摘　　要：随着生物数据的价值被不断地挖掘出来,对其进行有效存储和高效地传输变得尤为重要。论文通过结合星际文件系统(Interplanetary File System,IPFS),提出了基于IPFS的生物数据存储传输系统,用来提高生物数据的存储传输效率;在生物数据传输方面,引入了数据交换机制和秒传机制来提高生物数据传输速度;在生物数据存储方面,通过采用一种高效的数据存储结构和引入版本控制机制来提高生物数据存储效率。与此同时,通过对生物数据的存储传输进行了深入调研,并进行对比实验验证系统的效果,实验结果表明,相比于HTTP、FTP的存储传输效率,论文提出的系统具有较高的存储效率与传输速度。The value of biological data(biodata)is constantly being explored,so it is especially important to store it efficiently.This paper proposes a biological data storage and transmission system based on IPFS by combining IPFS(Interplanetary File System),used to improve the efficiency of biological data storage transmission.In the aspect of biological data transmission,a data exchange mechanism and second transfer mechanism is introduced to improve the speed of biological data transmission.In the aspect of biological data storage,improving the biological data storage efficiency by adopting an efficient data storage structure and introducing a version control mechanism.In this paper,in-depth research on the storage and transmission of biological data,and a comparative experiment was carried out to verify the effect of the system.Experimental results show that compared with the storage and transmission efficiency of HTTP and FTP,the proposed system has higher storage efficiency and transmission speed.
