WFQ and WF2Q are the most excellent PGPS algorithms and WFQ is specified as reference queueing algorithm with service guarantee by IETF.

WFQ和WF2Q是目前性能最优越的PGPS算法，其中WFQ被IETF指定为有保证业务的参考排队算法。

General bandwidth allocation algorithms, such as WFQ and DRR, have the shortcomings of high complexity and requirement for the router to manage per-flow state.

常见的带宽分配算法如wfq、DRR等分组调度算法存在着诸如计算复杂度高、需在路由器进行每流状态的管理等不足。

Weighted fair queuing (WFQ), on the other hand, allows allocation of bandwidth on a variable basis, so not all flows have to have the same bandwidth allocation.

另一方面，加权公平排队(WFQ)允许在可变的基础上分配带宽，因而不是所有的信息流都必须有相同的带宽分配。
