A method and system for synchronizing internal and external network data

Abstract

The present invention relates to a method and system for synchronizing internal and external network data. In the method, the following steps are included: the external network equipment analyzes and extracts the file information of the file, and stores it in a database table. If the file contains an attachment file, the attachment file is backed up. Go to the first path, enter the file name of the attachment file into the corresponding position of the file name field in the table, move the attachment file to the second path, otherwise, delete the file, export the newly added record in the table and save it and Send to the internal network device, and send the attached file under the second path to the internal network device; the internal network device saves the received record file and attached file to the database and the fourth path respectively; the external network and the internal network device respectively Display according to the information stored in the table corresponding to the file to be displayed in the corresponding database. The invention reduces the transmission amount of files, improves the transmission efficiency, reduces the analysis amount of files in the internal network equipment, and improves the data synchronization efficiency between internal and external network equipment.

Description

technical field [0001] The invention relates to the field of data synchronization, in particular to a data synchronization method and system for internal and external networks. Background technique [0002] With the development of science and technology, the security of data information is becoming more and more important. Since different application systems have different requirements in terms of security management, these application systems need to be deployed in physical areas with different security levels. Important application systems are located in The area with a high security level is the intranet, while the general application system is located in the area with a low security level, that is, the external network. [0003] Due to the high security requirements of the internal network, the communication between the internal network and many external networks is restricted, such as the enterprise internal network, the business system in the internal network needs to ...
