- CQ (Custom Queuing):
✅ services a specified number of bytes in one queue before continuing to the next queue.
❌ The list incorrectly says CQ provides guaranteed bandwidth to a specific class of traffic (that’s CBWFQ).
- CBWFQ (Class-Based Weighted Fair Queuing):
✅ provides guaranteed bandwidth to a specific class of traffic.
❌ The list incorrectly says CBWFQ services a specified number of bytes per queue (that’s CQ).
So the accurate mapping should be:
- PQ: places packets into one of four priority-based queues.
- CQ: services a specified number of bytes in one queue before continuing to the next queue.
- WFQ: provides minimum guaranteed bandwidth to one or more flows.
- CBWFQ: provides guaranteed bandwidth to a specific class of traffic.
- FIFO: uses store-and-forwarding queueing.
