Abstract
A data forwarding method includes, after congestion of an egress queue is relieved, a network device that receives a packet from an upstream node, and determines whether a storage device associated with the egress queue buffers a previous packet that belongs to a same data flow as the packet. When the storage device does not buffer the previous packet, the network device schedules the packet to the egress queue, to forward the packet to a downstream node, where the storage device is configured to receive, during congestion of the egress queue, a packet sent by the network device.
