[Abstract]:With the rapid development and popularization of network, the application of network hard disk storage system is more and more extensive. However, there are still some defects in the existing network hard disk storage system in the aspects of super large data file transmission, memory share in the transmission process, data security and breakpoint continuation. In order to solve these problems, an efficient and convenient DTOSS (Data Transmission in Online Storage System) data transmission technology is proposed. DTOSS data transmission technology is based on the directory tree structure on the server side, and realizes the transmission of super large data files by using the idea of block transmission. At the same time, DTOSS technology also improves the security of data, compresses the memory overhead in the process of transmission, and realizes the breakpoint continuation of super large data files. The experimental results show that the maximum transmission rate can be achieved by using 64MB as a single data block size in DTOSS technology. under this condition, the memory overhead is about 67MB, and the interrupt retransmission time can be saved by about 2 鈮，
