QoS conventions (queue and scheduler)

i am a little confused about the queues and the Scheduler conventions ... for example; LLQ Queue, is it a queue or a scheduler that choose packets from queues.

Thanks in advance.

Dear me7me7,

LLQ is one of the Queuing tools or mechanisms and The Low Latency Queueing feature brings strict priority queueing to Class-Based Weighted Fair Queueing (CBWFQ). So it's Queuing tool not scheduler

The scheduler always serviced the highest-priority queue first. If there was always traffic in the high priority queue, the lower-priority queues were starved of bandwidth and packets going to non-priority queues.

Dear Mohamed,

I just wanna clarify more

LLQ is Queuing tool

-Queuing evaluates the packet/frame based on Cos or Tos..etc and determine in which queue the packet will be placed

-Scheduling service all the queues and distinguish between different queues based on its priority.

Best Regards,
