Data Transmission Mechanism Between Two Network Systems

The traditional method is no longer able to meet the growing needs of network security,the single-CPU dual bus safety computer architecture(sCPU-dBUS) protected the calculated computer system security from the perspective of changing the computer architecture.An unique CPU resource and two independent high speed system bus(local bus and network bus) are contained,the CPU is connected to main bus,and the bus bridge is used to switch on/off the connection between CPU and local bus,as well as CPU and network bus.The secure operating system NetOS-I based on sCPU-dBUS network architecture is introduced,which has two independent sub-kernel operating systems,respectively,and running on the subsystems and network subsystems.
