In your example, we assume that Traffic A has been configured to be attached to an LLQ scheduler, and that is what you mean by priority traffic. Also, we assume that Traffic B and C are functioning in a round robin format without weighting.

If this is the case, then yes this is correct.

I hope this has been helpful!
