1. A sequence number synchronization method implemented by a first network device, wherein the sequence number synchronization method comprises:
until the first network device receives, from a second network device, a response packet that indicates that the second network device has received at least one of one or more first data packets and that comprises a second synchronization indication indicating a sequence number synchronization operation is complete:
setting, in the at least one or more first data packets, a first synchronization indication for instructing the second network device and the first network device to perform the sequence number synchronization operation; and
sending, to the second network device, the one or more first data packets; and
receiving, from the second network device, the response packet.
