The technology of this application relates to a method and apparatus. A first service packet of a target service flow received by a packet receiving node includes in-situ flow detection information, and the in-situ flow detection information includes a detection flag and a sequence number of the first service packet. When determining, based on the detection flag, that out-of-order detection needs to be performed, the packet receiving node may perform the out-of-order detection based on the sequence number of the first service packet and a sequence number of a second service packet.
