To use this feature, you must create multi-consumer queues and enqueue the messages into these multi-consumer queues
Each class must have a queuing discipline to determine how packets are enqueued and dequeued.
Typically, multiple data access operations are enqueued in an internal command buffer in the disk drive.
Next, any enqueued commands are executed in order.
Each packet is then buffered and enqueued for transmission.
