Differentiated service
As to the differentiated service, if a special service is to be transmitted in a network, each packet should be
specified with a corresponding QoS tag. The switch uses this QoS rule to conduct classification and complete
the intelligent queuing. The QoS of the switch provides Strict Priority (SP), Weighted Round Robin (WRR),
Deficit Round Robin (DRR) and First-Come-First-Served (FCFS).
46.1.3 Queue Algorithm of QoS
Each queue algorithm is the important basis to realize QoS. The QoS of the switch provides the following
algorithms: Strict Priority (SP), Weighted Round Robin (WRR), Deficit Round Robin (DRR) and First-Come-
First-Served (FCFS).
