中文摘要: 随着数字资源不断发展,面对大容量的数字资源校验时,现有的文件校验方法相比于传统文件校验在执行效率、服务器资源利用率方面已有极大的提高,但仍存在不灵活、服务器资源浪费、文件校验存在限制等特性.本文提出一种基于服务器资源弹性并发处理的文件校验算法模型,利用多并发和分块读取的方式,在保证文件Hash计算理论复杂度不变的情况下,合理利用服务器资源利用率,提升文件校验效率.
Abstract:With the continuous development of digital resources, facing large-capacity digital resource verification, the existing file verification methods have greatly improved compared with the traditional file verification in terms of execution efficiency and utilization of server resources, but there are still some characteristics such as inflexibility, waste of server resources, limitations of file verification, etc. Therefore, this study proposes a new method based on server resource flexibility and concurrency. By using multi-concurrent and block-reading methods, we can rationally utilize the resource utilization of servers to improve the efficiency of file verification under the condition that the theoretical complexity of file Hash calculation remains unchanged.
