在异构的跨域网络环境中,实现一种基于Erasure Code技术的跨域安全文件存储系统.在域内由域服务器、目录存储节点及基础存储设施组成.域间在形成跨域的信任联盟的同时建立分布式跨域存储网络.跨域的文件容灾采用ErasureCode文件编码及两级的文件目录结构并采用DHT方式进行目录管理.测试结果表明,该存储系统具有较高的跨域文件存储可靠性、安全性及便捷性.%In heterogeneous cross-domain network environment, realization one kind of cross-domain storage system based on erasure code technology. The domain is composed by domain servers, directory storage nodes and storage facilities. Distributed cross-domain storage network is established while trust federation is formed between different domains. Cross-domain file tolerant use erasure code technology and two levels file directory structure and DHT files directory management is adopted. Finally through the file test results show that the storage system has high reliability, safety and conveniently.
