摘　　要：利用闲置的计算机的设备及带宽构建成一个基于共享模式的存储系统,是一个有价值的研究方向,基于该模式构建的分布式云存储系统具有利用空闲资源,提高社会资源利用率的特点。在该方向上拥有较为成熟的体系和解决方案的是IPFS(InterPlanetary File System,星际文件系统)。IPFS是一个去中心化的分布式文件系统,其是一个针对于全球范围的结合区块链技术的共享模式的分布式存储系统。而其系统非常庞大和复杂。基于人类生活的习惯,往往主要在某一片区域内活动,多数情况仅需要特定一个区域内的服务。根据中国架设的互联网的结构,在同一片区域内的节点之间连通性相对较好,延迟相对较低,且容易达到较高的网速。因此本研究将会设计并实现一个基于区域共享的云存储系统,该系统相比IPFS,具备更好更高效的区域服务性能和更低的区域服务成本,以及更轻量级、对硬件的要求更低的系统。Using idle computer equipment and bandwidth to build a storage system based on a shared mode is a valuable research direction.A distributed cloud storage system based on this mode has the characteristics of using idle resources to improve the utilization of social resources.The IPFS(InterPlanetary File System,InterPlanetary File System)project has a more mature system and solution in this direction.IPFS is a decentralized distributed file system,and it is a distributed storage system for a global sharing model combined with blockchain technology.The system is very large and complex.Based on the habits of human life,activities tend to be mainly in a certain area,and most of the time,only services in a specific area are needed.According to the structure of the Internet set up in China,the connectivity between nodes in the same area is relatively good,the delay is relatively low,and it is easy to achieve higher network speeds.Therefore,this research will design and implement a cloud storage system based on regional sharing.Compared with IPFS,this system has better and more efficient regional service performance,lower regional service cost.And which lighter the system,lower the requirements.
