Question
Match the Comware quality of service (QoS) scheduling mechanism to its use case. Which of the following correctly maps the scheduling mechanisms to their descriptions?
Use Case 1: Ensures that traffic in a higher priority queue is always forwarded before traffic in a lower priority queue; lower priority traffic might be starved out.
Use Case 2: Gives more forwarding opportunities to higher priority queues. Higher priority queues receive more bandwidth, but queues with large packets might receive more bandwidth than queues with small packets.
Use Case 3: Guarantees a specific bandwidth to traffic flows in each priority queue; divide any remaining bandwidth among queues based on relative priority.
Options
- AUse Case 1: Strict priority (SP); Use Case 2: Weighted Fair Queuing (WFQ); Use Case 3: Weighted Round Robin (WRR)
- BUse Case 1: Weighted Fair Queuing (WFQ); Use Case 2: Strict priority (SP); Use Case 3: Weighted Round Robin (WRR)
- CUse Case 1: Weighted Round Robin (WRR); Use Case 2: Weighted Fair Queuing (WFQ); Use Case 3: Strict priority (SP)
