Abstract: In one embodiment, a router receives a packet, and determines an intra-flow packet priority level of the packet. The router may then map the intra-flow packet priority level to a weighted random early detection (WRED) marking based on running statistics of intra-flow packet priority levels across received flows, and marks the packet with the mapped WRED marking. By placing the marked packet into an outgoing network queue for transmission, the router may then forward or drop the marked packet based on the network queue, accordingly.

Abstract translation: 在一个实施例中，路由器接收分组，并确定分组的流内分组优先级。 然后，路由器可以基于所接收的流的流内分组优先级的运行统计，将流内分组优先级映射到加权随机早期检测（WRED）标记，并且用映射的WRED标记来标记分组。 通过将标记的分组置于传出的网络队列中进行传输，则路由器然后可以相应地基于网络队列转发或丢弃标记的分组。
