<p>A method for detecting a sequence number of packet for transmission of multi-units comprises: the sequence numbers of all packets are divided into some subsets in advance, the subsets are not overlap each other, and the number of the subsets equal to at least the number of the unit included in the transmitting side, and the each subset is allocated to one unit. The receiving side determines the sliding window according to the every subset, and records the corresponded relation between the sliding window and the sequence number subset. And then the receiving side determines whether the packet is a legal packet according to the corresponding relation and the sequence number of the packet transmitted by the transmitting side. At the same time, a packet transmitting apparatus, a packet receiving apparatus and a detecting system of packet sequence number for transmission of multi-units are provided. Through it, the sequence number transmitted by each unit in the transmitting side is not overlap, and after receiving the packet, the receiving side finds the corresponded sliding window according to the sequence number, and detects the legality of the packet according to the sliding window, improving the accuracy rate of the legality detecting in the packet, and avoiding the packet loss.</p> |
