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: Messages are sent from a first network device to a second network device across a network. The network includes a network portion with an expected random packet loss rate. The actual packet loss rate for packets sent across the network is compared to the expected random packet loss rate. A determination is made that the actual packet loss rate is greater than the expected random packet loss rate. Compensation for network congestion is performed in response to the determination that the actual packet loss rate exceeds the expected random packet loss rate.
