Claim 15:
16. 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 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:
store the first packet in the first memory in response to not dropping the first packet based on information related to the first packet; and
perform explicit congestion notification (ECN) marking on the first packet according to a weighted random early detection (WRED) algorithm,

wherein the information comprises at least two of a duration of staying in the first memory, a usage of the first memory when the first packet is received, whether the first packet flow is a victim of a congestion control mechanism when receiving the first packet, or a drop priority of the first packet.
