•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.

Figure 23. WFQ Example

•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.
