(Single choice) When planning QoS, it is necessary to plan reasonably according to the service,...

In campus/access QoS planning on Huawei devices, queue scheduling commonly supports RR, WRR/DRR, and (optionally) strict-priority. WRR (Weighted Round Robin) assigns larger weights to high-priority queues so they receive more transmission opportunities and bandwidth than lower-priority queues while still serving all queues. Therefore, when ensuring better treatment for high-priority services under round-robin–type scheduling, WRR is the recommended choice.
