Embodiment Construction

[0024] Preferred embodiments of the present invention are discussed in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. It should be noted that those skilled in the art will understand that the invention may not be limited to these specific details. In other instances, well-known structures have not been shown in detail in order not to obscure the present invention.

[0025] In general data exchange systems, data sources are physically connected to data destinations. Data is passed over a transmission line between a data source and a data destination. For example, the user terminal downloads data from the Internet, or uploads data from the user terminal to the network, so as to realize data sharing.

[0026] The present invention adopts separate one-way transmission technology, that is, adopts a physically separated uplink channel as ...

Abstract

Unidirectional data transmission system includes two pieces of data interchange card in use for isolating between internal network and external network physically. Each data interchange card includes two pieces of independent unidirectional data transmission routes. Thus, physical isolation is realized between two computers of carrying out data exchange. The unidirectional transmission system is also applicable to data transmission between internal network and external network when physical isolation is needed.

Description

technical field [0001] The invention relates to a data transmission system for controlling the flow of data transmission between a source data storage body and a destination data body. More specifically, the present invention relates to one-way transmission of data between computers or between networks and between computers and networks under the premise of information isolation, isolating direct connections between computers or networks and controlling data transfer between computers or networks Flow-oriented data transmission system, also known as security isolation switching system. Background technique [0002] The convenience and speed of the network has greatly improved our work efficiency, but the openness of the network has seriously threatened the security of the network. At present, the security threats faced by the network can be roughly divided into two types: one is the threat to network data; the other is the threat to network equipment. These threats may ori...
