A data exchange method and system between high and low density networks

Abstract

The present invention provides a method and system for exchanging data between high and low density networks. The method includes: obtaining message data uploaded by the business system of the low density network, transmitting and dismantling the message data and performing persistent storage; The disassembled message data is transmitted to the high-density network; the disassembled message data is transmitted and assembled on the high-density network, and the correctness and integrity of the assembled message data are verified according to the transmission identification, and corresponding feedback information is generated and stored persistently. Send the assembled message data to the high-density network business system; package, engrave and transmit the feedback information to the low-density network through the CD-ROM, analyze the feedback information and judge whether it is reissued information, and execute the corresponding reissued, cycle Follow the steps above. It can monitor whether the transmission of message data is correct and complete in real time, improve the real-time and effectiveness of data transmission, and ensure the integrity and reliability of data transmission.

Description

technical field [0001] The invention relates to the field of network data transmission, in particular to a data exchange method and system between high and low density networks. Background technique [0002] In the current office environment, the entire office network is generally divided into several independent physical areas according to the different security levels of the network, and one or more business systems are deployed in different areas; refer to figure 1 , in the same business system, the data security level is the same, and data transmission can be intercommunicated; different business systems in the same physical area have the same data security level, and data transmission can be interoperable; but business systems in different physical areas, due to data security The levels are different, and the areas are physically isolated, and data cannot be transmitted and exchanged in real time. [0003] A high-density network is a network with a higher level of secu...

AI Technical Summary

Problems solved by technology

[0004] 1. The physical networks are isolated from each other, resulting in the isolation of business systems in different regions. Data transmission cannot be performed between business systems, and the workflow is not smooth.

[0005] 2. Each business system needs to be configured with a workbench or terminal equipment, and the hardware cost is high; for business systems in different physical areas, it must be operated on different workbenches or terminal equipment; To manage multiple business systems in different regions, it is necessary to frequently switch between the secret-related network workbench and other network workbenches, which is time-consuming and laborious, and the operating experience of the staff is poor.

[0006] 3. If the business system undergoes technical transformation alone, there will be a lot of repetitive work between systems, inconsistent standards, and high cost investment
