ABSTRACT:
The present invention discloses a method for detecting sequence number of the packet during multi-units sending process, wherein all of the sequence numbers of the packets are pre-divided into non-overlapping subsets, the number of the subsets being at least equal to the number of units comprised by the sending party, and each subset is assigned to a unit; the receiving party determines a sliding window according to each subset, and records the correlation between the sliding window and the sequence number subset; then, the receiving party determines whether the packet is a valid packet according to the correlation and the sequence number of the packet sent from the sending party. At the same time, the invention discloses a packet sending device, a packet receiving device, and a system for detecting sequence number of the packet during multi-units sending process. With the invention, the sequence numbers of the packets sent by the units of the sending party are not overlapped, and after the receiving party receives a packet, it finds the corresponding sliding window according to the sequence number and detects the validity of the packet, so that the accuracy of packet validity detection may be improved, and packet loss may be avoided.
