Abstract
En 中文
To address the issues of fault tolerance and retrieval efficiency in cloud storage space data, we propose an efficient cloud storage solution based on erasure codes. A cloud storage system model is designed to use erasure codes to distribute the encoded original data files across various nodes of the cloud storage system in a decentralized manner. The files are decoded by the receiver to complete data recovery and ensure high availability of the data files while optimizing redundant computing overhead during data storage, thereby improving the stability of encoding and decoding and reducing the bit error rate. Additionally, the Kademlia protocol is utilized to improve the retrieval efficiency of distributed disaster recovery storage data blocks. The proposed solution is tested on the Hadoop cloud storage platform, and the experimental results demonstrate that it not only maintains high availability but also enhances the efficiency of retrieving data files.
