Description

Technical Field

[0001] The utility model relates to the technical field of network isolation, in particular to a network isolation system. Background Art

[0002] Ordinary network gateway devices generally use two identical sets of devices, one for input and the other for output, and the two are interconnected using a network interface.

[0003] The interconnection requires unidirectional operation, so one of two solutions is generally used. The first solution is to use unidirectional at the software level, in the application or operating system or driver, to limit the network card function, so that one system can only send and one system can only receive. The second solution is to use a dedicated unidirectional fiber card, a unidirectional optical module for sending and receiving, and a fiber connection.

[0004] Since network gateway devices need to have higher network performance, foreign x86 processors are traditionally chosen, resulting in domestic processors not being able to obtain network gateway functions.

[0005] In addition, the isolation function of existing network gate devices is single and cannot realize different isolation functions according to user needs, and has poor applicability.

[0006] Therefore, in the utility model patent application, the applicant carefully studied a network isolation system to solve the above problems. Utility Model Content

[0014] The network isolation card of the first network isolation unit is connected to the network isolation card of the second network isolation unit.
