  • 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.
