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。
Moreover, WAXP carries all control information in packet headers, thus the advantage of requiring no per-flow state on relay nodes significantly improves the scalability of the protocol.
此外，WAXP将所需控制信息包含在专用的包头中，无需转发节点维护每流信息，增强了协议的扩展性。
With this algorithm, the router can avoid maintaining per flow state and avoid complicated per flow buffering and scheduling.
算法还使路由器避免了维护每个流的状态信息以及对单个流进行的复杂的队列管理和调度。
