设计并实现一种远程文件差异同步系统(remote file synchronization system,RFSS),在系统中,根据传统rsync算法设计了一种带冲突检测的Hash表查找方法以提高计算效率,并且在服务器端采用了加解密存储的缓冲区管理方法解决了"雪崩效应"。实验结果表明,采用该方法有效地提高了计算效率,降低了网络流量,从而实现了高效、快速和安全的远程文件同步。
A remote file synchronization system-RFSS is designed and implemented. In the system, a Hash table lookup method with conflict detection is designed according to the traditional rsync algorithm to improve computational efficiency, and the encryption and decryption buffer memory management method in the server-side to solve the "avalanche effect". In this way, it can calculate the file difference more quickly, the amount of calculation on the server is brought down and the data transmitted on the network is reduced.
