Research on Compensative Transmission of Network Backup and Recovery
网络灾备的传输补偿技术研究

Linear error correction code(LECC) of the informatics encoding theoretics is used to solve the problems of slowness and low reliability on network disaster backup of crucial data in this paper.LECC partitions the data into blocks and encodes it redundantly,then the encoded packages are transmitted in the erasure channel (Internet for exam- ple).If enough encoded packages are received,the receiver can decode the original data,regardless of which package is lost.It saves the time for package acknowledging and retransmitting,and improves the reliability of channel and the ef- ficiency of data transmission.
