Embodiment 2

[0093] Based on the internal and external network isolation communication method of the internal and external network isolation communication system in Embodiment 1, the method comprises the following steps:

[0094]Step S1, select to execute the first working mode or the second working mode, and adjust the communication connection mode between the cloud relay server 3, the network bridge 4 and the external network device 1 based on the selection result;

[0095] Step S2, establish the state of accessing the internal network from the external network or the working state of accessing the external network from the internal network, and execute the corresponding external network access communication process under the first working mode and the internal network access under the first working mode based on the determination result. A communication process, an external network access communication process in the second working mode, or an intranet access communication process in the...

Abstract

The invention provides an internal and external network isolation communication system and method in order to solve the problem that an existing local area network cannot communicate with the Internet, and belongs to the technical field of the Internet. The system comprises extranet equipment, intranet equipment, a cloud transit server and a network bridge. The method comprises the following steps: selecting to execute a first working mode or a second working mode, and adjusting a communication connection mode among a cloud transit server, a network bridge and external network equipment based on a selection result; and determining a state that the extranet accesses the intranet or a working state that the intranet accesses the extranet, and executing a corresponding access communication process based on a determined result. According to the internal and external network isolation communication system and method, internal and external network data interaction can be realized. And meanwhile, due to the interaction of isolation of the network bridge, authorization and authentication of the cloud transit server and a user-specified data protocol specification, the network security of the intranet is effectively ensured not to be influenced.

Description

technical field [0001] The invention relates to the field of Internet technology, and in particular, to a system and method for isolating internal and external networks. Background technique [0002] As a highly integrated and comprehensive application of a new generation of information technology, the Internet of Things has the characteristics of strong penetration, great driving effect and good comprehensive benefits. It is another promoter of the development of the information industry after the computer, the Internet and the mobile communication network. [0003] However, due to the consideration of network integrity and other factors, complete physical isolation is usually performed between the local area network and the Internet, that is, communication between the local area network and the Internet is impossible. With the rise and implementation of the Industrial Internet and the Internet of Things, it is imperative to carry out limited internal and external network i...
