QoS Hardware Queues vs Software Queues

QoS hardware queues scheduling


A [QoS](/qos) software queue is a queue on which you can configure queueing mechanisms.  These dynamically use areas of RAM to create constructs that will function as configured. All of these functions use the main CPU and RAM to operate. This is different than [hardware queues](/qos-hardware-queues-scheduling) where queues are configured in hardware.
