| 中文摘要:由于电网业务数据的快速增长,集中式的数据中心无法满足电网全业务数据存储所要求的可扩展性、安全性、和低延迟。为了解决这些问题,该文提出了一种新的基于区块链的分布式云存储架构。该云存储架构利用软件定义网络技术将数据存储分散至网络边缘的雾节点,从而降低对核心网络的数据存储压力。同时所提出的模型是基于区块链技术为接入设备提供低成本、安全且按需访问的具有竞争力的存储基础设施。通过创建一个分布式的云基础设施,所提出的模型支持低成本的高性能计算。评估结果表明,所提出的分布式存储架构具有低延迟、低响应时间,存储成本开销低的优点,能够满足不断增长的电网全业务数据的存储需求。 |

| Abstract:Due to the rapid growth of grid business data, centralized data centers cannot meet the scalability, security, and low latency required for full-service data storage in the grid. In order to solve these problems, this paper proposes a new distributed cloud storage architecture based on blockchain. The cloud storage architecture uses software-defined networking technology to spread data storage to fog nodes at the edge of the network, thereby reducing data storage pressure on the core network. At the same time, the proposed model is based on blockchain technology to provide a low-cost, secure and on-demand access to a competitive storage infrastructure for access devices. By creating a distributed cloud infrastructure, the proposed model supports low-cost, high-performance computing. The evaluation results show that the proposed distributed storage architecture has the advantages of low latency, low response time and low storage cost, which can meet the growing storage requirements of full-service data of the grid. |
