Abstract: This application provides a sequence number synchronization method. The specific method includes: A first network device sends a data packet including a first synchronization indication to a second network device, where the first synchronization indication is used to indicate the second network device and the first network device to perform a sequence number synchronization operation. The first network device receives a response packet sent by the second network device, where the response packet includes a second synchronization indication, and the second synchronization indication is used to indicate that the second network device has received the packet including the first synchronization indication.
