Embodiment Construction

[0032] The present invention provides a method for file interaction between networks, which is applied to a system including a first gateway server and a second gateway server, the first gateway server is connected to a network with lower security requirements, and the second gateway The server is connected to a network with higher security performance requirements; or the first gateway server is connected to a network with higher security performance requirements, and the second gateway server is connected to a network with lower security performance requirements. The method is as figure 1 shown, including the following steps:

[0033] In step s101, the first gateway server and the second gateway server respectively set one-to-one corresponding directories.

[0034] In step s102, the first gateway server acquires a new file and stores it in a designated directory of the first gateway server. Before the first gateway server stores the new file in the specified directory, it ...

Abstract

The invention discloses a method for alternating files between networks, which comprises a first gateway server and a second gateway server. The first gateway server is used to obtain new files and to store the files into a designated catalog of the first gateway server, and the second gateway server is used to duplicate the new files to a corresponding catalog in the second gateway server through universal series bus USB connection. The method uses a mode of USB mirror images to finish alternation between an inner network and an outer network on the file level, IP chain circuits are strictly prevented from the inner network on a physics chain circuit, network virus can not enter local area networks, and the network transmission safety degree is improved.

Description

technical field [0001] The invention relates to the technical field of video and audio editing, in particular to a system for file interaction between networks. Background technique [0002] In the LAN for professional applications, in order to ensure the high security of the network, the internal LAN is from a certain point of view a completely closed information island, which is specially built for certain professional applications. It is strictly forbidden to connect to the office network, Internet network and other networks connected to the outside world that are often used in daily life. Files stored on other types of media may also bring deadly viruses if they are copied into the internal LAN without internal LAN authentication. Therefore, the measures that are often adopted are: disable the optical drives and floppy drives of all client devices in the network, and shield all USB (Universal Serial Bus) ports of the devices. The files that the user must import are uni...
