Claim 7:
8. A forwarding apparatus, comprising:
an input interface configured to receive a first packet, wherein the first packet belongs to a first packet flow, and wherein the first packet flow comprises a first plurality of packets;
a first memory coupled with the input interface and configured to store the first plurality of packets;
a first transmit port coupled to the first memory and configured to send the first plurality of packets; and
a processor coupled to the input interface, the first memory, and the first transmit port and configured to perform explicit congestion notification (ECN) marking on the first packet based on information related to the first packet and according to a weighted random early detection (WRED) algorithm,
wherein the information comprises at least two of a first duration of staying in the first memory, a first usage of the first memory when receiving the first packet, whether the first packet flow is a victim of a congestion control mechanism when receiving the first packet, or a first drop priority of the first packet.
