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.
