摘要
当前冗余数据去除研究成果存在冗余数据检测准确性差、去冗延迟长和去冗率低的问题,提出并设计基于集成网络的激光标刻冗余快速滤除系统。选用IPG公司的光纤激光器和SCANLAB扫描激光振镜构建激光标刻体系,获取激光标刻数据库。冗余滤除系统主要由客户端和中间件两部分组成,客户端职责为计算激光标刻数据相似度、获得标刻数据元信息、为去冗申请用户提供申请注册界面和数据文件访问界面。中间件职责为处理用户请求、存储标刻数据文件元信息和处理用户对标刻数据的详细操作。系统主要运行流程为:从数据库中选取标刻数据,计算标刻数据相似度并传输至去冗中间件,中间件判断相似度是否满足冗余特性;假设相似度不满足冗余特性,去冗客户端将数据文件上传至指定数据库;假设相似度满足冗余特性,客户端将标刻数据元信息传输至中间件;中间件删除冗余标刻数据,并更新数据库。实验结果表明,该系统冗余数据检测精度和去冗率高、运行延迟短,具有可靠性。
The current research results of redundant data removal have the problems of poor accuracy of redundant data detection,long delay and low rate of redundancy. A laser-based redundant fast filtering system based on integrated network is proposed and designed. The laser marking system was constructed by using IPG’s fiber laser and SCANLAB scanning laser galvanometer to obtain the laser marking database. The redundant filtering system is mainly composed of a client and a middleware. The client is responsible for calculating the similarity of the laser marking data,obtaining the marking data element information,and providing the application registration interface and the data file access interface for the deduplication application user. The middleware responsibilities are to process user requests,store the metadata of the marked data files,and process the user’s detailed operations on the marked data. The main operation process of the system is selecting the marking data from the database,calculating the similarity of the marking data and transmitting it to the deduplication middleware,and determining whether the similarity satisfies the redundancy characteristic in the middleware,assuming that the similarity does not satisfy the redundancy characteristic. The client uploads the data file to the specified database if the similarity does not satisfy the redundancy feature. Otherwise,the client transmits the marked data element information to the middleware. The middleware deletes the redundant marking data and updates the database. The experimental results show that the system has high reliability,high deduplication rate and short running delay.
