To adhere to the premise of separation to ensure smooth flow and application isolation in a transparent network products will be deployed in a wide variety of complex network environments and data exchange is often the key point, therefore, the product should have a high processing performance, not to be the bottleneck of network switching, with a good stability; intermittent conditions can not be there, there must be adaptable, able to transparently access network, and transparent support for multiple applications. The key lies in network isolation system to control the communication of data, that is not routed through an agreement to complete the interconnection of data exchange. Since the work of the network communications hardware seven the lowest level, and can not perceive the exchange of data confidentiality, integrity, availability, controllability, repudiation and other security elements, so this should be through the access control, authentication, encryption, signature and other security mechanisms to achieve, and the realization of these mechanisms are implemented by software.
