WRR (Weighted Round Robin): All received packets will be stored into queue 1, queue 2, queue 3, and
queue 4. Users will assign a weighting for each queue. Then, WRR will re-pack all packets from four
queues based on the weightings.
For example, as showed in the above image, the weightings of each queue are 4, 2, 5, and 1. When
5600I Series starts to process all packets in these queues with WRR algorithm, a new packet will look like
the packet showed on the right hand side. Then, 5600I Series sends out the new packets.
WFQ (Weighted Fair Queuing): WFQ is a generalization of processor sharing, which allows several
sessions share the same link.

Users assign data size of each queue can be accepted by each port in "WFQ Configuration" section.
BE (Best Effort): Best Effort QoS is mainly used for data which has lower priority or can be delay. No
traffic priority will be given in BE algorithm. Hence, this algorithm is not suitable for data that has higher
priority, such as, video or voice data.
