheduling is strict priority.
