Abstract

The invention aims at providing a dual-processing system network safety isolation method which is simple in structure, safe and reliable, high in transmission efficiency, enough in bandwidth and capable of realizing one-way or two-way safety isolation and based on the SRIO interface technology. The method comprises the following steps: unloading a network protocol stack to completely eradicate thepenetrability link of a network protocol, thereby realizing the one-way data safety isolation transmission or controllable two-way data safety isolation transmission of the network regions in different safety levels; since the SRIO technology supports the chip direct interconnection way, the logic layer supports the direct IO / DMA and message transfer, thereby obviously lightening the CPU load, and greatly improving the network data transmission efficiency , and the data safety isolation communication with 10G bandwidth can be realized. The method is suitable for the network boundary of the one-way or two-way safety isolation with high bandwidth traffic requirement, and is applied to the technical field of the computer network safety isolation.

Description

technical field [0001] The invention relates to the technical field of computer network security isolation, in particular to a method for network security isolation of a dual-processing system based on SRIO interface technology, which is mainly applied to the network boundary where the internal network needs to be protected from external network attacks. Background technique [0002] With the widespread use of computer and network technology, for an internal network system of an enterprise or functional department that is directly connected to the external public network, its network security features usually require that the necessary information communication between the internal network and the external network be realized. At the same time, it can effectively protect the internal network from illegal intrusion attacks from the external network. Therefore, in important fields such as government, national defense, and industrial control that require extremely high data c...
