• Weight Round Robin (WRR): All received packets will be stored into Queue 1, Queue 2, Queue 3, and
Queue 4. Assign a weight value for each queue. Then, WRR will re-assemble all packets from the four
queues based on the weight assignments.
Figure 22. WRR Example
For example, Figure 22 shows the weight value of each queue, ranging from 4, 2, 5, and 1. When the 2160
starts to process all of the packets in these queues with WRR, a new packet develops based on the weight
assignments. Then, the 2160 sends out the new packet.
• Weighted Fair Queuing (WFQ): WFQ is a generalization of processor sharing, which allows several ses-
sions to share the same link. Refer to “WFQ Configuration” on page 52 to assign the data size of each
queue that can be accepted by each port.

• Best Effort (BE): The BE Queue Type is used for data applications that have low priority or the potential to
delay. BE does not use traffic priority or weight assignments, therefore BE is not recommended for high pri-
ority data, such as video or voice.
