Data transmission method between heterogeneous systems and data transmission system

Abstract

The invention discloses a data transmission method between heterogeneous systems and a data transmission system, which aims at solving the problem that the data exchange between heterogeneous systems under physical network safety and defence can not be realized in the prior art. The method comprises that: a first communication system communicates with a first data channel between a data entry node of the system and a second communication system, and the data gateway node performs security detection for receiving the data sent by the second communication system through the first data channel; the first communication system disconnects the first data channel and communicates a second data channel between the data entry node and the data processing node of the system, the data processing node converts the format of the data which is received by the second data channel and undergone the security detection to the data format supported by the database of the system, and then saves the data to the database of the system. With the technical scheme of the invention, the data exchange between the heterogeneous systems under the higher data security environment can be realized.

Description

technical field [0001] The invention relates to the field of wireless network and computer technology, in particular to a data transmission method and a data transmission system between heterogeneous systems. Background technique [0002] With the vigorous development of a series of network applications such as industry informatization and e-commerce, the Internet has been widely used. However, network intrusions and network attacks have become more and more frequent. Information data security and network equipment services in the Internet The safety of the operation has increasingly become the focus of attention. [0003] For threats to network security, the existing security protection and data exchange methods mainly include: [0004] Method 1. Firewall technology based on network layer isolation. The firewall is called the first gate in the network security defense line, and it has become the most important means to isolate the enterprise network from the external netw...
