Abstract: A method for forwarding a packet is provided. In the method: a first packet is received that includes first indication information, payload data, and a packet sequence number of the first packet in a data flow corresponding to the first packet. When a first network device determines that the first packet includes the first indication information, the first network device generates a plurality of second packets based on the first packet. Each of the plurality of second packets includes the payload data, the packet sequence number, and second indication information. The first network device separately forwards the plurality of second packets to a second network device over different forwarding paths.
