This question pertains to Quality of Service (QoS) features in Huawei OceanStor Pacific series storage systems. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* describes: “The OceanStor Pacific series supports the traffic shaping feature, which uses the classic token bucket algorithm to control the upper limit of traffic. When tokens in the bucket are insufficient, the system generates and adds tokens based on the operations per second (OPS) and bandwidth limits defined for the QoS control object.” Traffic shaping regulates data flow to prevent network congestion and ensure fair resource allocation, making it the correct feature name for this description.
