Abstract:
1. A method for detecting packets during multi-units sending process, wherein all the sequence numbers of the packets are divided into non-overlapping subsets, the number of the subsets being at least equal to the number of units comprised in a sending party; each subset is assigned to a unit of the sending party; and a receiving party records a correlation between each sequence number subset and a sliding window; the method comprises: filling, by a unit of the sending party, a sequence number from its subset into a packet to be sent, and sending the packet to the receiving party; determining, by the receiving party, the sliding window corresponding to the sequence number of the packet according to the correlation between the sliding window and the sequence number subset recorded in the receiving party after the packet is received, and performing packet validity detection according to the determined sliding window and the sequence number.
