Patent ID: 8327233

Claim:
A method for transmitting data packets, comprising: performing Forward Error Correction (FEC) coding on M data packets according to an M×N verifying matrix, so as to generate N verifying packets, wherein the N verifying packets and the M data packets form a verifying group, and M and N are positive integers; transmitting the at least one data packet and the at least one verifying packet by using a protocol based on the User Datagram Protocol (UDP); wherein, at least one of the following two kinds of packets, the at least one data packet and the at least one verifying packet, carries corresponding information independent of a packet sequence number (SN), and denoting a corresponding relation between the at least one data packet and the at least one verifying packet wherein a verifying packet of the N verifying packets carries an SN of the verifying matrix used by the verifying group to which the verifying packet belongs and a sorting SN of the verifying packet among the N verifying packets in the verifying group; and carries feature words of the M data packets of the verifying group to which the verifying packet belongs, and carries the feature words in sequence according to a transmitting sequence of the data packets in the verifying group, wherein the feature words are generated according to the corresponding data packets, and uniquely identify the corresponding data packets.
