QoS Scheduling

Question 1

Strict priority scheduling

Answer 1

Low-priority queues are only serviced once the high-priority queues are empty. This can cause queue starvation

Question 2

Round-robin scheduling

Answer 2

This is a rather fair technique because queues are serviced in a set sequence. Real time traffic will suffer

Question 3

Weighted fair scheduling

Answer 3

By weighing the queues, the scheduling process will service some queues more often the others. Does not provide bandwidth guarantees.
