Differents between WRR and WFQ

I do not know the differents between WFQ and WRR after reading many documnets. I feel that the principle of the two are the same that the bandwidth can be shared and packages in different queue can be dispatched in turn, which can not starve any queue.

You're correct, WRR and WFQ are much alike, and both have a principle feature not to starve any one queue.  Perhaps the biggest difference between them, WRR is generally implemented on some Cisco switches and is very limited to the number of egress queues it supports while WFQ is implemented on routers and generally supports many more egress queues.  WFQ also often supports a dynamic number of flow queues.

There are subtle differences in how the two actually share bandwidth, as there are, on switches, between WRR, DWRR, and SRR.
